Problem Description and Possible Solution

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.

My coolant expansion tank is leaking a little and my local dealership want to charge me over $300 to replace the tank. I think that is too steep. Can I purchase the part myself and have someone to put it on.

Please advise
