2004 Porsche 911 Turbo Problems

AFTER 1 HOUR OF SLOW 880-N HIGHWAY STOP AND GO DRIVING IN TRAFFIC, A LARGE COLUMN OF STEAM WAS OBSERVED COMING FROM REAR DRIVER SIDE OF VEHICLE WHILE EXITING INTERSTATE. IMMEDIATELY OBSERVED HUGE COOLANT PUDDLE DEVELOPING ON FREEWAY OFFRAMP, AND ALERTS ON DASHBOARD GAUGES ("CHECK COOLANT LEVEL"). UPON STOPPING THE CAR IT WAS OBSERVED ONE OF THE COOLANT HOSES LEADING FROM THE WATER PUMP HAD COME LOOSE. THESE ARE HOSE FITTINGS WHICH ARE EPOXIED INTO THE ALUMINUM WATER DISTRIBUTION SYSTEM WHICH COME LOOSE OVER TIME AFTER THE EPOXY BECOMES BRITTLE WITH AGE. THE ENGINE DEPOSITED ITS ENTIRE COOLANT SYSTEM QUANTITY RAPIDLY ONTO THE EXIT OFFRAMP OF THE HIGHWAY WHICH MAY POTENTIALLY CAUSE A CRASH. THIS IS AN EXTREMELY WELL DOCUMENTED ISSUE AFFECTING GT1 BLOCK ENGINES MADE BY PORSCHE IN THE 996TT, 996 GT2, GT3, AND 997 TT VEHICLES.
