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.
A. Bubbles. A blown head gasket and/or cracked head can cause bubbles of air to be visible in the radiator or expansion tank. To check for this, remove the radiator cap, warm up the engine and on a warm engine some head gasket problems will present with bubbles being visible in the radiator or expansion tank.: Paul, if the engine has been overheated it is possible that you have blown a head gasket, cracked or warped a head. If a cylinder head gets too hot it can swell to the point where it crushes the head gasket. This will usually occur at the thinness point of the head gasket which is between the engine cylinders.
