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?

Water Pump Thermostate, etc
 

I have done a water pump , thermostate and belts on my 03 if you need advice and what to do ask me...

How difficult is it to do the thermostat?

you gauge should not goto red with key in/ KOEO

I know... but it does! As soon as I Turn the key to position 2 but don't start the car it shoots to the red. Even if it has sat for more than 12 hours.

IMHO You most likely have an electrical problem and it would be best to take it to a dealer or well equipped indy to have them troubleshoot your system. It could be as simple as a wiring short or as complex as a faulty ECM. Either way they are equipped to find the problem.

Sounds more like a problem with the sending unit then the thermostat. JMHO

FIXED!!! I reset the ecu by disconnecting the battery and holding the brake pedal down and then re-connected and its done! Thanks For all your help! You guys were great!

Awesome! Glad it's all fixed... great suggestion to fix it.

holy crap. he didn't even have to go under the hood!
