93CutlassSupreme Posted June 5, 2007 Report Share Posted June 5, 2007 3.1 Mpfi, "gauges cluster" Where is the coolant temp sensor for the temp gauge in the instrument panel? It isn't the one on the thermostat housing. Thank you. Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted June 5, 2007 Report Share Posted June 5, 2007 On the driver's side corner of the rear head. One green wire coming from it. Quote Link to comment Share on other sites More sharing options...

Lee Posted June 15, 2007 Report Share Posted June 15, 2007 I changed mine out when I put in the UB3 dash and I didn't need to move the motor. "Feel the Force Luke" No need to see it. Quote Link to comment Share on other sites More sharing options...

You have a 3800 don't you Lee? It's kinda tough to get to where the coolant temp sender is on the 3.1's without rotating the engine. I tried before and just ended up tilting the engine since I could hardly get my hands back there with all the crap in the way. Quote Link to comment Share on other sites More sharing options...
