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.
The biggest cause of a blown head gasket is overheating. Usually, the head gasket armor around the cylinders can become crushed, and if this happens, the seal is lost and your engine will lose compression, leak coolant, and the gasket will erode.
