While driving home from work in December 2015, on a local road near my home, the engine began emitting a large steam cloud behind the vehicle and the coolant level light appeared. I pulled over and there was a major coolant leak behind the car. I had the car taken to a shop, and they identified the issues as one of the coolant pipes had separated from the engine and dumped all of the coolant on the road. In the attached image you can see the separated coolant pipe from the engine towards the back of the picture. Given the cost of repair, I had to wait until summer of 2016 to have the repair completed.

I was driving my vehicle down the highway while accelerating when I felt the car squirm and noticed a large cloud of smoke billowing from the rear of the vehicle. I pulled over and identified the issue as a catastrophic coolant leak from the engine area (rear) of the vehicle. I had the vehicle transported home and then to a repair shop where they identified the problem as a coolant line that became separated from the engine block. It was explained to me that Porsche, from the factory, used an adhesive like material to mate the connectors of the coolant lines and engine and after usage they will come apart causing coolant to be hemorrhaged onto the engine and potentially wheels/tires causing for very dangerous road conditions. During the incident I almost lost control of my vehicle due to the coolant contacting the tires which would not have otherwise happened had Porsche not manufactured their vehicles in the aforementioned way. I as well as others on the road were put in a very dangerous situation because of this manufacturing issue.

I noticed a small coolant leak from the rear drivers side of the engine. This leak became more prominent over the next several days. I took my car to the shop to have it evaluated and it was determined that 4 out of 6 coolant fittings were leaking. The design from Porsche has the coolant hoses affixed using an epoxy. After many heat cycles and time, this epoxy fails and coolant leaks from the engine. The engine must be removed to properly fix the problem and it is going to cost me approximately $6,000. This is a known issue for this car and is something Porsche should take care of.

I noticed a small pool of coolant underneath the engine compartment. Upon further research I believe the car is suffering from a common problem of the cooling fixtures that are glued onto the motor rather than welded. Amazing that a car this expensive would have such a poorly thought out problem like this. I will take the car to the dealer for estimates but I understand that an engine removal is required and all coolant fixtures need to be welded. This is a rather expensive repair for what appears to be a very flawed design. I have driven the car only a few times since the first incident and notice a pool of coolant every time the car is parked. I will not drive the car until fixed as I understand the coolant leak can be a hazard to be me while driving as well as the cars behind me if I suffer a catastrophic coolant loss.

Coolant leak caused by fitting failure. Repair requires engine removal to replace plastic fittings.

My car began leaking coolant. After towing my car to the repair shop I was told my metal coolant fittings are held in with epoxy and one of them had failed. To repair this is a $6000. 00 job. After calling the dealer I found out this is a fairly common problem but that Porsche is unwilling to do anything to help the car owners pay for it at this time. I think any time you have a common problem that is that expensive to fix you should at help a little with that problem.

The contact owns a 2007 Porsche 911 Turbo. The contact stated that antifreeze leaked into the engine and the entire under-carriage. The vehicle had neither been diagnosed nor repaired. The manufacturer was not made aware of the defect. The approximate failure mileage was 46,000. . . Updated 08-07-13 the consumer stated the loss of engine coolant was leaking onto the rears tires, causing loss of traction.

Coolant pipe leak from the fittings. Problem with the glue holding them.

I was driving the car when suddenly the low coolant light came on. Instantly, temperature started rising and I shut it down. I wasn't sure what was wrong but I found coolant all over the rear wheels and tires. After sitting on side of road, another Porsche owner stopped by. We thought the car was just overheating, so we added water. It seemed fine so I started driving home and then it happened again. We put the car on my buddy's lift and identified that the coolant was leaking from the top of the motor. After doing some research and talking to my mechanic, it appears that the coolant hoses that are bonded to the exchanger have separated. Apparently, the hose is glued to the fitting. They are both metal. My mechanic is still trying to identify a permanent fix but as of yet we haven't fixed it. I am waiting a bit to figure out the best way to fix the car to avoid future failure. The car has low miles and I am concerned after doing some research that it could happen again.

After a routine drive after an oil change service a large amount of coolant spilled out from underneath the rear of the vehicle. Under closer examination of the vehicle found loose/broken coolant fittings from behind the alternator and somewhere in the back of the engine bay. Engine will have to be removed to pinpoint the source of addtional leaks.

I would like to report that my vehicle has suffered a common reported incident related to the coolant hoses. The vehicles coolant hoses are leaking. It appears they only had adhesive and are not threaded causing them to leak. It appears very common and is a high risk as it can rupture during the drive.

I was told by similar owners like myself that the 996 and 997 platforms coolant hose rupture due to being glued from the factory. I have owned the car since it had 19,000 miles and my car had 85,000 miles and I had not had an issue so I was not sure how true it was. On Sep 29, of 2012 I was driving down the hwy with my brother when I noticed white smoke coming from the back of my vehicle. I pulled over and went to the back of the motor and the coolant hose near the alternator had pop off due to the glue not holding any longer. I'm glad that no one was hurt, but I'm afraid of the potential damage the coolant leaking if I would have been on a high rise ramp, on the highway where it could have potentially a death to myself or people following behind me. I have since talked to a few other Porsche owners and they all seem to know many other owners whom have had this issue. Some actually damaging other's property due to spin out's because of the slippery coolant. Since then I have taken percausion and had a fitting welded in place, and clamped on. I believe the factory should have addressed this issue and done it correctly vs gluing a coolant hose.

I had a known issue of coolant leak with a hosing/fitting fail on my engine. The fitting or glue/epoxy came lose causing a massive leak of coolant. The car had to be towed an extensive distance for repairs and repair was very costly for a part that was only $300. To prevent it from happening again, I had the dealer pin the fittings so that they wouldn't come lose again. For a car with less than 50k miles and the number of folks having this issue, I wanted to submit my claim. The following is the part that failed 997-106-039-72 as water neck.

Over time I noticed a coolant smell from the car whenever I would drive it with the windows down, especially when the car was in stop and go traffic. I then noticed a small puddle of fluid under the engine after the car was parked. I took the car to the service and was told the coolant pipe on the engine was loose and coolant was beginning to drip from the junction where the pipe attaches to the engine block. After some internet research, I learned that the coolant pipes are glued into the engine block and over time there is a tendency for the glue to deteriorate and the pipes to come loose in turn causing a major coolant leak in the area of the engine and rear tires. If coolant were to leak onto the rear tires, this could cause a major accident due to loss of traction of the rear tires leading to loss of control of the vehicle. I elected to have the engine removed and all 8 the coolant pipes permanently welded instead of glued as this is the only permanent and safe solution. I am appalled that Porsche would choose to glue coolant fitting on the engine when a failure could cause and accident.

I took my car to the dealer for a routine inspection. They called me to inform me that one of the fittings holding my coolant hoses had come loose and this was causing a leak of coolant into my engine compartment. They told me that it would not be safe to drive the car without replacing the coolant hose fittings since it would spray coolant all over my tires and the road. They said that coolant spilled on the road would make it very slippery and could cause cars following me to crash. The dealer replaced all fittings and hoses on the car.

I was accelerating up to highway speeds (65 mph) on a on ramp when I heard a pop under the car. I felt the car shake and decided to pull over. I discovered coolant leaking from under the car and the shake was caused by my rear tires slipping and traction control compensating for acceleration under slippery conditions. Luckily I didn't loose control and crash into another person that may have caused injury or death to them or myself. The coolant piping is a well known problem with this year model car, it is only secured by a glue like substance not clamped, it seem the glue let go and caused a pressure release in my coolant system.

Coolant leaking from a flange on top of the engine (rear engined car) caused rear tires to get wet and lose grip while driving on the street. Porsche dealer fixed the problem under warranty. Apparently this is a common issue with 2002-2012 Porsche turbo, gt2, and gt3 cars.
