This is a 1980 258 inline 6 with a new radiator, water pump, and thermostat installed. New coolant as well. It's getting so hot the paint is peeling off the header -- anyone have any suggestions? Not sure what's causing it, as everything has been replaced; I'm out of ideas!
Thanks for any input,

did you replace the hoses as well. i've seen the bottom hose get so soft that it will squash down flat when you're on the gas. looks normal at idle. how about timing? paint usually does peel off the header. they get pretty warm. do you have a temp gauge to know how hot its actually running at?

How about your fan clutch. After warming up the engine, you should not be able to just spin the fan, if you can the clutch is shot. Also, this might be a dumb question, but did you check your coolant level after changing in. Air lock is common when refilling, then when it cools off the air bleeds out and the coolant level is WAY down.

What do your gadges show. Do you have any aftermarket gadges. Any other over heating simptoms pinging, desieling. If all you are going off is the paint on hte headers I would tend to tink you have no problem. Headers get very hot.

How about the fan shroud? Are you running one? Is it in good shape? My quickey homemade one worked but not very well. I got a new one from the dealer and it fixed my overheating problems. Don't let them BS you, they still make them for CJs, about $75.
