hi, i have a 1992 corolla dx with 182000 miiles on it. i am having problems with my temp gauge( on the tach cluster if that makes a difference), the guage is reading that i am over heating when i first start the car after it has been running, and i kno its not over heating i can lean on the radiator, now after a few mins of running the gauge will drop down and act normal? i am so confussed i replaced the sensor and its a new gauge.....any ideas on what it could be? does it have two sensors or a relay i dont know about since its only doing it when i start it from a warm start? any help would be greatly apprecaited....thxs

There are 2 coolant sensors. I cannot remember exactly what the 2nd one does. One is small, the other is larger. They screw into the same area and also if there is an air pocket the sensor will give a false reading. Make sure if you replaced a sensor, make sure it was the correct sensor. BTW, these sensors are not cheap.
