Blockage In the Cooling System

If there is a blockage in the cooling system, it can cause the engine to overheat. The jam will prevent the coolant from flowing to and from the engine.

Blown Head Gasket

The head gasket is a seal that sits between the engine block and the cylinder head. It helps to keep the coolant and oil in their respective places.
