Once my fan turns on it stays on untill i shut the key off, then once it warms up to temps again it comes on and stays on until i shut the key off it has done this sense new. not to bad with the rad on the rack though but think its time to fix it makes it hard for the motor to stay at a good temp when the fan is always cooling it back down..
think it might be the sensor in the rad doing it.?

The temp sensor is the switch for the fan and they go bad from time to time.
