MY 911 TURBO SUFFERED A COOLANT SYSTEM FAILURE, AS HAS BEEN WELL DOCUMENTED FOR THIS PARTICULAR ENGINE, THE GT1 3.6 LITER IN THE 2001-2007 TURBO, GT2 AND GT3. I WAS DRIVING ON THE HIGHWAY WHEN I NOTICED SMOKE COMING FROM THE REAR OF THE CAR. UPON PULLING TO A STOP THE CAR HAD DUMPED MOST OF ITS COOLANT. IT WAS FLAT-BEDDED TO THE DEALER AND THE STEEL COOLANT PIPE HAD PULLED OUT OF THE ALUMINUM WATER SOCKET/CROSS OVER TUBE ON THE DRIVER'S SIDE OF THE ENGINE. THEY DRAINED THE COOLING SYSTEM, REPLACED THE WATER SOCKET AND ASSOCIATED SEALS AND FILLED AND BLED THE COOLING SYSTEM. THE FAILURE RESULTS FROM THE USE OF EPOXY TO ATTACH THE COOLANT PIPE TO THE SOCKET INSTEAD OF A HARD-THREADED DESIGN LIKE PORSCHE USES ON THE RACE VERSION OF THIS ENGINE. THIS FAILURE WILL OCCUR AGAIN IN THE FUTURE, AS THE REPAIR USES THE VERY SAME EPOXY, AT WHICH TIME I AM LIKELY TO BE OUT OF WARRANTY AND SEVERAL THOUSAND DOLLARS. *TR

AT A DRIVER EDUCATION EVENT IN KENT, WA, A PORSCHE TURBO HAD A FAILURE IN THE COOLANT FITTINGS THAT CAUSED THE CAR TO DUMP ALL OF ITS COOLANT ON THE PAVEMENT. I WAS BEHIND THE CAR IN A PORSCHE GT3 AND UPON DRIVING OVER THE COOLANT LOST TRACTION AND TOTALED MY CAR. THE SPEED OF THE TURBO AT THE TIME OF FAILURE WAS APPROX 90 MPH, THE CAR CONTINUED TO ACCELERATE DOWN THE STRAIGHT-AWAY AFTER THE FAILURE BUT STOPPED AFTER REALIZING THE CAR WAS SMOKING. THIS IS A COMMON ISSUE WITH THE 996 SERIES, MORE COMMONLY IN THE GT3 THAN THE TURBO. THIS IS WELL DOCUMENTED IN FORUMS SUCH AS RENNLIST.COM. HTTP://FORUMS.RENNLIST.COM/RENNFORUMS/SHOWTHREAD.PHP?T=679777&REFERRERID=108168. I HAVE HEARD OF A PCA CHAPTER THAT HAS REQUIRED THAT CARS ON THE TRACK RUN WITH WATER WETTER OR FIX THIS ISSUE WITH GETTING THE FITTINGS WELDED. GIVEN THE NUMBER OF INCIDENTS AND THE DAMAGE TO CARS EXPERIENCING THIS FAILURE AND THE CARS AROUND THEM, SOMETHING MUST BE DONE TO ADDRESS THIS. ESPECIALLY SINCE TURBOS
