Dodge Avenger vehicles' Coolant Reservoir is an essential component in controlling the level and temperature of the used coolant fluid as well as not allowing the entry of air into the system. As a result, problems with rust and corrosion in cooling components with dangerous leakage of antifreeze are prevented. The Dodge Avenger utilizes two primary types of Coolant Reservoirs: two broad categories of tanks which are the overflow tank systems and expansion tank systems. In overflow systems,the cap is installed on the radiator through which coolant is directed to another container provided whenever the pressure is beyond the cap ranking. On the other hand, the expansion tank system comes with the pressure cap on the tank so as to managing the pressurized system so as to allow the coolant to expand and contract. Another part of the Dodge Avenger that needs special attention is the Coolant Reservoir of the vehicle which should be thoroughly inspected for any signs of crack or leakage to enhance the effectiveness of the vehicle and prolong the life span of the car.
