Man I dunno why it's getting hot unless it has air in it somehow. I've run huge motors in yjs and never had a cooling issue.

Thought I had the issue solved! I moved the fan 1" closer to the radiator , That did make an air flow increase & I could let it idle for 15 min. But it did slowly creep to the 210* mark. down the road I went to cool it down.Getting closer I guess.

Woodtic,
Did you ever resolve your cooling issue? I'm running a 383 stroker in a 87 yj having cooling issues here in Arizona. Running a 180 t stat, 3 row alum radiator. Alum shroud with an electric fan. Will get up to 210 with no problems. And it's only 90 out right now. If we run the ac, it will heat up even worse. Been banging my head. Can't seem to find a solution. Help would be great. Thanks.
