I have a rebuilt (Supposedly) 1966 with a 289ci.
It has a new 3 tier radiator, radiator cap, and functional water pump. No air conditioner.
I had a problem where radiator fluid would leak out from different places. My mechanic told me I had the wrong radiator cap which was rated to high on preassure. He placed a new cap in place and this seemed to solve my problem but, when driving in hot weather my radiator fluid expand and over flows the overflow container (just installed). I do not know if the fluid ever goes back to the radiator or not. Should I remove the thermostadt?
It tends to overheat when I slow down and stop to get gas.
Any suffestions will be appreciated.
