What is a Radiator Water Tank?

The radiator water tank (or coolant expansion tank) is a plastic reservoir mounted in the engine bay, which holds the coolant required by the engine. It allows excess coolant to overflow into it when it expands. You can locate the radiator water tank by following the hose from the radiator.

A cracked or broken tank could allow coolant to leak, which, in turn, damages your engine due to overheating.
