RV radiator overflow / coolant tank, 100% aluminum. This tank is reliable, durable, and corrosion resistant.

The overflow tank's primary function is to assist in the coolant recovery system. Heat expands, coolant is released, and the tank retains the lost coolant. As the engine cools, these coolants are transferred back into the vehicles radiator. It is vital to occasionally check the water levels in the radiator coolant overflow tank for optimal performance.

For REV Group class A motorhomes / RVs such as American Coach, Holiday Rambler, Fleetwood and Monaco Coach. RV Elite part number 08566339. P/n RS-7885.
