I've got some questions about my temp gauge on my '83 C10. I have a new Crate engine, and it voids the warranty if the gauge doesn't work. I took it to an auto-electric company to make sure the gauge was working correctly. Of course, the place tried to sell me on digital gauges. It would be nice, but that's not in my budget!
But I did buy a new temp gauge, and they checked it out and it was functioning well. HOWEVER, the other day it went all the way hot, and stayed there. Since that time it has come back a little, but nowhere in the "normal" zone. Should I be worried? Do I have a ground issue? Thoughts? Thanks!
