pab95 said:The coolant temp sensor is located right in front of the thermostat housing. Based on your description of no gauge movement at all I think the sensor is the culprit. I just recently had thermostat issue myself but did not get a CEL. Temp gauge would read lower than normal at times, especially on freeway. Changing thermostat fixed it!
Looking down into the engine you can see it right in front of and beneath the battery tray. My plug is light green in color. It's easiest if you reach down from above and use your left hand to turn it. It can also be accessed from below.raymondjiii said:Thanks, I am going to give it a try this weekend. BTW: Can you tell me where the drain plug is for the radiator?
Also I noticed on the new thermostat it has a little dimple on it. (Just like on Volvos and maybe others.) It's important to get that facing the right way. I don't know which way it goes and I'm afraid the old thermostat is going to fall out and I won't be able to see it before it does.
I've got to get one of these WIS setups, where do I get it?
