IllustrationDUE TO HIGHLIGHTED PROBLEMS WITH THE COOLING SYSTEM (NAMELY THE FITTINGS POPPING OFF) ON THE 2005 PORSCHE 911 GT3 IN VARIOUS FORUMS AND WEB SITES. I HAVE DECIDED TO PERFORM PREVENTATIVE MAINTENANCE AND TO ALLEVIATE SAFETY CONCERN WITH THE COOLING SYSTEM (FITTING AND HOSES) TO WELD THE COOLANT CUPLINGS. *TR

I WAS DRIVING ON A SATURDAY NIGHT ON INTERSTATE 79 NORTHBOUND AT APPROXIMATELY MILE MARKER 3 BETWEEN MINK SHOALS AND ELKVIEW, WV. I HAD JUST PICKED UP A PIZZA AND I WAS HEADED HOME A FEW MILES FROM MY HOUSE. I WAS GOING UPHILL WHEN I HEARD A POP AND SAW A HUGE PLUME OF STEAM SHOOT OUT FROM BEHIND MY CAR. I THEN TAPPED THE BRAKES AND THE REAR RIGHT TIRE GOT A LITTLE LOOSE AS IT HAD ANTIFREEZE COOLANT SPRAYING DIRECTLY ON IT. I MANAGED TO GET MY CAR HOME AS IT WAS QUICKLY STARTING TO GET HOT AND CLOSE TO OVERHEATING AS THERE WAS NO COOLANT LEFT. I GOOGLED "PORSCHE 911 COOLANT LINE FAILURE" AND QUICKLY LEARNED THAT MY ISSUE HAD HAPPENED TO MANY OTHERS.I LEARNED THAT FROM THE FACTORY PORSCHE GLUES/EPOXIES THE COOLANT FITTINGS INTO THE ENGINE BLOCK AND OVER TIME AND MANY HEAT CYCLES LATER THE GLUE/EPOXY FAILS AND THE COOLANT SPRAYS EVERYWHERE AND MANY TIMES DIRECTLY ON THE REAR TIRES. THIS CREATES AN UNSAFE ENVIRONMENT FOR THE DRIVER AND PASSENGER AND ANYONE IN THE IMMEDIATE VICINITY. I PERFORMED A QUICK FIX ON MY CAR AND PINNED THE FITTING BACK INTO THE BLOCK. I LATER LEARNED THAT THE ENTIRE ENGINE HAD TO BE DROPPED AND EACH OF THE 6 COOLANT LINES NEEDED TO BE WELDED TOGETHER TO TRULY PREVENT THIS FROM BEING A HAZARD. I PAID SEVERAL THOUSAND DOLLARS TO HAVE THE ENGINE DROPPED AND FIXED LIKE PORSCHE SHOULD HAVE DONE FROM THE FACTORY. THEY SHOULD HAVE ADDRESSED THE ISSUE AND OFFERED TO FIX THE FAILED COOLANT LINES UNDER A RECALL BUT TO MY KNOWLEDGE THIS HAS NOT BEEN DONE. PORSCHE CLAIMS NO FAULT OF THEIRS. MANY PERFORMANCE DRIVING EVENTS HAVE IDENTIFIED THE ISSUE AND WON'T LET YOU DRIVE YOUR CAR AT THEIR EVENT UNLESS THE ISSUE HAS BEEN PROPERLY ADDRESSED BY DROPPING THE ENGINE. WHEN YOU SPEND THAT MUCH MONEY ON A CAR OR ANY MONEY FOR THAT MANNER YOU EXPECT THE CAR MANUFACTURE TO DO EVERYTHING POSSIBLE TO KEEP YOUR SAFETY AND THE SAFETY OF OTHERS A HIGH PRIORITY. *TR

1PE13009 · Rapid Coolant Loss
Opened Apr 26, 2013 · Closed Mar 10, 2014
Status: closed (inferred from source dates) · Engine And Engine Cooling; Engine And Engine Cooling:cooling System; Engine And Engine Cooling:cooling System:hoses/lines/piping/fittings
On April 26, 2013, the Office of Defects Investigation (ODI) opened PE13-009 to investigate 10 complaints alleging incidents of sudden coolant loss while traveling on public roadways in certain model year (MY) 2001 through 2007 Porsche 911 vehicles.The complaints alleged that pipe ends joined by epoxy to certain cooling system components may fail suddenly and separate, resulting in large volumes of coolant leakage.The investigation was opened to assess evidence of a design or manufacturing defect in the coolant pipe fittings and any related safety consequences. In response to ODI?s Information Request letter, Porsche identified a manufacturing quality issue with the supplier?s application of adhesive to coolant pipe fittings that resulted in elevated failure rates in approximately 6,800 early production 997 generation vehicles (MY 2007 and early MY 2008).ODI?s analysis of field data showed that the age-adjusted failure rate for these vehicles was approximately six times greater than MY 2001 through 2005 996 generation vehicles and MY 2008 through 2011 997 generation vehicles built after a process improvement for adhesive application was implemented by the supplier.Most of the leak complaints reviewed by ODI did not appear to involve complete separation of the fittings and many were detected when the vehicle was parked.There were no crashes or injuries reported to be related to the alleged defect in any of the subject vehicles.ODI identified two allegations that coolant leakage resulted in loss of control incidents, but neither involved vehicles affected by the assembly process quality issue.A third loss of control allegation involving a vehicle built during the period affected by the supplier process concern is not counted since ODI was unable to contact the owner to confirm the incident.See the full closing resume in the document file for PE13-009 for additional information about the subject cooling system and ODI?s analysis of field data related to the alleged defect. A safety-related defect has not been identified at this time and further use of agency resources does not appear to be warranted.Accordingly, this investigation is closed.The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist.The agency will monitor this issue and reserves the right to take further action if warranted by the circumstances.
