Lexus RX350 RX450H & Toyota Sienna Coolant Reservoir Tank 2010-2020 - Replacement Coolant Overflow Tank for Lexus RX350 (2010-2015), RX450H (2010-2015), Toyota Sienna (2011-2020) - Perfect for Engine Cooling System Maintenance & Repair

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.
