92 Merc topaz, 4 cyl, over 200k.
recently replaced thermostat. Fan on radiator has not been working. While warming up engine to finish filling radiator after thermostat replacement, I unpluged the Coolant tempature sensor from the thermostat housing and the fan turned on. It has not ran in over 9 months.
How to I determine if the tempature sensor is working correctly? IS what happend a good indication that the sensor needs replacing? I have to do this repair on the cheap, as I am out of work, due to an accident at work.
have the same problem?
