2001 Porsche 911 Turbo Engine Problems

COOLANT PIPES COME APART WHILE DRIVING AND THERE WAS RAPID LOSS OF ENGINE COOLANT. THE PROBLEM EXISTS ON THE GT1 MOTOR BECAUSE THERE ARE A COUPLE COOLANT PIPES IN THESE MOTORS THAT ARE NOT A SINGLE CAST PIECE: THE LARGER CAST PIECES HAVE EXTRUDED INLET/OUTLET TUBES THAT ARE CONNECTED USING AN ADHESIVE. THERE IS NO METAL-TO-METAL FRICTION OR PRESS-FIT TO KEEP THESE TUBES IN PLACE, SO AFTER ENOUGH HEAT CYCLES THE ADHESIVE WILL SOFTEN/LOOSEN UP AND THE TUBE WILL COME OUT OF THE CAST BLOCK (WITH THE HOSE STILL ATTACHED), RESULTING IN A RAPID LOSS OF ENGINE COOLANT. ....UPDATED 04/25/16 *BF

WHILE DRIVING ON THE HIGHWAY A CATASTROPHIC FAILURE OCCURRED IN THE COOLANT SYSTEM. ONE OF THE ALUMINUM HOSE FITTINGS THAT IS EPOXIED INTO THE ALUMINUM HOUSING BROKE FREE CAUSING ENGINE COOLANT TO EMPTY OUT OF THE ENGINE ONTO THE HIGHWAY IN A MATTER OF SECONDS. THE RUBBER HOSE DID NOT FAIL AND IT WAS STILL CONNECTED TO ALUMINUM HOSE FITTING THAT BROKE AWAY FROM THE HOUSING. I PULLED THE CAR OFF THE FREEWAY IMMEDIATELY TO PREVENT FURTHER DAMAGE TO THE CAR. FURTHER INSPECTION AT THE DEALER SERVICE CENTER SHOWED THERE WAS VERY LITTLE TO NO COOLANT LEFT IN THE ENTIRE SYSTEM. *TR

I HAVE BEEN INFORMED BY MY PORSCHE TECHNICIAN THAT PORSCHE USED AN INFERIOR AND MECHANICALLY POOR DESIGN FOR THE ENGINE COOLANT LINES. THEY ARE GLUED TOGETHER IN A PLACE WHERE THEY GET HOT. AFTER SEVERAL HEAT CYCLES, THEY WILL FAIL. ALL CARS WITH THIS ENGINE DESIGN WILL HAVE THIS FAILURE OVER TIME. IF THE COOLANT LINES FAIL WHILE THE CAR IS MOVING, THE SLICK COOLANT CAN GET ON THE TIRES AND CAUSE AN ACCIDENT. ALSO, THE ENGINE CAN OVERHEAT WITH A REPLACEMENT COST OF OVER $20,000. PORSCHE IS AWARE OF THIS, AS THEY HAVE USED A SUPERIOR THREADED DESIGN ON THEIR RACE CARS WITH THIS ENGINE. I HAVE BEEN ADVISED THAT THIS WILL TAKE THOUSANDS OF DOLLARS TO FIX, AND THE CAR WILL BE OUT OF SERVICE FOR WEEKS. *TR

I WAS ACCELERATING UP TO HIGHWAY SPEEDS (65 MPH) ON A ON RAMP WHEN I HEARD A POP UNDER THE CAR. I FELT THE CAR SHAKE AND DECIDED TO PULL OVER. I DISCOVERED COOLANT LEAKING FROM UNDER THE CAR AND THE SHAKE WAS CAUSED BY MY REAR TIRES SLIPPING AND TRACTION CONTROL COMPENSATING FOR ACCELERATION UNDER SLIPPERY CONDITIONS. LUCKILY I DIDN'T LOOSE CONTROL AND CRASH INTO ANOTHER PERSON THAT MAY HAVE CAUSED INJURY OR DEATH TO THEM OR MYSELF. THE COOLANT PIPING IS A WELL KNOWN PROBLEM WITH THIS YEAR MODEL CAR, IT IS ONLY SECURED BY A GLUE LIKE SUBSTANCE NOT CLAMPED, IT SEEM THE GLUE LET GO AND CAUSED A PRESSURE RELEASE IN MY COOLANT SYSTEM. *TR

I WAS DRIVING THE CAR WHEN SUDDENLY THE LOW COOLANT LIGHT CAME ON. INSTANTLY, TEMPERATURE STARTED RISING AND I SHUT IT DOWN. I WASN'T SURE WHAT WAS WRONG BUT I FOUND COOLANT ALL OVER THE REAR WHEELS AND TIRES. AFTER SITTING ON SIDE OF ROAD, ANOTHER PORSCHE OWNER STOPPED BY. WE THOUGHT THE CAR WAS JUST OVERHEATING, SO WE ADDED WATER. IT SEEMED FINE SO I STARTED DRIVING HOME AND THEN IT HAPPENED AGAIN. WE PUT THE CAR ON MY BUDDY'S LIFT AND IDENTIFIED THAT THE COOLANT WAS LEAKING FROM THE TOP OF THE MOTOR. AFTER DOING SOME RESEARCH AND TALKING TO MY MECHANIC, IT APPEARS THAT THE COOLANT HOSES THAT ARE BONDED TO THE EXCHANGER HAVE SEPARATED. APPARENTLY, THE HOSE IS GLUED TO THE FITTING. THEY ARE BOTH METAL. MY MECHANIC IS STILL TRYING TO IDENTIFY A PERMANENT FIX BUT AS OF YET WE HAVEN'T FIXED IT. I AM WAITING A BIT TO FIGURE OUT THE BEST WAY TO FIX THE CAR TO AVOID FUTURE FAILURE. THE CAR HAS LOW MILES AND I AM CONCERNED AFTER DOING SOME RESEARCH THAT IT COULD HAPPEN AGAIN. *TR

FIRST I NOTICED A BURST OF WHITE SMOKE COMING OUT OF THE REAR, AND AFTER THAT, ENGINE TEMPERATURE START TO GO UP. SINCE I HAVE VERY CLOSE TO HOME, I JUST CRUISE BACK. *TR AFTER INSPECTION AT MECHANIC, COOLANT HOSE HAS FLY OFF ITSELF AND CAUSING ALL THE ENGINE COOLANT LOST. REPAIRING IT COSTS ME 5000+ AS IT REQUIRES DROPPING THE ENGINE, MANY HOURS OF LABOR AND 2 WEEKS WITHOUT THE CAR.

MY CAR SUFFERED A CATASTROPHIC LOSS OF COOLANT AT HIGHWAY SPEED. I WAS DRIVING AND SUDDENLY A PLUME OF SMOKE APPEARED IN THE REAR VIEW MIRROR. I THOUGHT THAT MY ENGINE HAD BLOWN AND I PULLED THE CAR OFF OF THE ROAD. TURNS OUT THAT SMOKE WAS ACTUALLY STEAM! I HAD THE CAR TOWED TO AN INDEPENDENT SHOP WHERE THEY DIAGNOSED THE PROBLEM AS THE WATER CONSOLE FITTINGS HAVING BLOWN OUT. THEY EXPLAINED TO ME THAT THESE FITTINGS WERE HELD INTO THE CONSOLE WITH AN EPOXY FROM THE MANUFACTURER, AND THAT THE EPOXY EVENTUALLY FAILS. FORTUNATELY, I WAS GOING STRAIGHT WHEN THE COOLANT ESCAPED OR THE RESULT MIGHT HAVE BEEN MUCH WORSE. THE SHOP REPAIRED MY CONSOLE BY REPLACING THE FITTINGS AND ALUMINUM WELDING THEM IN PLACE SO THEY COULD NOT FAIL AGAIN. THEY HAD TO LOWER THE ENGINE TO DO THIS. THEY ALSO TOLD ME THAT THERE WERE A COUPLE OF OTHER FITTINGS THAT WERE SIMILARLY EPOXIED IN PLACE ON THE TOP OF THE ENGINE THAT SHOULD BE WELDED TOO. THEY SAID THEIR EXPERIENCE HAS BEEN THAT FAILURES OF THOSE UPPER ENGINE FITTINGS HAVE BEEN LESS COMMON. I OPTED TO NOT HAVE THOSE FITTING WELDED AT THAT TIME AS THE SHOP WOULD HAVE HAD TO COMPLETELY REMOVE THE ENGINE AT CONSIDERABLE ADDITIONAL EXPENSE. THEY RECOMMENDED I HAVE THEM WELDED IF EVER THE ENGINE WAS REMOVED FROM THE CAR. *TR

FACTORY PORSCHE COOLANT FITTINGS FAILED AND RELEASED FROM ENGINE BLOCK. DUMPED COOLANT OVER REAR TIRES. OEM COOLANT FITTINGS ARE GLUED INTO THE BLOCK AND FATIGUE OVER TIME. THEY SHOULD BE WELDED OR THREADED INTO BLOCK TO PREVENT SAFETY ISSUES. CAR WOULD HAVE LOST TOTAL CONTROL IF TRAVELING AT HIGHWAYS SPEEDS. *TR

I WAS TOLD BY SIMILAR OWNERS LIKE MYSELF THAT THE 996 AND 997 PLATFORMS COOLANT HOSE RUPTURE DUE TO BEING GLUED FROM THE FACTORY. I HAVE OWNED THE CAR SINCE IT HAD 19,000 MILES AND MY CAR HAD 85,000 MILES AND I HAD NOT HAD AN ISSUE SO I WAS NOT SURE HOW TRUE IT WAS. ON SEP 29, OF 2012 I WAS DRIVING DOWN THE HWY WITH MY BROTHER WHEN I NOTICED WHITE SMOKE COMING FROM THE BACK OF MY VEHICLE. I PULLED OVER AND WENT TO THE BACK OF THE MOTOR AND THE COOLANT HOSE NEAR THE ALTERNATOR HAD POP OFF DUE TO THE GLUE NOT HOLDING ANY LONGER. I'M GLAD THAT NO ONE WAS HURT, BUT I'M AFRAID OF THE POTENTIAL DAMAGE THE COOLANT LEAKING IF I WOULD HAVE BEEN ON A HIGH RISE RAMP, ON THE HIGHWAY WHERE IT COULD HAVE POTENTIALLY A DEATH TO MYSELF OR PEOPLE FOLLOWING BEHIND ME. I HAVE SINCE TALKED TO A FEW OTHER PORSCHE OWNERS AND THEY ALL SEEM TO KNOW MANY OTHER OWNERS WHOM HAVE HAD THIS ISSUE. SOME ACTUALLY DAMAGING OTHER'S PROPERTY DUE TO SPIN OUT'S BECAUSE OF THE SLIPPERY COOLANT. SINCE THEN I HAVE TAKEN PRECAUTION AND HAD A FITTING WELDED IN PLACE, AND CLAMPED ON. I BELIEVE THE FACTORY SHOULD HAVE ADDRESSED THIS ISSUE AND DONE IT CORRECTLY VS GLUING A COOLANT HOSE. *TR
