  This is a genuine Ford OEM coolant reservoir or expansion tank for the 2021 through 2025 Ford Bronco. Part number MB3Z-8475-H is the cooling system overflow bottle or pressurized reservoir that accommodates coolant expansion and contraction as the system heats and cools through the operating cycle. The reservoir includes the molded tank, integrated low coolant level sensor port where applicable, hose attachment fittings, mounting bosses, and the pressure cap interface.
