What can I do about my Chevrolet 4.3 v6 engine overheating?

1 Answer

Answer :

answer:Overheating problems are usually fairly easy to diagnose and I would think if your dad is the owner of a 100 year old truck, he knows how to spin a wrench. I would assume he either didnt properly purge the air out of the radiator and hoses (meaning there are probably large bubbles and the cylinder walls aren’t getting properly cooled) or he’s got a blown headgasket. You can usually ID that if there is fluid leaking from the heads or the rad fluid is spotty or milky.
