1998 GLT-70 coolant fan runs continually

coolant fan does not shut off until the temp gauge goes to 0, then it will turn off after car has been shut off and siting for awhile. Last year I replaced he thremostat and temp has been running normal at mid gauge (not overheating).

I disconected the e-plug attached to fan shrould, which shut off the fan, but the motor developed a high idle, so I reconnected for now.

Is this the temporature sensor, if so where is it located?

thanks All.

Yes, it does sound like the temp sensor- it's located at the base of the thermostat housing- facing the radiator...it has 2 wires running out of it. Just make sure the connector is clean first before replacing it- but what you describe is typical when it goes bad.

Thanks MIJ, I'll check the connections before replacing.

What if you replace the sensor in the therm. housing yet the problems persists? As soon as I start my 2000 S70 the fan begins to click on then off continuously.

Is your A/C on?

My ac is usually on all the time. I keep everything on auto, and the temps here in southern AZ are mostly warm.

Your problem sounds more like a low refrigerant level in the A/C system. Anytime the A/C compressor is running the radiator fan should kick on. If the compressor is cycling due to a low charge the fan will cycle as well.

Ok I put a can in and nothings really changed. The pressure (level) was good. Do you think I may need another can? The fan is still running after I shut the car off too especially now that were getting into the upper 90s....

Thanks
