Over heating?

[Russ Hood]

I have the 26 inch radiator in my 440 car. Everything except the radiator is new and it seems to overheat. I had it overheat yesterday climbing elevation and it was coming out around the cap, replaced the cap. But when regular driving it goes over to the right and then comes back to normal, like it takes awhile for the thermostat to open.

Thoughts?

Ocerheating while driving usually indicates a lack of airflow, So I would guess that maybe your radiator support to hood seal is not in place, or the cowl seal to hood seal is missing. Or maybe you are not running the clutch fan and shroud?

Tell us more about the cooling system, fan and what speed and gear were you climbing at ?
