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.
An external leak is visible outside the engine, an internal leak means that coolant can seep into oil passages or erode the compression sealing ring in the head gasket allowing coolant to enter the cylinder or compression to enter the cooling system. This is what we call a âblownâ head gasket. While an improperly maintained cooling system can cause head gasket failure. There are some vehicles that are simply prone to head gasket failure, this is due to the composition of the head gasket material and overall engine design.
