1994 Buick Skylark Q&A

1994 Buick Skylark Question: headgasket

could overfilling the antifreeze/coolant after a recent radiator replacement cause head gasket to leak? does steel seal work on my gasket? -
Answer 1
Over filling would not hurt your head gasket. Most likely, when the radiator wore out, it allowed the engine to over badly over heat. When I check out an engine that has run out of coolant, I do a Block Check to make sure that the head gasket is still intact. -
