Q: Overheating Engine
I just recently purchased a 1967 bird with a 400 and an automatic tranny. It needs some work but for the most part is all original. The motor has 670 heads and is a YT.
It seems to over heat when sitting still. When I am driving it runs about 180 but if I sit still very long it heats up rather quick. I replaced the water pump and put a 165 thermo in it. The radiator seems to be circulating any suggestions?
A: The overheating could be several things: Poor or no coolant, Improper coolant level/mix, bad fan clutch (check hot w/ engin off. If it spins freely, it’s bad), bad fan (if it has a cheep after market flex fan these blades get weak), missing fan shroud, partially clogged radiator (have flushed), bad water pump (possibly a broken impeller. check last) . If it has A/C it could have a bunch of junk between the condenser and radiator (this happened to me on a Corvette).
