Overflow Radiator Tank

Overflow radiator tanks are components of the engine cooling system in non-aircraft vehicles. They are part of the engine accessories supply group. These tanks are designed to collect and store excess coolant that is expelled from the radiator due to pressure build-up or overheating. The overflow radiator tank helps maintain the proper coolant level in the system by allowing the coolant to expand and contract as needed. It also provides a reservoir for the coolant to return to the radiator once it has cooled down. This helps prevent coolant loss and ensures efficient cooling of the engine.
