You might want to pull the t-stats, disconnect the hoses and fan belt, then run and look for bubbles inside the thermostat housings. Something isn't right if it runs 180 without the 180 T-stats and heats with them in, maybe an internal crack or leaking head gasket.

Maybe start with testing the T-stats in a pot of water to see if and at what temp they are opening up???

Yeah, I am fairly certain it's a t-stat issue. I am going to run it without them for the summer and revisit installing them in the fall. I am done with antifreeze clean-up and gasket scraping for the time being.

Brake light switch

I have had difficulties with the re-pop switches, I keep on in the glove box just in case. Also I have had the lights stick on when the brakes were to hot one time, being new there was little room for expansion to the drums. I was using DOT 5 brake fluid which does not handle heat as well as the others. Changed that out and the problem was solved.

Sweet Success

I drove the truck to a car show for the first time yesterday. It was about 20 miles away from home on a sunny 85 degree day. Absolutely no issues on the way there or home! I won a trophy! I need to find a shut off valve to put on the block for the heater. It would have been a much more enjoyable drive without the heat in the cab from the heater.

Congratulations! You must have been sweating bullets with that heater circulating.

I'm feeling the same pain about having a seemingly cursed truck. I keep telling myself that if it was easy, I wouldn't be learning anything. You've done an amazing job with yours - WOW!

Thanks for the link! I am ordering it today. Looks like I will be draining the radiator once again. Wish I would have thought about getting the shut off a month ago. Hindsight is 20/20.

You're welcome and yes, I have to do the same thing.
