I had a similar experience and it worked out great. Now my g5 is new again!

Regarding the leaking G5 and Apple repair...a friend of mine had the coolant problem and after a few discussions with Apple received a brand new Mac Pro last month. Definitely worth pursuing.

My dual 2.7 G5 died last week with a bright flash of light as the coolant leaked and blew the power supply. It makes you wonder how somebody could think it was a good idea to put the power supply underneath the water cooling. I didn't have any signs like revving fans to give me a clue that something was going wrong.

Anyway, thanks to this thread, my local Apple store has agreed to repair it free of charge. They ordered in a power supply, cpu & cooler (they can't be ordered separately), and a logic board in case they needed it. It came to over $3000 australian in total. I should get it back next week. They gave me the impression that if I didn't have the extended warranty they wouldn't have repaired it for free. My Applecare extended warranty expired 6 months ago.

I think that it pays to go to an Apple owned store if have the same problem. I'm sure that it would be easier Apple to approve the repair being done by their own people, rather than being repaired by a reseller.

I have to admit that I'm a bit jealous of the people that received a new system instead of having theirs repaired. My only thoughts for the rest of us is how we could make sure that the same thing doesn't happen again in the next couple of years. How can we prevent future coolant leaks from damaging the logic board or power supply? I would have hoped that Apple had a permanent solution.

Hi, Thanks for your informative website!

My G5 Dual 2.5Ghz (purchased in 2004) crashed 27/4/09. There were clunking noises and a very strong smell of smoke. I took it to an Apple repairer. I was told the processor coolant leaked onto the mother board and then short circuited the power supply. Cost to replace parts and repair: $3,568 AU in other words it was a 'write-off' and I needed to buy a brand new computer. I rang Apple and they initially told me they hadn't heard of this problem (!!!) and it was a year out of the 3yr extended warranty that I had purchased and they couldn't do anything about it. I asked to speak to the manager. and I was passed on to Customer Relations who also told me they hadn't heard of this problem. I looked on the internet and saw many others had the same problems (I appreciate your site!).

After reading of others in the same situation I persisted with Customer Relations and she spoke to her manager and then offered me 20% off replacement parts cost (not off the repair cost) or 20% discount off new machine. I wasn't at all happy with that offer. Later after I persisted again, she offered to replace/repair at no cost to me. That's great but I'm concerned that if it is just repaired, because of it's design, it's just a matter of time before it could do it again. The product has a design problem and should've been recalled and fixed. Apple have been very pleasant to deal with but have only acted after my determined persistance. They obviously recognise the design problem but will only do something about it after you persist.

I tried very hard to get the machine replaced so that this wouldn't happen again but after significant effort they refused to budge on their offer to repair it at no cost to me so that's what I accepted. Many thanks to your site for posting all of the problems regarding this particular model.

Don't forget that unless you are doing video editing, a Mac Mini is often just as fast as a dual G5. You can put your hard drives in an external firewire case and be back in business for a lot less money.

Re: Power Mac G5s

The "design flaw" that Apple changed to improve these systems was switch to processors that don't require a freakin' *radiator* to keep them cool. Can you honestly expect that these systems are going to last forever? The cooling systems on some of those Power Macs were made by Delphi (a automotive parts manufacturer.)


Greg E.

I have a Dual 2.5 GHz G5 at work that just had the coolant leak issue. Lucky for me it wasn't disastrous - I heard a bit of a noise about a week ago and as I run Temperature Monitor all the time, quickly noticed that the average running temperature had gone from around 127F +/- 5 or so up into the 180's and 190's ... with fan usage appropriately going up. Finally it got to the 200's (while Firefox - actually the G5-optimized Minefield version - steadily chewed up 35% of the CPU while doing nothing) and due to a "Thermal Runaway Condition Detected" it put itself to sleep.

I woke it out of sleep and did a formal shutdown. After that it would not reboot - got the chimes and no video, with the fans coming on full blast a couple of minutes later. Had it taken away and to an Apple dealer in Pasadena, California (Di-No Computers - highly recommended, their Repair techs are crack and highly knowledgeable) where they said it was a coolant leak and he could tell it was recent because it hadn't dripped down onto something below where it could pool and start corroding things.

The tech recommended I call Apple and see if they would do anything about it. First level person resisted and gave me the "It's out of warranty" spiel. I told her I wouldn't even be calling if it was any other issue, but that this one was a known one and due to a design defect. I mentioned how both MacInTouch and another Mac site had coverage of this issue, and made it a point to say how the other site has a page dedicated to just this very problem, which is 27 screen fulls on a 30" monitor with the browser stretched from top to bottom!

That seemed to break her down and she sent me up a level, and the guy there was more sympathetic (but I had to repeat the same spiel). He agreed to talk to a Product Specialist for the G5 and, lo and behold, this past Saturday he called me and said they would repair it as a Warranty repair!

Needless to say I'm quite happy about this. Kudos to Apple for stepping up and taking responsibility, and to Di-No for quickly diagnosing the problem. As an employee of a U.S. Government Lab, I'm happy to have saved the taxpayers over US $1150 in parts alone!

I'm a freelance computer consultant and one of my clients called me saying his power mac G5 won't boot anymore. Upon inspection I got it to boot but noticed the fan was running way to high. I thought to reset the PMU and then run Diskwarrior. When I pulled the computer from under the table I noticed there was a small pool of water underneath where the back of the computer was. A quick google for "Mac G5 coolant leak" lead me to this great forum.

The upshot of it all is Apple has agreed to give an "out of warranty waiver." My appt. with the genius bar is two days away still. I guess they where afraid of the small bit of water damage on the wood floor it was sitting on.

Having had to fix computers back in the stone age where the only way to get info on problems was word of mouth or god forbid, calling the company's BBS with your 300bps modem.... if they even had a BBS!

In late August 2004, my husband bought for me, the newest Mac tower available, The dual processor Quad G5. It was amazing! I couldnt be more ecstatic.

Right from the start the machine had issues. Over the 5 years I had it, I called Apple countless times with various complaints. Some as simple as "I cant explain it, I just know something is wrong with this".. To having 3 New HD put in, and a new power supply....

Of course the extended warranty was up last August on its 4th Birthday. Just as I had expected (and even expressed concern to on the phone with Apple numerous times) It almost immediately started acting worse. Over the course of the next few months I was riddled with issues of the fans blowing full blast, and overall unusual performance. Then about 3 weeks ago, when in the middle of doing anything, suddenly it would just go into sleep mode. I assumed that once again the HD was going. Backed it up, used it only bare minimum, and ordered a new HD. Upon arrival my hubby did the install (computer tech) It wouldnt boot up, we started talking about what else could be wrong, it obviously wasnt the HD. I did some research and found a really good website (I cant think of it now!!) where when I posted about my Mac's symptoms (including a "water like" sound that I kept hearing), a very helpful guy mentioned that it could be a coolant leak, (and linked this site as well). As suggested I did some research about how common this issue really is of this issue on that model Mac, and how many users either got free repair or replacement machines.

Yesterday I finally was able to go to Apple. I explained my problem and my suspicions to the Genius on hand. He pulled up the serial number (containing the *long* history of problems I'm sure) opened the Mac, and the look on his face told the whole story clearly. Coolant leak confirmed.

Apparently I had a slow leak too, so it managed to destroy everything inside. He's looking, typing, looking, typing. Grabs a manager, who looks inside the machine and on the screen the other guy was typing on... I knew it wasn't a good sign when a 2nd manager came over, and the 3 of them walked away to discuss the fate of my Mac...

After about 20 minutes they all came back with the good news, they were going to replace it. The cost of the repairs, labor etc... were not worth it. In fact I suspect it was cheaper to just replace it. So they replaced it with a base model Mac Pro (which is fine really its in many ways an upgrade!) No cost to me (yippee). I asked if i could get the extended warranty since it was going to be a new computer; they said no problem. Even that was discounted. I kept waiting for them to tell me the "real" cost but at the end of the day the Mac Pro and the extended warranty cost me a hot $52.43.

No fighting, no pushing, nothing. They even transferred the data from my old HD to the new machine. 1 hour later I walked out happy as a pig...

So I wanted to share my my story, and thank both your site (and the one I can't remember, I will have to see if I still have it at work on my safari history) And give hope to other readers. The extended warranty, not only did that save me the cost and labor of 2 new hard drives, and a power supply, but it meant that every issue I had, i didnt mind calling about. I really think that was part of why it was so easy. I mean it's obvious from the beginning there was an issue....

My suggestion is, if you get someone with a bad attitude... Pack up your toys, go home and try again another day, or another store... It's worth it!

Very satisfied Apple geek, writing from my New Mac Pro...

Congratulation to Ms. Blendowski for having the patience and politeness to convince Apple to do the right thing. A word of warning, though: her AppleCare "extended warranty" (Protection Plan) expired on the machine's third birthday (it only extends the total life of the hardware warranty to three years, not by three years). (See: Thus her new machine will go off warranty in 2012.... hopefully after three uneventful years.

Correct on the length of the warranty, but on the number of birthdays, let me point out that the day one is born is a birthday the three years of warranty actually does end on the fourth birthday, technically speaking.

It happened to me. Apple store said nothing they can do since its out of warranty. dual g5 2.7. I could pay 85 $ for them to tell me its my logic board. And it would take them 5 days before they could look at my computer. (Guess long line of bad Macs). Sad to think, My G4 has outlasted my G5. Want to learn about peoples' issues with Apple, go stand in the store near the support bar. :) A day later and best feeling all day is I have to buy all new audio cards, scsi cards. Enough of my rant.


Richard Nerworse

I have a June 2004 Dual 2.5 GHz Liquid Cooled PowerMac G5 that I recently purchased for $50! Keep in mind I am not new to Mac; I have 2 new unibody MacBook Pros (15" and 17"), and a new iMac 24".

To get to the point, I bought this computer for a server. I saw the ad on craigslist and couldn't resist. When I got it, It had no RAM, graphics card, hard drive, optical drive, no fans, processor cover, or case door. It did have the air baffle though. Anyway, I bought the parts (I got them all for $100 - Yay!) I am still waiting for the parts in the mail, but in the meantime, I was wondering if the computer did have a liquid cooling leak in the future, if I could get a Mac Pro free replacement. By the way, I tested computer just with some spare RAM, and plugged it in and it seems to be fine. There are no signs of leaks.

J Man

3 things seem to happen to the G5 Macs. Coolant Leaks, PSU failure and Logic Board failures. Which, for me. makes the G5 a pretty untrustworthy computer. That's probably a good reason why people are willing to sell them for $50. Mine ended up in a shop over a year ago. The shop just ended up keeping it, because it was not worth repairing. This one had an unrepairable logic board.

Aug. 12, 2009


MacInTouch Reader

This is a rave for Apple Computers: In early July, 2009 I experienced the classic liquid cooling system failure with my 2004 Mac G5 dual 2.5 GHz PowerPC. My main logic board, power supply and cpus all destroyed. I had bought the unit new at MacMall with Applecare. Apple completely rebuilt my computer with $2,000.00 worth of parts FOR FREE.

Thanks, Apple. This is why Macs are worth the premium cost.

Renee Boyd

This is just a follow up to my previous note regarding my G5 coolant leak that happened on Sept. 2, 2009. About 15 min.'s ago, my Apple rep Anthony, called me to let me know that they are authorizing full repairs at no charge! This is Sept. 5th, Sat. (no less) and he said he just wanted to help put my mind at ease that they were taking care of it.

I am so impressed by the promptness and service once again. So far I have never been let down by Apple.

Sep. 8, 2009


Renee Boyd

Well, THAT day finally came for me too unfortunately. I was warned by a friend early July 2009 to keep an eye on my G5 because of known coolant leaks. This was the first I had ever heard of it. I have a Power Mac G5 (June 2004) 2.5GHz-DP. I bought a 1.5TB drive and began backing up both my hard drives. (Lots of video projects, photos, and music).

Last night the "jet engines" on my G5 took off and I immediately shut down. This morning, Sept. 2, 2009, I found the little green puddle under the computer. I hadn't noticed this before, but I knew what it was. I unplugged it and called Apple. They are "deciding" what they can do for me since it has long since been out of Apple Care. (they kept reminding me that the machine was not covered any longer.) I told them I understood that, but since this has been a known issue that effected many people, I had hoped they would help me out. I explained I have been a loyal Apple user for the last 20 years, and still own four different models. I have always had positive experiences in the past with Apple and hope that this will turn out to be another one.

Thanks for a place to post these issues.

Don Seher

Just had a G5 go out yesterday. Called Apple Support: no repair or replacement, since it is now considered "vintage".

Sep. 17, 2009


Jeff Schaffer

Don Seher, I wonder whether your state's laws have anything to say about "vintage" computers (or any other product, for that matter)? It's not that long ago that the G5's were being sold. I imagine that businesses that have populations of G5's might have something to say as well.


Matt W

Don, sorry to hear you can't get service on your G5, but if it's already in vintage status, that means the machine is six years old. If I remember correctly, Apple must make parts available for 6 years after a model debuts, except in California, where state law requires parts be available for 8 years. Only the very first G5 model released in June 2003 is now vintage.


Frank M.

After my G5's OS update fiasco a few months ago (perhaps accompanied by or due to graphics card hardware or software failure (radiator still intact))... one day everything working fine, next day updated OS, everything went to hell, never able to get a stable system going again (Tiger or Leopard, from scratch or otherwise, unless booted into safe mode)... decided to just bag it and got a new Power Mac back in June. Painful, but just in time apparently. And no more drip pan.

Sep. 18, 2009


Frederico R

Was only a little bit surprised to hear that a G5 which could be as much as six years old (poster did not specify age or model) was now considered "vintage", and no repair or replacement parts were offered.

Still, there used to be such a thing as the Federal Obsolescence Act (or some such name), which required a manufacturer to provide specifications, sourcing on parts and service for a full seven years from date of manufacture -- though such support could cost whatever it cost, and there is no guarantee that there would be value in such a repair. A firm I used to own nearly got sued because we did not know about this law, and, according to our attorney, we were best advised to scramble to specially manufacture the needed repair parts, at the original advertised value, for a device just inside seven years.

Thankfully, we still had the tooling and the specs, and other than a big waste of time setting up for a one-off product run, we were able to charge for the parts.

Has this act gone by the wayside, or is Apple somehow exempt? I tried to Google it, but every relevant hit on legal sites required a membership to access the article.

Perhaps notably, I believe Apple got in big trouble in the UK for iPods with bad click wheels; didn't they end up being forced to repair or replace a large number of units there under a similar consumer protection law?

Apple seems to acknowledge this idea in this document:

...which states, in part,

"Vintage products are those that were discontinued more than five and less than seven years ago.", and goes on to say, "Apple has discontinued hardware service for vintage products with the following exception: Products purchased in the state of California, United States, as required by statute. Owners of these products may obtain service and parts from Apple Service Providers within the state of California, United States."

Not trying to start a row here; the G5 is (most likely) past any possible AppleCare (though it's possible a good CC warranty extension perq could save a late 2005-2006 G5); it also appears that if the G5 in question were purchased in CA, under CA law, it must be serviced (though, again, I can't imagine too many scenarios where this could possibly be cost effective).

Just curious if any legal eagles can shed any light on this.


MacInTouch Reader

Google is your friend

Vintage products are those that were discontinued more than five and less than seven years ago. Apple has discontinued hardware service for vintage products with the following exception:

Products purchased in the state of California, United States, as required by statute. Owners of these products may obtain service and parts from Apple Service Providers within the state of California, United States.

Most PowerMac G5 models are still serviceable. Only the original PowerMac G5 models are vintage.

Knowledge is power!


Barry Nathan

Here is Apple's list of "Vintage and obsolete products:"

(Note that when there's a generic sounding name on that list, like "Power Mac G5," it refers to the original model of that line, not the later models. The later models have more specific names which mention either a vague release date or some characteristic of that model.)

Matt W is almost correct. According to the Apple page, the thresholds are 5 and 7 years after a product is discontinued.


Steven Klein

Here's a link to Apple's official take on 'Vintage' products:

"Vintage products are those that were discontinued more than five and less than seven years ago. Apple has discontinued hardware service for vintage products with the following exception:

Products purchased in the state of California, United States, as required by statute. Owners of these products may obtain service and parts from Apple Service Providers within the state of California, United States."

Note that the products must have been purchased in California, and can only be serviced there.

The article continues:

"Obsolete products are those that were discontinued more than seven years ago. Apple has discontinued all hardware service for obsolete products with no exceptions."

What this means for G5 owners:
The first PowerMac G5 was introduce on June 24, 2003, and reached vintage status 5 years later, on June 24, 2008.

The PowerMac G5 line was discontinued on August 7, 2006. The last of those won't reach vintage status until 2011. Those purchased in California will be eligible for parts & service until 2013.

While Apple no longer services those models, Don Seher isn't out of luck. Independent service providers (like myself) are more than happy to provide service & support for vintage and even obsolete Macs.

I also had a G5 go out a few weeks ago, slowly but surely. (For a while would run OK but wouldn't reboot without many many attempts; finally, wouldn't boot at all, just stuck on gray apple and fans going full blast). Finally went in to my IT dept this week, and they said it was coolant leak and it would be over $2k to repair, and that the model was about to be unsupported within a couple months. Sounds like they had seen a number of similar cases recently -- guess it was just a technology with a limited lifespan?

Sep. 19, 2009


James Earl

As I recall, I checked out the IBM specifications pages about the G5 liquid cooling chips back when they were introduced. After a serious failure history of liquid cooling in the PC world, it is interesting that the original warranty by IBM was limited to 24 months.

It's not our fault these things are failing. They are not car radiators, after all.

I would, and did recommend to my clients to avoid liquid cooling. While a neat technology, it does *not* have a solid reputation.

Sep. 24, 2009


Don McLean

Similar to the other scenario's my G5 started to act up. The computer would not boot up, although the power button was illuminated, and the fans would work themselves into a jet-like frenzy after about 15 minutes. I would have success only sporadically so I was baffled as to the cause. After reading a number of threads describing the same condition I made an appointment to have it serviced. Upon picking it up to transport I spotted the fluid, small puddle looking like Mountain Dew, under the front end of the tower. The techs at the Apple store initially disagreed with my assessment that it was a coolant leak, stating that the coolant color would be reddish in color, and thought I actually had spilled mountain dew. Anyway, long story short, they called me back after getting into the tower and acknowledged that it was indeed a coolant leak and the repairs would be covered by Apple. Yet another, satisfied "long time" Apple customer.

Nik Beachman

We had a G5 Dual 2.5 June, 04 that leaked onto power supply and caused a flash and puff of smoke. Apple tech deemed it unfixable and would not look at helping us out-as we were the second owners of machine, out of warranty etc. Despite the fact we have several in the office and are long time users etc they would take no responsibility-other than offer us a $ 100 coupon. In the end we got a mac pro with apple care. I sold the old G5 for parts, and have just heard from the guy who bought it (a computer tech)who managed to fix it for $43 using new tubing and giving it a good one-over. So Apple have proved thenselves useless, ignorant, and it would seem, unable / reluctant to fix even their own hardware?!

So, how many 5-year-old Dell or HP systems have you successfully managed to get the manufacturer to repair?

Nik Beachman commented on selling his dead G5 to a tech who fixed it cheaply. Could Nik kindly provide this chap's contact info? I have several G5's that have died due to coolant leaks and would love to get them repaired.

Took my leaking PowerMac G5 into the Apple store yesterday and they are repairing it free - no hassle, no questions asked. Thanks for a valuable resource!

First off, if a Dell or HP died, it wouldn't require one to go to a special repair center to get it worked on, you could go to basically any computer repair shop.

Secondly, the Dell/HP parts can easily be replaced with off-the-shelf components and, therefore, also won't cost an arm and a leg.

Finally, how many Dells and HPs are using an historically defective cooling system that has, for years, caused them to crash and burn?

In response to Scott's request, I suggest he read my article in the "XLR8 Your Mac" blog: PowerMac G5 Coolant Leak Repair/Overhaul.

In May 2009, my dual 2.5Ghz G5 failed due to a coolant leak. I brought it to an authorized Apple repair center, Tekserve, in New York City. Apple agreed to rebuild the machine completely even though it was out of warranty. They replaced the case, motherboard, power supply processors, one of the two hard drives, etc. - - at no charge to me. A little more than six months later, in December 2009, the computer failed again. The diagnosis this time was that the brand new processors had failed for unknown reasons. I attempted to contact the customer relations person I had previously dealt with at Apple, sending him an e-mail and leaving voice-mail messages for him. He had said, at the time of the original repair, that I should "not hesitate," to contact him in the event of further difficulties. He has not, so far, had the courtesy to respond. I am hoping to find someone at Apple to discuss this matter with and wonder if anyone has a suggestion about whom to contact. Thanks.

I came home from a trip out of town on January 30 to find my G5 dual 2.5 had died from a coolant leak that got all over the place on the inside of the machine. I called Apple on Monday (February 1) to see what they recommended, knowing that the coolant issue had been a situation they had fixed outside of warranty for others in the past, but expecting nothing. I was elevated to a supervisor, who asked me to send photos of the machine to him, and he would forward to engineering. After a week, engineering said to take the machine to the nearest Apple store, and authorized the repair of the machine. After two weeks, the machine was fixed with parts sent, but still would not operate. So, the local store called engineering again, and they could not get a reply (from their own department), and on March 4, called to tell me that they had decided to replace my G5 with a new Mac Pro machine. I am awaiting the machine, and will report what happens and how long it takes. I was told I would only get the base model, but still, on a six year old computer, Apple stood behind the machine and made a decision to assist. While I know that Apple has a record of how many machine you have owned, I have no idea if the more than 30 Macs I have owned personally in my life acted as an extra factor or not, or the fact that I currently own five machines (two desktops, a laptop, and an iPhone) that are all under Apple Care warranty, but whatever caused the goodwill, it was great to hear and great to see Apple stand behind their product. I will report back when I get the new machine.

Albert Lilly

Well, the new Mac Pro arrived and is now home. I ended up getting the base model, quad core 2.66Ghz model with the base hard drive and three gigs of RAM. Though they had me take it all home last time, Apple wanted my computer (of course), the power cord, the keyboard (which was dead, luckily I had saved it), the mouse (died a LONG time ago and I threw it away), and all the other things that would have come with the original Power Mac G5 six years ago. They even wanted (though they didn't tell me this until I got there) the old box that the machine came in, and unfortunately, they did not get that (It was long since disposed of after getting wet during the great flood of 2008 here in Indiana). The gal who worked with me was almost surly with me when I said I didn't have the box, and I was ready to walk with her poor attitude and general poor customer service. She was so surly another Apple employee took her aside and said something, and she came back much nicer, but still, it wasn't anything I could have done, she had that attitude from minute one. I have yet to fire it up, but plan to over the next few days.

Clearly, the coolant leak in my G5 was such that it fried the entire computer. Clearly, Apple wanted to make this right, and I applaud their efforts to do so. I am not going to let one surly Apple employee change my opinion of Apple. Almost everyone else I dealt with was friendly, professional, and tried at every instance to do what they could to assist. That to me is the sign of a company that is doing a lot right.

I just noticed these posts a little too late, was not aware that so many had the exact same coolant leak problems and many had their units fixed for free. Gee, Apple give me a break, I bought 2 identical brand new Dual 2.7 early 2005 G5's for a shade over 3 grand each. Last week one of the units was having real startup issues and I decided to open the cover and dust off the insides a bit when I noticed that there was a stain on the floor under my desk where the back side of the unit was sitting on. The stain was dry but definite. I looked into the bottom rear of the unit and saw flaky salt like dried light greenish stuff that I tried my best to remove. Being long out of warranty, I called 2 Apple stores and explained my problem. I also went to a computer repair shop near home and all said the same thing. Processor and/or motherboard done in by the corrosive leak and big bucks to fix. I proceeded to take out all the non-affected items in the case and put the carcass out in the sidewalk as trash. My second unit is dry and running fine as it had very little use as backup and small printing jobs. Had I known about so many with the same problem, I would have with the unit directly to Apple and speak to someone who is aware of this common issue. In digging more into this, I never found any recall of the leak problem by Apple. My problem was not the power supply but a manufacture defect. Three thousand dollar computers should last a little longer than 5 years. My daughter's Cube bought 10 years ago is as good as new, and she uses it continually without any problems.

Just one experience from Europe:

Negative feedback after calling AppleCare/Europe/Germany about one G5 2,5GHz with coolant leak.

They asked to email them photos from inside the unit and forward it to their engineers. One day later they called back and said this machine is end of life and too old, they have no spare parts for it - they are sorry?

In the past we spend over 100000 for Apple products. Longtime customers should not be treated like this?

My G5 was running fine, just a tad noisy with the fan revving. I didnt think anything of it. Turns out I have a coolant leak. Turns out coolant leak is a hazard for electrocution and fire. (not to smart putting liquid above electrical power source encased in metal). I called Apple and got a "CS" code, which basically extends the warrantee for repair or replacement for this particular issue. So - I brought it to Apple authorized service center. They diagnose the leak- and order the parts needed for repair. Apple sends the Logic Board and the Power Supply and then refuses to send the CPU. They claim they don't have any, but the truth is they are saving them only for owners in California. Now they are trying to back-pedal on the whole repair or replacement deal. I have already registered complaints with Better Business Bureau of San Jose, Hudson County NJ Division of Consumer Affairs, NJ State Div of Consumer Affairs, and put a call in to the constituent liason for my congressman Steve Rothman. I will next contact various media sources. The fact is Apple should have recalled these machines as soon as they knew there was a safety risk. I drive a 96 Mercury Grand Marquis, I was recalled about a year ago for something under the hood that could catch fire. I guess Ford//Mercury cares more about safety than Apple does. I am a persistent bugger and I have not given up. Apple will either make good on their "CS" code, no matter what I have to do. Maybe we should all band together and get a class action suit going. That'd be fun

Unless Anthony Ferrera needs to run something in classic mode, he doesn't want any repairs to his G5.

He should get a MacPro.If Apple won't give him one--even a refurb, try ebay or a dealer.

The law that covers auto recalls doesn't apply to computers. And he is lucky there is a dealer around to fix it 14 years later since Ford has had financial problems and will be dropping Mercury entirely.

When it comes to computers, they may run much longer but by the time 3-year warranty is up they are getting pretty close to obsolete.

In this case a G5 won't run Snow Leopard.

If this is his only Mac, I doubt he wants it in the shop until his case is heard.

I usually use my Macs for about 5 years before upgrading them, but in the case of my 2005 liquid-cooled G5, I sold it at my first opportunity in 2008 on eBay after reports of leaks started coming in.

Last month, a year and half after the sale, I received an e-mail from Apple to the address associated with my Apple ID asking for my feedback regarding my recent Power Mac G5 repair. I haven't contacted to the new owner, but I'd bet dollars to doughnuts that it was a coolant leak.

It seems like it's not a question of if, but when, these Macs will leak. I think anyone who still has one should sell it as soon as possible and use what money you get from it to offset the cost of a Mac Pro purchase.

While it is nice that Apple is taking an individual case approach to this problem, it seems a bit unfair that some people like me get a brand new Mac Pro, while others get nothing but a leaky computer.

In my case, nothing was automatic, and I went along with the "we'll repair" (even though I repeatedly pointed out that their estimates for repair were far MORE than a new Mac Pro would cost).

I am lucky to be near a few Apple Stores, so it was an Apple Store "genius" who initiated the trouble ticket. After I balked at paying for a repair that I knew was being done for free for others, the "genius" mentioned that I might want to talk with an Apple Customer Service rep. That, I think, made a difference. The rep took a complete report, and then told me that "engineers" would decide and have the last say. (Making clear that if they said "sorry, no fixee" there would be no further discussion).

Luckily, they said "it's fixable", just take it to an Apple Store.

Once back at the Apple Store, it was like they were only slightly in touch with the case, even after they looked it up. The "genius" wrote up the repair ticket, and I once again questioned the business sense in Apple paying for a repair that cost far more than a new machine (the cost to repair was estimated at $2700), I essentially needed a new case, power supply, mobo, etc. The "genius" agreed, but said that it's Apple policy to repair. I said fine, as long as it works when they're done with it.

About a week later, I get a call asking if I would be OK with a brand new Mac Pro. Again, I said "fine". There were some questions about software - did I use anything that would require OS9 (perhaps the only reason for keeping a G5 around), but I didn't, so they made the exchange. They removed the RAM and hard drives and gave them back to me, keeping the dead G5 while sending me home with a new Mac Pro.

Anyway, not sure why there's such a range of results for this problem.

There is much more information (as well as strategies for dealing with Apple) here:

I was one of the unfortunate users of the G5 dual (2.5 model from June 2004).

For those researching why your G5 is freaking out:
Essentially, when a G5 "bleeds out" (also referred to by some at Apple as "a bleeder"), it fries the motherboard. You will experience bizarre problems which will all seem software-related. Symptoms include: strange mouse behavior (short of finding mice poop on your pad), USB issues, failure to boot properly, failure to backup properly, and the huge indicator: the fans working overtime and occasionally screaming!

In 2009 Apple agreed to repair this issue. It took quite a bit of research and documentation of other users who had repairs done free of charge. I took the computer in to an Apple store and in April 09, I received back a computer with entirely new guts. $1200 in repairs.

Now, about 1 year and a half later, the machine is leaking out again. I am in the process of researching secondary bleedouts.

Apple Customer Service - to their credit (so far) - seems to agree. I have been issued a new case ID number and sent photos of the bleed. The rep told me it is being passed up to an engineer and I will hear back next week.

Fingers are crossed and I continue researching users who have suffered a secondary bleedout.

My G5 2.5DP just went through its leaking and repair.

Luckily I knew some people within Apple who had it approved for repair. Helps being a contract Apple Trainer every now and then.

A friend of mine actually got a new Mac Pro versus his G5 fixed... I wasn't so lucky, but I'll take a working machine over a dead one.

My concern is if/when it leaks again. Can't imagine it will be covered the next time.

Had a client's G5 that leaked out its coolant and, even though it was a year past the end of the AppleCare coverage, Apple agreed to pay for the parts. I sent off the machine to a ASP who got the "ok" from Apple (they would pay for the parts) and, when they were done, they called and said Apple paid for the whole thing. Cool.

Unfortunately, one of the CPUs was defective and, when I sent it back for a re-repair, UPS dropped the unit off their truck and essentially demolished the machine. After a few weeks of haggling (it was insured), UPS picked up the box and paid me for the insurance value. My client ended up with a new Intel iMac; she was not displeased.

I knew liquid-cooling in a computer was a bad idea back when Apple (and others) were doing it. Let's call it the last gasp of trying to wring every bit of performance out of CPUs that should never have seen the light of day. What a disaster!


Dennis Whiteman

My 2.5Ghz G5 also experienced a secondary bleed last summer. Right now, it's sitting on my floor gathering dust and I haven't done anything with it as far as attempting to get it repaired.

The second bleed involved smelling something sickly sweet a day or so before it failed, but not thinking much about it. I was controlling it remotely from my Macbook Pro when it just vanished. When I went to check on it, it was off and while it would click when I hit the power button, it never came back to life. I pulled the drives and have recovered all the data that was on it.

The first bleed the fans were blaring and when I attempted to reboot, it wouldn't finish starting up. It's six years old now and was repaired in January 2009 at no cost by Apple after weeks of haggling with support. I'm not willing to spend the same amount of time trying to get it fixed because of its age.

Barry Levine comments:

"I knew liquid-cooling in a computer was a bad idea back when Apple (and others) were doing it."

That would be continuously over the last 60 years. Please don't assume a flawed implementation means a fundamentally bad idea.


Chris Hutcheson

Mine died this year as well. A bit of a leak, overheating and racing fans. I had enough time to do one last backup before it died. Bought an iMac 27" i7, restored data from the old internal drive (which I then used as an external until it died a couple of months ago) and haven't looked back. The G5 served me well, and it was time for it to ride off into the sunset.

I had a coolent leak on my G5 in June of 2010 and at first Apple said they would repair it, then they said they would not repair it. Finally I put in a BBB complaint in and got a call from Apple saying they would repair it. However, they could not find parts and the end result was they gave me a new Mac Pro. I dont know if that will work for everyone but you may not want to take no for an answer. I would stress the safety issues if you enter a BBB report.

I purchased a used G5 that was said to be not working. When I took thing apart it was obvious that coolant had leaked out and it also took out the power supply unit. The leak started at the pump in my case. I took it all apart, got a used power supply on ebay for around $40, replaced all the hoses in the LCS and took apart and sealed the pump.

Put her all back together and she's running fine now. Pump makes whining sounds and needs replacement but a new pump is about $60.

Which Power Mac G5 models use liquid cooling?
You have outlined PM G5/2.5 DP (PCI-X), PM G5/2.7 DP (PCI-X), PM G5 "Quad Core" 2.5 all have liquid cooling system. Yet it is noted in the "MacInTouch" forum that there were leaking problems with at least two or three of G5/2.3 DP Machines, such a finding now leaves me to assume that all G5 Computers carry liquid cooling systems.

I would like to find out once and for all; Which Power Mac G5 Models use liquid cooling? and which ones use
the more conventional "computer-controlled fans"?

[ covers this in a FAQ entry linked below. -MacInTouch]

Which Power Mac G5 models use liquid cooling? Which Power Mac G5 models have been reported to have problems with the liquid cooling system?

The Power Macintosh G5/2.5 DP (PCI-X) (June 2004), Power Macintosh G5/2.7 DP (PCI-X) (Early 2005), and Power Macintosh G5 "Quad Core" (2.5) (Late 2005) all have a liquid cooling system.

My 2.5 g5 has failed to a coolant leak also. It was cheaper to get a replacement than a repair. Power supply, logic board and processors all dead. But there is a good site that focuses on this issue.
