I just bought this 68 302. changed the radiator cap and water pump. It get up to temp and starts to boil and push out the over flow tube until it is completely drained. new thermostat too. Any ideas??? no leaks or coolant in the oil.
I replace water pump first and nothing. At the same time which was great...flushed the crap out the radiator. But, it was the thermostat the guy never changed it like he told me he did. all is good for now lol
Thanks for all the info.
