4th Generation MJ project

Made it. Slow driving. Could only hit 60. Any more I'd over heat. The hills made it heat up to red line too. Had to pull over a few times. Had an idea to prop the hood open with a stick then strap it down so more air could get in. Didnt over heat again but it was still high.

FWIW, the overheating issue in my 89 was the radiator. I went from a closed loop system to a Mishimoto open loop radiator with a 2.5L Renix overflow tank and I haven’t had an issue since—never even exceeds 210. It could just be that the radiator has some corrosion in it not cooling effectively.
