See my original first post above. Does your gauge act the same as mine with the key in different positions? Or does your gauge not move at all?

The "SENSOR" on the waterpump has absolutely nothing to do with the temp. gauge on the inst. panel. It gets it's signal from a "SENDER" on the pass. side head. There exist multiple threads on this issue already, and some of them are quite extensive in their coverage of this issue.

talked to a guy at autozone, told me theres a switch and a sender...my car just sits at C and doesn't move

i'm only speaking from limited experience but my local parts guy tried 3 different ones and none worked..i have a Delphi sitting at home waiting to be installed. i'm assuming AC delco would be good as well.

rockauto has the best parts lookup because for most parts they write OE next to the part and delphi is marked as OE for the gauge sender.

none of those parts fixed it, temp shoots to H when you start engine then back to C, my boys still looking into it but i bought a aftermarket gauge today im done with it just want to ride lol
