Coolant Reservoir

A coolant tank acts as a regulating component to the excess coolant that’s produced from the heat in your engine. As the warmth rises, coolant expands and overflows into the coolant reservoir and is then sucked back into the radiator as your car cools down after shut-off. Your vehicle relies on your coolant tank to readily accept the excess coolant with each cycle, and a crack or leak means constant replenishing and the possibility of overheating your engine. AutoZone is here to help you keep your cool with a selection of coolant tanks with trusted name brands to ensure lasting performance.
