thermostat replacement
 

Does any one know if I have to remove the fan before I start to wokr on replacing the thermostat?

yes you have to remove the fan and the fan cover and then remove the three small scews.

How difficult a job is replacing the termostat? Any tutorials out there?

its easy, $150 at local shop.

why are you replacing the thermostat?

how many miles?

I6 or V8?


not a lot of info to answer your question.

I had first problem with the temperature gage which points at red after the engine started for about 5 minutes. And when I re-started car, the temperature is at edge of the blue-white, too low. Clearly the water is not warmed up. I have reseted the computer,now, the gage temp lookes fine but the water temp is still not hot. the is car is 3.0 with 55k on it.

While you are in there check the water pump for leaks. My 3.0L lost the pump at 37K and the thermostat and housing were shot also.

will a thermostat staying open cause the tamp gauge to go to the red even if the vehicle hasn't been started?
