I have a coolant temp gauge problem. When it was working fine it read in the middle of the gauge, but now it is reading on the cool side ( up only one slash). I replaced a temp sensor that is located behind the motor next to the firewall on the drivers side. But it still is reading on the cool side. Any help would be great. Thanks

 

Probably a stuck open thermostat.

 

that would be my next guess. Pull it, and see if its open. while the car is cold of course

 

^^thermostat totally agree

 

I willchange it tonight and report back. Thanks for all the help

 

i have the same problem, does that have any fuel milage problems? somone told me it does.. but idk how it would effect it.. how would you go about changing the thermostat? is it difficult?

mine will read normal every other time i use my car.

 

Yes it will mess with you mileage. No, it is not a cake walk to replace the thermostat. Pretty much the same precedure as replacing the timing belt.

 

I am up and running again I was a little off on the sensors and switches. The temp sensor I changed on the drivers side of the motor is really the temp switch. The temp sensor is on the passenger side of the motor. It was the temp sensor that was bad. So I did not change the thermostat. But thanks for all the help everyone

 

yea same prob here ... it was bad but now it seems to be working again ... I am getting absolutely horrible gas millage with it messed up ... like 17 mpg highway and about 12 in the city .. its killing me ... but TB job is coming soon so itll get replaced then

these clusters have been known to have bad temp gauges which i thought was the problem at first then i thought it was the cts but it is probably the thermo
