What happens to coolant in a blown head gasket?
It keeps the combustion gases in the combustion chamber while keeping the coolant in the water jacket. A blown head gasket will allow coolant to leak into the combustion chamber, or externally, or could allow combustion gases into the cooling passages. If coolant leaks into the combustion chamber it will come out of your tail pipe as white smoke.
What does it mean when antifreeze goes out of an engine?
It could be a blown head gasket, a fractured cylinder head, damaged cylinder bores, or a manifold leak. It could also be a hydraulic lock. If the antifreeze vanishes without any apparent reason, check these components for cracks, damage, or defects. Any of these issues can destroy the engine if it is going for too long.

If the head gasket fails between an oil gallery and a water passage it will allow the engine oil and coolant to mix. This will result in contaminated oil (the white milky sludge or “milk shake” associated with a blown head gasket) and a compromise the cooling system.
