MY GT3 HAS COOLING PIPE ON THE ENGINE EXTERNAL TO THE BLOCK. I HAVE READ THIS IS A SYSTEMIC ISSUE WITH THE ENGINE USED IN GT3 AND TURBOS (METZGER MOTOR). A FITTING COMES LOOSE DUE TO ADHESIVE FAILURE RESULTING I LOSS OF ALL OR MOST OF THE COOLANT FLUID. THE REPAIR REQUIRES ENGINE REMOVAL AND REPAIR OF THE FITTINGS. THERE IS SOME ISSUE AS TO THE PROPER OR BEST REPAIR APPROACH. WHAT IS KNOW IS THAT THE ADHESIVE FAILURE IS ALMOST SURE TO OCCUR. I HAVE BEEN LUCKY AS I HAVE FEW MILES ON MY VEHICLE AND HAVE NOT YET EXPERIENCED THIS FAILURE, BUT VERY CONCERNED THIS WILL OCCUR AND THE SUDDEN LOSS OF COOLANT FLUID WILL MOST LIKE RESULT IN A SPINOUT OR CRASH. EVEN IF NO ACCIDENT WERE TO RESULT, I AM OUT OF NORMAL WARRANTY, THIS FAILURE WILL SET ME BACK $1500-2000. I HAVE FOLLOWED REPORTS OF THE NUMEROUS FAILURES OF THESE FITTINGS ON 6SPEEDONLINE.COM. AS I HAVE NOT YET HAD A FAILURE, I STILL WANT TO REGISTER MY CONCERN SHOULD THERE BE A NHTSA DIRECTED RECALL TO PORSCHE. *TR
