Three problems related to power train have been reported for the 2001 Porsche 911 Turbo. The most recently reported issues are listed below.
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.
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 whils 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.
