Question

Quizplus · Accepted Answer

Air blowing out through the radiator indicates a blown head gasket, which allows compressed air from the cylinder to escape into the engine's cooling system and be forced out through the radiator. A cracked intake manifold or a bad water pump would not cause air to blow out through the radiator, and a crack at the bottom of a cylinder would not necessarily be related to the cooling system.
