The Coolant Reservoir that is installed on the Ford Expedition car models is a part of the cooling system of the car, which solves the tasks of preventing a loss of coolant into the roadway and the complete absence of air inside the system. It is used to exclude presence of air that causes rust and corrosion of the cooling system parts and also keeps dangers of leakage of anti-freeze fluid in check. There are two main types of Coolant Reservoirs used in Expedition vehicles: over flow type tank systems and expansion tank systems and the two are fundamentally different concepts despite the fact that they are used in controlling coolant levels and pressure. It is advised that reservoirs be routinely inspected for defects in the body, leaking, and corrosion due to age and thermal expansion/contraction, and coolant fouling that may obscure accurate determination of coolant levels.
