AN intake gasket leak will not cause bubbles in the coolant and an overheat concern. The easiest and quickest way to check for a headgasket failure is to use a combustion gas leak detector. It sniffs the air the [radiator](/topics-radiator-chevy/) and if it finds traces of combustion gas the fluid changes color. Indicating a headgasket leak.
