Description:Coolant overflow reservoirs capture antifreeze as it expands from the radiator, and return it there as it cools. The reservoir plays an important part in the health of your engine¡¯s cooling system, and if yours is cracked or damaged, your engine could overheat. Before that happens, replace it with an OE-equivalent unit from CA Auto Parts. Our coolant reservoirs are molded from the highest quality plastic and are designed as direct drop-in fitments. The reservoirs include caps, and are priced well below the cost of a dealer-supplied unit.
