first, have had an over heating problem was having to refill the radiator reserve everyday. but never no leaks or spills under the car. Secod replaced a coolong sensor that was said to control the fan. However the fan only works when the air conditioning is on or if the car cooling guage is showing hot. please help.

Hi there,

The cooling fan dose not run all the time, it cycles on & off this is controlled by the sensor you replaced, as for the coolant leak, have the system pressure tested as this will show up any external leaks. Start here.
