Acting as a pressure valve for the radiator, a radiator cap is of vital importance to maintain the efficiency of the cooling system. Its main purpose is to keep the engine coolant within the radiator under the certain amount of pressure, thus raising the boiling point of the fluid and helping to avoid overheating. A radiator cap also helps avoid excessive pressure buildup within the system by diverting a small amount of hot coolant into the overflow reservoir and drawing it back once the pressure has reached acceptable levels.
Having a properly functioning radiator cap is a perfect solution to be sure that the engine coolant will stay where it has to be – inside the cooling system instead of flowing like a waterfall into the overflow tank or evaporating in mere seconds. Here at CARiD, we pride ourselves on offering an extensive collection of first-rate replacement radiator caps that are designed with utmost care to provide proper operation of your vehicle’s cooling system. Made to the strictest OE quality standards, they are sure to provide excellent performance.
When it comes to getting the most out your vehicle’s cooling system, there are a lot of things you must consider. When faced with high-load driving conditions, the pressure levels in your radiator go through the roof. Unlike your factory caps that are unable to handle such pressure releasing it through a pressure release valve and causing the fluid to blow out like a geyser, high-pressure radiator caps have higher pressure ratings, which means they allow for a higher pressure inside of the cooling system, thus increasing the boiling point of the engine coolant, reducing the risks of overheating and keeping the fluid flowing within the system.
Whether you want to dress up your engine bay in style or make the cooling system of your vehicle perform at its peak efficiency, or both, we have you covered. Here, at CARiD we do our utmost to provide you with a comprehensive array of premium performance radiator caps that are made with great craftsmanship to deliver unmatched quality. Polished, chrome-plated, anodized, etc. – we have the right product to suit even the most discerning of tastes. The radiator caps we supply are manufactured using only top grade materials to ensure that they will stand the test of time and provide reliable operation even under the toughest conditions. For those who crave for both exceptional touch of style and rock-solid durability we offer radiator caps that are crafted from hand laid carbon fiber.
The radiator caps we offer can help you gain a cooling efficiency boost and give a more stylish look to your engine bay, but some of them can help you do even more. On our virtual shelves you can also find radiator caps with a built-in calibrated thermometer that does a great job of showing the coolant temperature, thus allowing you to see when it’s a safe time to remove the cap. Knowing your coolant temperature, you can change the fluid without having any burn injuries to your hands caused by the hot coolant. Regardless of the radiator cap you will purchase, you are sure to keep the cooling system running efficiently while giving your engine bay the appearance it deserves.
