No incident occurred. 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 knowledge of the problem and was therefore unwilling 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 occurred at high speed track events resulting in catastrophic 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.

Cooling fitting failure on porsche 911 gt3 rs 2007 with glued in fittings.
Hello, I do not have an incident yet. However, I am extremely concern that the coolant pipe will come apart while driving causing massive coolant leak. The slippery coolant can cause spins and crashes for me and other drivers around me. Thank you.

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.
Tl* the contact owns a 2007 porsche 911 gt3. The contact stated that the vehicle was taken to the dealer for routine maintenance when the mechanic advised that the hose fittings for the engine cooling system were faulty and would eventually fail. The contact was advised to have the hose fittings replaced. The vehicle was not repaired however, the contact stated that the mechanic was convinced that the component would fail. The failure mileage was 9,000 and the current mileage was 9,800. The VIN was not available.
Coolant leak noticed at coolant manifold fitting during oil change. Engine was warmed up prior to oil drain, therefore was at operating temperature. Seepage at fitting into manifold was detected by smell and then located with light and mirror. I had to have the engine removed and the fittings welded by my local independent shop. All of the fittings were glued into the castings and were prone to failure at any time.
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.
Coolant fittings were pinned after car started to show a small weeping leak on one of the fittings. Mezger engine 911's split the fittings and can cause rapid coolant loss and a sudden loss of traction.
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. Coolant spill did impact other motorists who spun out on the coolant but did not crash. 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 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.

Driving a 2007 porsche gt3 when a hose fitting came loose from the engine block causing a catastrophic loss of coolant from the engine. The failure can occur multiple times I have been told by other owners of 996 and 997 model porsche 911 model variants. Occurs in all models (carrera, turbo, gt3, gt3rs) as noted here: http://forums.rennlist.com/rennforums/showthread.php?t=592328&goto=newpost. Consequences are dumping of antifreeze on the roadway which has a potential to cause an accident. My car was fixed by porsche under warranty. Porsche replaced fittings in the block which were epoxied in as were the original fittings. A more permanent solution should be required, such as welding or pinning of the fittings into the engine case. Old parts are not available as porsche will not turn over any parts replaced under warranty.
Vehicle had complete loss of control due to a cooling system fitting coming unglued from the engine block. The coolant fitting is press fitted into place using an adhesive that failed. The entire contents of the cooling system released onto the rear tires causing a loss of control.
Coolant fitting adhesive failed, spraying coolant on rear tires, which caused the vehicle to lose control. Fitting was replaced under warranty with the same problematic adhesive. Multiple failures have been noted in porsche forums and a recently published article in a global magazine noted this issue has been around for several years with this engine type, with no resolution from porsche.
