Engine And Engine Cooling Problems of Porsche 911 Gt3

I had to pay thousands of dollars to have the coolant lines secured into the engine of my car. This car has a known fault in where the coolant lines come unsecured from the vehicle, dumping all coolant within seconds. Not only does this overheat the engine, but slippery coolant all over the rear tires of a vehicle means a crash can occur.

Coolant hose coupling came lose while driving the vehicle at speed, resulting in loss of all engine coolant. Coolant spilled resulted in temporary reduction of vehicle traction, fortunately without incident. Engine damage due to possible overheating is under investigation.

Sudden coolant line fitting failure. The epoxy failed and a coolant fitting completely popped out of the engine housing near the alternator. Resulted in rapid coolant loss. Car had to be towed/hauled approx 140 miles to repair facility near my home. I have not yet seen the bill for this service. I am having all coolant fittings welded to prevent this from happening to any of the other lines. Work is not yet complete but the estimated bill is $3500+.

A coolant line came loose then I was driving the car. I was very lucky I did not spin in the coolant, and get in a serious accident. This is a very serious safety issue. The lines were originally "glued" in from the factory. This was a poor design and is a weakness of the car which could have been catastrophic in terms of destorying the engine, and getting in a serious accident. In order to properly address the design issue I was quoted over $3,000 to resolve the issue. This involves taking the engine out and welding the lines. I believe Porsche should pay for the repair.

I had the 8 coolant fittings, prone to epoxy failures, secured to housings by welding. Cost for welding was $275,.

The coolant lines on this car have well known and documented failure problems. I am very concerned for my safety and the safety of my passengers and as such am going to have the repairs completed as a precautionary measure. With the failure rate of the coolant fittings on these cars, and the usually catastrophic results I do not feel safe driving this vehicle. I'm going to spend my own money to correct a problem that should have been fixed by Porsche.

I am reporting the issue of coolant line fitting failure. I have not had a failure yet but that my mechanic has advised me that this issue must be addressed and repaired before there is a catastrophic failure. This is a known and expensive issue so rather than waiting for a failure, I was advised by a mechanic that it is going to fail and needs to be repaired immediately.

No incident accured. However, based on my knowledge of the failure of the coolant fittings in my car and wanting to take a proactive stance I elected to move forward with a remedy. While at the dealership on another matter, the engine had been removed allowing limited access to a number of the coolant fittings. Since the dealer disavowed any knowedge of the problem and was therefore unwililing to help I took it upon myself to mechanically fasten those coolant fittings which I had access to. Mind you all while the dealer looked on. I provided all the tools , parts and pieces which I needed to drill and fasten those I had access to. Others , I simply safety wired the hose clamps hoping it would prevent a failure in the future. Many failures have occured at high speed track events resulting in catistrophic vehicular loses. To my knowledge there has been no loss of life which is just by the grace of god. This problem has been in existence for several years and covered many models. It was the focus of a feature article in excellence magazine, a magazine available in book stores and primarily dedicated to the Porsche brand. The Porsche factory had to be aware of the problem, but like many other issues elected to ignore it.

I drive this car on the highway and on the track approximately 5 weekends a year. I have seen multiple engine coolant pipe failures on these gt3's and I fear I will be next and fear it may cause other vehicles behind me to crash. Its not safe for these coolant lines to break which can occur on the track or the highway. It seems to be a Porsche problem in climates with lots of variations in temperature both hot and cold with the expanding of the hose and/or the glue keeping them in place.

Starting to see weeping from a pressed and glued coolant line at the engine. It will need to be addressed very soon as it is an extremely dangerous situation if it fails while driving. Coolant will pour onto the rear tires and cause the rear end to slide. I cannot drive the car until this is resolved. Very poor mfg decision by Porsche. These fittings should have been threaded, pinned or secured in some other manner. Using glue is just ridiculous.

Coolant lines / fittings welded/ pinned - mk2 mezger engine has a faulty design of coolant hoses/lines. Upon research online, I am not the only person affected but all turbo/gt3/rs/gt2 cars from 2004-current I have also come across cars with less than 10k miles that had this problem so my problem is not isolated. There has been incidence on highway where these hoses just burst or loses fitting and spills coolant contents all over the road. This also cause car to spin out since lost in pressure and traction. Very dangerous. Porsche dealer will only use different glue to fit them. Proper way is not use rubber hose but to use metal pipes and weld them so these coolant lines do not ever fall out. This could have caused catastrophic injury in public road. Porsche denies any faulty or sub-standard material that was used in a critical component of high performance engine. In order for me to fix this, I have to pay my Porsche mechanic to remove the engine, find the coolant lines, replace all of the hoses with metal pipe lines, weld them, then put it back in the engine bay. I feel that I should have have to pay for this out of pocket for safety of myself or others in pubic road. Porsche suggested that they will use the same rubber hoses with just a better adhesive glue to hold them. They will fail within time. This is a temporary fix they are offering. It is for safety of the motorist.

I was driving my car on I-79(3 lane highway) at 70 mph when I noticed a large cloud of smoke/steam from the rear of my car. I then noticed other cars pulling off to the side to get away from all the coolant spraying from my car. I pulled off to the side of the road and called for a tow truck. Ounce I was able to get Porsche dealer to look at the issue, it was indicated that my coolant fittings failed and separated from the engine(know issue).

Engine has press fit (and glued) couplings for coolant lines. When coupling fails, there is rapid coolant loss which is a toxic hazard as well as potentially dangerous to traffic.

Had coolant fittings welded to avoid catastrophic failure. Done in seattle; cost 3485 plus 250 sharkwerks fittings = 3735 total.

A coolant hose press fitting which is apparently glued into the engine block lost adhesion and disconnected. This resulted in a complete loss of coolant and a corresponding loss of control due to hot, slippery coolant coating the rear wheels of the car and road surface. Car spun and left the road but fortunately did not hit anything and coolant spill did not impact any other motorists. My research indicates that this is a common, systemic problem with this model engine and appears to be a dangerous defect in the engine construction.

I had pro-active repairs performed on my 2004 Porsche gt3 coolant system due to known issue of coolant pipes separating from the engine. I had the repair performed because I was afraid of losing control of my vehicle (it is my daily driver) or causing a crash behind me. The repairs cost me $3900 + CA state tax (7. 75%) for a total $4200+.

Failure of factory glued in coolant fitting caused an instant dump of coolant onto the rear tires of the car causing loss of control and a spin. This is a well documented problem in all Porsche gt3's and Porsche turbo's and Porsche refuses to identify the design flaw of having these fittings glued together.

I did contact Porsche twice but there has not been a response. I did have all the coolant fittings removed, cleaned and welded in. No problem since.

The car was being driven when suddenly the coolant system failed and coolant spilled from under the engine causing my car to skid out of control. The coolant also posed a hazard to other cars on the road due to the extremely slippery nature of the liquid. The car had to be towed to an independent mechanic. The coolant lines had to be replaced and welded rather than the epoxy glue that was used in the original coolant fittings. Porsche dealerships would only use epoxy to seal the fittings which would only eventually lead to another failure.

Previous owner stated that coolant lines disconnected due to failure of the fittings. Coolant was spilled all over the road behind him. Another driver barely missed the coolant but there could have been a major accident. Porsche fixed the problem under warranty, but the fittings were not welded as the fix recommends, merely re-glued. I'm afraid this will happen again.

I purchased my 2004 Porsche gt3 in may of 2009. It had just under 20,000 miles on it. In August, 2010, I was driving on track at texas motor speedway and one of the coolant fittings came loose from the engine. The epoxy that holds the press-fit coupler to one of the heat exchangers had lost its ability to retain the fitting and came disconnected. All of the engine coolant was lost in a single instance. [catastrophic coolant loss]. I had that fitting replaced by the Porsche dealer in dallas under aftermarket warranty. I can provide info regarding the on this at your request, and I have some pictures of the offending part. I had a second (and separate) fitting fail in January 2011 at 35,000 while driving on track at motorsport ranch houston. They same symptoms were found - the press-fit coupling had come loose resulting in complete coolant loss. This was also repaired with a factory replacement part under aftermarket warranty at the Porsche dealer in houston. I believe there are 8 known press-fit couplers on the gt1 engine block in the 996 and 997 model gt and turbo cars. Each of these is known to fail based on the press-fit coupler and poor design (use of epoxy on a high pressure component). I understand that this is a known problem on Porsche gt/turbo cars and has been discussed on the internet (e. G. Rennlist) for many years. 25% of mine have failed, and almost every other gt driver I know has had at least one fail.
