The temperature guage on our 2004 Suburban occasionally stops working and sometimes shows about 1/2 of what I would expect the temp to be.

At this point Im willing to replace the sending unit since they seem cheap enough. I'd appreciate some directions on where exactly it is located and or another suggestion as to what to look at or replace.

Thanks

Thanks! I found it. Picture is worth a 1000 words.

I checked the wires and they look ok. I was kind of hoping that I'd see some chewed wiring which would make for an easy fix.

So my next things was to replace sensor. If I unsrew and pull out the sensor will I have coolant pouring out?

Also do you have any other recomendations for things to try?
