Do you happen to have an OEM part number as well? When I checked a few parts places, they couldn't do anything without the OEM number.. A few others had the coolant sensor for anywhere from $14-$25. If that's the right sensor, then I figure that's and easy enough thing to do

Mine was the sensor that is found in the engine compartment, not the coolant temp sensor. It sits in a rubber gromet that is snapped in the "spider" on the passenger side of the engine compartment. I can get a part number for the '00 model off of it when I get home if you still need it.

My temp gauge light went off after I had some body work done on the car, dust from the work done must have gotten in the engine compartment, and caused the engine sensor to malfunction. A little cleaner fluid spray and it was good to go....I also had the problem with the temp sensor with the coolant tank when the hose was leaking. I remember mine going off in this instance when the coolant got somewhere a bit below the minimum line, so like PorscheDoc said, you're right at the point where the temp gauge light should be going off.....

Yes, the part no would be great. I have checked the coolant levels, and that does not appear to be the issue... Refilled the coolant and its not dropping, but the light still comes on, and I don't hear the engine compartment fan running. Intermittently, the fan does work... At those points, the light does not come on.

My other thought was a relay, so I replaced that, and the light stayed off for 2 days, so I figured that it may be a loose wire / connection. I checked all of those, and they appear to be good... Next step is to replace the sensor.

Thanks!
