With all the problems I had with a seemingly overheating issue, I was finally able to get the temperature gauge to work correctly. After doing everything in the world, I figured I would just put the old temperature sender (not sensor) back in (the one to the left of the themostat housing with one metal prong) With the new one in, the temp. gauge was showing around 220-225. Now, with the old one in, the gauge is 180, exactly where it is supposed to be. Let me know if the picture looks right. I let the truck run a solid 15 minutes and it would never go passed that.
