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.
Since the head gasket seals the coolant passage both from the atmosphere and the combustion chamber you canât see or get too much of the head gasket on a vehicle. Because much of the gasket canât be seen without disassembling the engine, it can be very difficult to diagnose a head gasket leak.
