Overheating: Allowing your coolant level to run low can cause damage to your head gasket. When coolant isnât available to pull engine heat from your block and heads, the extra heat can cause expansion on your head gasket, which often results in a blown head gasket.
Engine overheating is the number one cause of head gasket failures, according to Mobil Oil. The cylinder head and engine block expands beyond acceptable limits while overheating, which leads to head gasket pinching. Improperly torqued head bolts and abnormal air fuel mixture combustion are common reasons as well.
