What is a Coolant Expansion Tank?

A coolant expansion tank is a reservoir that stores and protects excess coolant. The overflow of coolant is caused by expansion when the coolant reaches high temperatures. The expansion tank catches the overspill coolant before recirculating it into the engine. It keeps the coolant level consistent in the system. 

If your coolant levels are dropping, there may be a leak in the coolant expansion tank. If this checks out, it's crucial you get a replacement as soon as possible.
