God i am sick of this. Ok here is the prob, i had my temp guage spike a couple of times. The motor was hot and not the hose wasnt. Bad thermostat right? Thats what i thought so i replaced it and guess what it still does it. But not as much. It also moved the temp guage up about 20 degrees when i turned the defrost on. WTF?!! I think my sensor is ****, or some other electrical problem, what do you guys think?

 

Install an aftermarket one and see.

 

Well it fixed itself again, so i will keep ya updated if anything starts acting weird.
