SOURCE: TEMP GUAGE JUST QUIT WORKING.

your gage has just gone out and needs to be replace. the computer control the fan. so as long as the temp sensor is connected to the engine it will work fine but you will not know the temp of your vehicle.

Cooling fan relay location


What year is the vehicle ? The cooling fan relays have nothing to do with the temp. gauge . GM had problems with the stepper motors inside the instrument cluster . Hooking up a professional scan tool to check what the PCM - engine computer is seeing from the engine temp sensor . You have duel cooling fans controlled by three relays . Checking to see what the actual engine temp. would be the first step , checking to see if the scan tool can control the cooling fans .
Look on youtube at videos on gm instrument cluster stepper motor problems

Temp guage works erratic


It sounds like you have an air lock in the coolant system . loosen of a high point hose and let the air out while keeping an eye on the water level in the radiator.. engine temp sensor will only send a signal to the CPU to adjust the fuel mixture and turn the fan on. It is not a temp gauge sender unit.

Put a new evaporator in 1995 camry temp gauge went up above normal


If the engine temp exceeds the limit the computer can kill the ac. If the cooling fan stops working the engine temp can go up and also stop the ac from being cold.
Do you know if the cooling fan is working when the problems happen ?

1992 olds cutlas 3.3litre a/c clutch comes on and off continuiously weather a/c is called for or not on the dash.engine cold or hot. rad fan also comes on when engine is cold and hot keeps cycling. when...


ok the ac will cycle even if its not on thats the way the factory has it set up.
the fan will also cycle the same way. but the temp of the motor has to do with
the thermostat thats whare i would be looking the thermostat may be bad
when you pick up a new one test it if it says 180 deg. that is when its wide
open check it with a temp guage a house hold type in a pot of boiling water
on your stove i have found 1 out fo 6 would be good go figure.
now the censors. one wire tells you temp guage 2 wires tells you its a
switch for the fan while the motor is running use the same house hold
guage a meat thermomiter will work just fine

i hope this helps you BOB !!!

Cooling fan not working


The fans only run when the engine reaches approxminatly 235 degrees F. on the guage that is near the end of scale just before guage show "HOT" I don't think you have a problem, allot of folks out there don't know about this.
