Hi everyone. My 1997 a6 c5 2.4 starts overheating right after 3-5mins I start the car. What can be the reason for that ? It suddenly happened when I was driving home I haven't driven the car since then. I Was suspicious about the gasket at first but I haven't driven the car when it was over heating so why should the gasket be blown ? I am suspicious about thermostat or waterpump. Does anyone have any idea or anything like that happened ?
