“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. …”

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. …”
