ALUMINUM COOLANT TUBES WHICH APPARENTLY ARE GLUED TOGETHER VIA THE OEM FACTORY BECOME OLD AND BRITTLE AND BLOW APART. COOLANT IS THEN POURING OUT OF THE ENGINE AT A HIGH RATE INTO THE CITY STREET. IN MY CASE, I WAS SITTING AT A RED TRAFFIC LIGHT WHEN THE COOLANT PIPE BURST/SEPARATED. IN ORDER TO FIX/REPAIR THE ISSUE, THE ENGINE MUST BE REMOVED FROM THE VEHICLE AND THE 8 COOLANT TUBES MUST BE WELDED AND/OR DRILLED AND PINNED TO KEEP THE ISSUE FROM HAPPENING AGAIN

THERE WAS NO INCIDENT, BUT THERE IS A COOLANT SMELL WHICH REGULARLY HAPPENS AFTER A LONG DRIVE. MY MECHANIC TOLD ME THAT THIS IS BECAUSE THE COOLANT FITTINGS WEEP; I'VE FOUND MANY FORUM POSTS, AND WAS TOLD BY MY MECHANIC THAT THE LINES BURSTING AND/OR SPILLING IS COMMON IN 996 TURBOS ('01-'05). HE ADVISED ME THAT I SHOULD HAVE PREVENTIVE WELDS TO MAKE SURE THAT THE COOLANT LINES DO NOT UNSEAT AND SPILL ALL OF MY COOLANT. I WAS TOLD THAT IT COULD HAPPEN TOMORROW, OR COULD HAPPEN 50K MILES FROM NOW; EITHER WAY, I WOULD BE STRANDED WHEREVER I WAS. THE WORK TO COMPLETE THE PREVENTIVE MEASURE WAS QUOTED AROUND $5-6K, BUT I HAVE NOT HAD IT COMPLETED. *TR

I OWN A 2002 911 CARRERA TURBO, WHICH HAS A WELL-KNOW AND DOCUMENTED DESIGN DEFECT IN THE ENGINE (GT1 MOTOR). IT IS KNOW AS THE COOLANT-PIPE FAILURE ISSUE. WHILE MY CAR HAS NOT YET SUFFERED A FAILURE, THERE IS A REASONABLE PROBABILITY THAT THE COOLANT PIPES MAY FAIL DURING REGULAR USE, CAUSING A SUBSTANTIAL LIKELIHOOD OF PROPERTY DAMAGE AND PERSONAL INJURY TO MYSELF AND OTHERS UTILIZING THE PUBLIC RIGHT-OF-WAY. IT IS A CLEAR SAFETY ISSUE THAT MUST BE ADDRESSED BY WAY OF RECALL AND REPAIR. THERE IS A KNOWN SOLUTION TO THE PROBLEM. HERE IS A HYPERLINK TO ONE OF THE SOURCES OF INFORMATION FOR THIS ISSUE.

PE13009 · 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.
