2000 c70 Fan

Post by hvymtlc5 »

Just changed the radiator out and the fan is acting up. Comes on the minute I turn the car on (sometimes) and will run with A/C on or off. I also noticed that it is running when I shut the car off all the time and it didn't do that before (AC is still off). It will shut off on its own. Just don't know what happened to make it sporadic now. ideas what to check?

A bad ECT (Engine Coolant Temperature) sensor causes exactly the symptoms you describe. It is SOP to change the thermostat at the same time.
