Coolant Leaking Problems of Porsche 911 Gt3

A coolant line fitting that is epoxied into the block became suddenly and completely disconnected. The coolant all flowed out of the leak nearly instantly. The pool of coolant created a hazard for following cars and the motor needed to be shut down immediately and the car towed to a service facility.

Coolant pipes leaking after drive.

Engine coolant leak led to complete upgrade of all engine coolant fittings due to widely known problem with catastrophic engine coolant loss from sudden dislodgment of coolant fittings from engine. I have seen no fewer than three other identical models suffer such coolant loss while at speed. My repairs were done to prevent a potentially dangerous and/or costly incident from this design flaw.

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 driviers around me. Thank you. . Read more...

Coolant fittings were pinned after car started to show a small weeping leak on one of the fittings. Mezger engined 911's split the fittings and can cause rapid coolant loss and a sudden loss of traction.

Early coolant pipe leakage at one of the fittings. Unable to repair without engine removal. I chose to repair all coolant fittings at that time.

Coolant lines came loose where they were glued to the motor. I have seen catastrophic failures, and did not want to have an accident. Had the motor removed, and repair shop said some of mine were loose and showed signs of leaking. Had all welded at an independent shop. Porsche would not fix unless there was a failure, and would only re-glue those that were loose.

Paid out of pocket for preventative coolant fitting welding. The epoxy on oem coolant fittings is known to fail, potentially leaking coolant on to the rear tires or road surface behind the vehicle without warning, creating a potentially deadly scenario.
