sometimes the radiator fan stays on after the car is parked, then the car will not start back up , it needs time. So my thought is that there must be some safety to keep the car from starting when the radiator fan is running because the fan is running to cool of a car that may be overheating...but the temp gauge is reading 1/4-1/2...ssoooooo relays, switches, anybody have any ideas? Iv'e already checked the coolant level.
