You don't want dirt and debris from outside your car or the rest of your engine bay to wind up in your coolant and radiator. Regal radiator caps form a tight seal to protect your radiant, but the cap is easily removed to check on or add coolant. The tight seal also has built-in pressure valves to prevent your radiator – and therefore, your car – from overheating. AutoZone offers Same Day Store Pickup for your convenience and our helpful staff gives trustworthy advice on all of your car repair needs.
