HELP! first thing in the mornings my 207 is saying the car engine temperature is too high and that I need to stop the car, originally I thought it was a simple Thermostat replacement. My car is still saying its over heating and that I need to stop, I ignore this as the engine is stone clod. After driving to my clients house and park up and stop using my car the fan comes on and stays on for sometime. I've replaced thermo and housing. Still having issues! Has this happened to anyone else? HELP!
