THIS IS IN RESPONSE TO MY AWARENESS OF NHTSA PE13-009. I AM THE THIRD OWNER OF A 2004 PORSCHE GT3 THAT I USE PRIMARILY FOR TRACK DRIVING DAYS AND OCCASIONALLY FOR STREET USE. WHEN I PURCHASED THE CAR IN 2010, I WAS AWARE OF MANY REPORTS FROM OWNERS OF SIMILAR CARS THAT HAD EXPERIENCED SUDDEN COOLANT LOSS FROM ANY OF EIGHT GLUED-IN TUBE-LIKE ALUMINUM FITTINGS TO WHICH COOLANT HOSES ARE ATTACHED. THE REPORTS DESCRIBED THE CATASTROPHIC EFFECTS OF COOLANT LOSS, PRIMARILY ON THE TRACK, THAT IN SOME CASES RESULTED IN LOSS OF CONTROL TO THE AFFECTED CAR AND/OR LOSS OF CONTROL TO CARS FOLLOWING THAT CAR. A NUMBER OF CRASHES WERE REPORTED. THESE REPORTS ARE CONTAINED IN VARIOUS ONLINE FORUMS, INCLUDING RENNLIST.COM. BECAUSE I WAS CONCERNED ABOUT THE POSSIBILITY OF THIS FAILURE OCCURRING TO MY CAR, I PROPHYLACTICALLY HAD MY ENGINE REMOVED AND ALL EIGHT COOLANT PIPES WELDED INTO THE ALUMINUM MANIFOLDS THAT THEY HAD ORIGINALLY BEEN GLUED INTO. I DID THIS AT A COST OF $2500. I THINK IT WOULD BE PRUDENT FOR PORSCHE CARS NORTH AMERICA TO RECOGNIZE THE ISSUE CREATED BY THIS POOR DESIGN AND CORRECT IT BY RECALLING CARS THAT HAVE NOT BEEN REPAIRED, AND REIMBURSING OWNERS, LIKE ME, WHO TOOK IT UPON THEMSELVES TO CORRECT THE PROBLEM BEFORE THERE WERE ANY CONSEQUENCES. IT IS INTERESTING TO NOTE THAT VARIOUS SIMILAR-ENGINED FACTORY RACE CARS MADE BY PORSCHE DURING THAT ERA, INCLUDING THE 2001 GT3 RS THAT I OWN, USED A COMPLETELY DIFFERENT (AND MORE ROBUST) THREADED MEANS OF ATTACHING THESE COOLANT FITTINGS TO THE COOLANT MANIFOLD. *TR

I PURCHASED MY 2004 PORSCHE GT3 IN MAY OF 2009. IT HAD JUST UNDER 20,000 MILES ON IT. IN AUGUST, 2010, I WAS DRIVING ON TRACK AT TEXAS MOTOR SPEEDWAY AND ONE OF THE COOLANT FITTINGS CAME LOOSE FROM THE ENGINE. THE EPOXY THAT HOLDS THE PRESS-FIT COUPLER TO ONE OF THE HEAT EXCHANGERS HAD LOST ITS ABILITY TO RETAIN THE FITTING AND CAME DISCONNECTED. ALL OF THE ENGINE COOLANT WAS LOST IN A SINGLE INSTANCE. [CATASTROPHIC COOLANT LOSS]. I HAD THAT FITTING REPLACED BY THE PORSCHE DEALER IN DALLAS UNDER AFTERMARKET WARRANTY. I CAN PROVIDE INFO REGARDING THE ON THIS AT YOUR REQUEST, AND I HAVE SOME PICTURES OF THE OFFENDING PART. I HAD A SECOND (AND SEPARATE) FITTING FAIL IN JANUARY 2011 AT 35,000 WHILE DRIVING ON TRACK AT MOTORSPORT RANCH HOUSTON. THEY SAME SYMPTOMS WERE FOUND - THE PRESS-FIT COUPLING HAD COME LOOSE RESULTING IN COMPLETE COOLANT LOSS. THIS WAS ALSO REPAIRED WITH A FACTORY REPLACEMENT PART UNDER AFTERMARKET WARRANTY AT THE PORSCHE DEALER IN HOUSTON. I BELIEVE THERE ARE 8 KNOWN PRESS-FIT COUPLERS ON THE GT1 ENGINE BLOCK IN THE 996 AND 997 MODEL GT AND TURBO CARS. EACH OF THESE IS KNOWN TO FAIL BASED ON THE PRESS-FIT COUPLER AND POOR DESIGN (USE OF EPOXY ON A HIGH PRESSURE COMPONENT). I UNDERSTAND THAT THIS IS A KNOWN PROBLEM ON PORSCHE GT/TURBO CARS AND HAS BEEN DISCUSSED ON THE INTERNET (E.G. RENNLIST) FOR MANY YEARS. 25% OF MINE HAVE FAILED, AND ALMOST EVERY OTHER GT DRIVER I KNOW HAS HAD AT LEAST ONE FAIL. *TR

EXPERIENCED SUDDEN COOLANT LOSS WHILE DRIVING ON PUBLIC ROADWAY. A BONDED-IN ALUMINUM TUBE (SPIGOT) ON THE COOLANT DISTRIBUTION MANIFOLD POPPED OFF, RESULTING IN A MASSIVE, INSTANT COOLANT LOSS. THE COOLANT DUMPED ALL OVER THE REAR TIRE, CAUSING THE VEHICLE TO GO IN TO AN UNCONTROLLABLE SKID, RENDERING THE VEHICLE INOPERABLE. LUCKILY MYSELF, MY PASSENGER, AND NO ONE ELSE WAS INJURED. MY VEHICLE IS CURRENTLY AT A PORSCHE INDEPENDENT SHOP IN SEATTLE, WA WHERE THE ENGINE IS BEING REMOVED FROM THE VEHICLE TO ADDRESS THIS FAILED FITTING AS WELL AS ADDRESS ALL COOLANT LINE FITTINGS TO PREVENT FUTURE GLUE FAILURES. THE SHOP IS WELDING ALL COOLANT FITTINGS AS IT SEEMS THE FACTORY GLUE IS NOT SUFFICIENT AT HOLDING THE ALUMINUM TUBES TOGETHER. TOTAL OUT OF POCKET COST TO ME IS ESTIMATED TO BE MORE THAN $4500 FOR PARTS AND LABOR. THE FOLLOWING ARTICLE WRITTEN BY A PORSCHE TUNER DOES A VERY GOOD JOB OF EXPLAINING THE PROBLEM IN DETAIL: HTTP://SHARKWERKS.COM/PORSCHE/TECHNICAL-ARTICLES/327-THE-GT1-COOLANT-PIPE-PREVENTION-FIX-ON-GT1-BLOCK-GT3-GT2-TURBO-CARS.HTML ADDITIONAL INFORMATION ASCERTAINED FROM RESEARCH AND DISCUSSION WITH REPUTABLE PORSCHE INDEPENDENT SHOPS, RACE TEAMS, RACE SHOPS: IN THESE ENGINES, COOLANT/ANTI-FREEZE CIRCULATES THROUGH ALUMINUM CASTINGS AND RUBBER HOSES. HOSES ARE CLAMPED ONTO ALUMINUM SLEEVES THAT ARE INSERTED INTO THE BORES OF THE CASTINGS AND HELD IN WITH ADHESIVE. PROBLEM: ADHESIVE EVENTUALLY FAILS, WHICH ALLOWS THE SLEEVES TO "BLOW" OUT OF THE ENGINE, RESULTING IN A SUDDEN LOSS AND SPILLAGE OF SLIPPERY COOLANT/ANTI-FREEZE ONTO THE VEHICLE REAR TIRES AND ROAD SURFACE. THIS CAUSES AN IMMEDIATE AND DANGEROUS LOSS OF TRACTION TO ANY VEHICLE DRIVING THROUGH THE SPILL, INCLUDING THE ONE SPILLING THE FLUID. *TR

THE COOLANT LINES ON THIS CAR HAVE WELL KNOWN AND DOCUMENTED FAILURE PROBLEMS. I AM VERY CONCERNED FOR MY SAFETY AND THE SAFETY OF MY PASSENGERS AND AS SUCH AM GOING TO HAVE THE REPAIRS COMPLETED AS A PRECAUTIONARY MEASURE. WITH THE FAILURE RATE OF THE COOLANT FITTINGS ON THESE CARS, AND THE USUALLY CATASTROPHIC RESULTS I DO NOT FEEL SAFE DRIVING THIS VEHICLE. I'M GOING TO SPEND MY OWN MONEY TO CORRECT A PROBLEM THAT SHOULD HAVE BEEN FIXED BY PORSCHE. *TR
I BOUGHT THIS CAR BRAND NEW FROM PORSCHE AND ALTHOUGH IT ONLY HAS AROUND 14,000 MILES ON IT, I FEEL I MUST LIMIT USE OF THE CAR UNTIL IT GETS THE GLUED COOLANT LINES REPAIRED.

I BOUGHT THIS CAR BRAND NEW FROM PORSCHE AND ALTHOUGH IT ONLY HAS AROUND 14,000 MILES ON IT, I FEEL I MUST LIMIT USE OF THE CAR UNTIL IT GETS THE GLUED COOLANT LINES REPAIRED. I HAVE NOT HAD A FAILURE YET BUT THE RISKS OF WAITING UNTIL THAT HAPPENS ARE HIGH AND COULD EASILY GO BEYOND THE FINANCIAL ASPECTS AND RESULT IN PHYSICAL HARM TO MYSELF, A PASSENGER, OR OTHER MOTORISTS. THE PROBLEM OF CATASTROPHIC COOLANT LINE FAILURE IS WELL KNOWN WITH THIS MODEL DUE TO THE USE OF GLUE RATHER THAN MECHANICAL OR WELDED CONNECTIONS. AS AN INTERIM SOLUTION I PLAN TO RUN THE CAR WITH ONLY WATER AS THE COOLING LIQUID BUT DUE TO WINTER FREEZING TEMPERATURES IN MY AREA, THIS WILL HAVE TO BE UNDONE IN THE FALL. MY BIGGEST CONCERN IS THAT A COOLANT LINE FAILURE ON A PUBLIC ROAD AND ON A CURVE CAN LEAD TO A MULTIPLE CAR ACCIDENT FOR ANYONE FOLLOWING. *TR
EARLY COOLANT PIPE LEAKAGE AT ONE OF THE FITTINGS. UNABLE TO REPAIR WITHOUT ENGINE REMOVAL. I CHOSE TO REPAIR ALL COOLANT FITTINGS AT THAT TIME. *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.
