FAILURE OF FACTORY GLUED IN COOLANT FITTING CAUSED AN INSTANT DUMP OF COOLANT ONTO THE REAR TIRES OF THE CAR CAUSING LOSS OF CONTROL AND A SPIN. THIS IS A WELL DOCUMENTED PROBLEM IN ALL PORSCHE GT3'S AND PORSCHE TURBO'S AND PORSCHE REFUSES TO IDENTIFY THE DESIGN FLAW OF HAVING THESE FITTINGS GLUED TOGETHER. *TR

WHILE PARTICIPATING IN THE ONE LAP OF AMERICA IN 2012 I HAD A COOLANT PIPE FITTING (BEHIND THE ALTERNATOR) COME LOOSE CAUSING THE CAR TO DUMP ALL ITS ANTIFREEZE ON THE TRACK. 3 CARS BEHIND ME RAN INTO THE ANTIFREEZE AND HAD OFF ROAD EXCURSIONS BUT LUCKILY NO DAMAGE OCCURRED TO ANY OTHER VEHICLE. UPON FURTHER INSPECTION OF MY VEHICLE AFTER THE INCIDENT I OBSERVED ANOTHER COOLANT FITTING TO BE ON THE VERGE OF FAILURE. THESE FITTINGS ARE GLUED INTO THE ENGINE BLOCK AND AS THE CAR AGES THE GLUE IS FAILING TO HOLD THE FITTINGS IN PLACE CAUSING CATASTROPHIC COOLING SYSTEM FAILURE. I SUBSEQUENTLY HAD THE ENGINE REMOVED AND ALL OF THE FAILURE PRONE FITTINGS WELDED INSTEAD OF GLUED TO PREVENT THIS FROM HAPPENING AGAIN. *TR
ENGINE HAS PRESS FIT (AND GLUED) COUPLINGS FOR COOLANT LINES. WHEN COUPLING FAILS, THERE IS RAPID COOLANT LOSS WHICH IS A TOXIC HAZARD AS WELL AS POTENTIALLY DANGEROUS TO TRAFFIC. *TR

DRIVING IN A HIGH PERFORMANCE DRIVING EVENT ON A HOT DAY GOING AROUND A FAST RIGHT HAND TURN AND FELT THE CAR BEING A LITTLE LOOSE THEN NOTICED THE ON BOARD COMPUTER FLASHING LOW COOLANT. I SLOWED DOWN AND PULLED IN TO A SAFE PLACE TO CHECK THE MOTOR AND SAW A COOLANT J SHAPED PRESS FITTING COMPLETELY POPPED OUT AND DUMPING MASS AMOUNTS OF SLIPPERY COOLANT ON THE ENGINE AND REAR TIRES. I POPPED THE FITTING BACK IN AND SAFETY WIRED IT SO HOPEFULLY IT WILL NOT COME BACK OUT. REPLACED COOLANT FLUID WITH NEW AND BURPED THE SYSTEM. *TR

PORSCHE GT1 ENGINE PRESS FIT COOLANT COUPLING FAILURE. HIGH PRESSURE COOLANT COUPLER FAILS CAUSING RAPID LOSS OF ALL COOLANT. THIS IS NOT ONLY A TOXIC HAZARD, BUT A SAFETY CONCERN ON THE ROAD. FURTHER, LOSS OF COOLANT JEOPARDIZES ENGINE LIFE. THE GT1 ENGINE HAS 8 PRESS FIT COUPLINGS. SO FAR, 2 DIFFERENT COUPLINGS HAVE FAILED ON MY CAR. 1 ON THE HEAT EXCHANGER, AND 1 ON THE STEERING PUMP HOUSING. *TR
PORSCHE GT1 ENGINE PRESS FIT COUPLING FOR COOLANT LINES. WHEN COUPLING FAILS, THERE IS RAPID COOLANT LOSS WHICH IS A TOXIC HAZARD AS WELL AS POTENTIALLY DANGEROUS TO TRAFFIC. ALSO, WITHOUT COOLANT THE ENGINE IS IN JEOPARDY OF OVERHEATING. *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.
