Re: 97 taurus overheating after new thermostat
Do you have access to a scan tool with a data stream function? If so, you could check the datastream for the coolant temp to determine if the guage is reporting similar to what the PCM thinks the coolant temp is. I'll check my service manual for my 1998 to see if the gauge is driven off the same sensor as the cooling fans, etc.
Is the guage stuck on hot, cold, in the middle, or where? I think open circuit the guage will read all the way cold.
