An engine coolant leak may develop from the expansion tank resulting in engine overheating. When a cooling system component fails the entire cooling system should be inspected. It is not uncommon to find additional component have failed or are leaking.

Overheating can cause severe engine damage. If the engine begins to overheat it is recommended to stop at the first available location and have your vehicle towed to a repair shop.

    Thermostat caused check engine light. Changed water at same time, impeller had small piece missing and small cracks. Expansion tank developed a small crack 500 miles later. Should have done it at the same time.
