On this latest post we would like to share the 911 Coolant Pipe Fix we did on AJ’s Porsche 996 Turbo. AJ has been our customer since he got stationed in TX from Washington State and we have been taking care of his 911 Turbo.
Recently we recieved and email and he wrote his car lost abnormal amount of coolant in the matter of minutes. Car was smoking and low coolant warning light was present. We advised him not to drive the car and get it towed over to our shop.
When it arrived we got right to work.

“You may be aware of coolant pipe issues on GT1-block equipped models (GT3, GT2, Turbo), where coolant pipes come apart while driving and the rapid loss of engine coolant can cause spins/crashes at race tracks when slippery coolant sprays all over the rear tires.
The problem exists on the GT1 motor because there are a couple coolant pipes in these motors that are not a single cast piece: the larger cast pieces have extruded inlet/outlet tubes that are connected using an adhesive. There is no metal-to-metal friction or press-fit to keep these tubes in place, so after enough heat cycles the adhesive will soften/loosen up and the tube will come out of the cast block (with the hose still attached), resulting in a rapid loss of engine coolant.
Regardless of how the vehicle is driven, it seems this problem may eventually effect all 996/997 Turbo, GT2 and GT3 models including the 2010+ GT3 and GT3RS.”
Once we pulled the engine out, after some disassembling we found the source of the problem. On Oil cooler hosing bracket, coolant hoses going into the bracket came lose and cause all engine coolant to escape running over from the engine to the ground. Luckily AJ noticed this very quick, pulled over and shut off the car, saving himself and his car from major issues.
We performed a full 911 Coolant Pipe Fix using pinning method we have been favoring for years. We also replaced few worn out hoses and replaced all seals to ensure the job is done right. We have been performing 911 Coolant Pipe Fix on both turbo and GT vehicles over the years.
