    A radiator cap is considered to be an important component of the engine cooling system that is essential for ensuring that proper amount of cooling system pressure is maintained at all times. Performance radiator caps are not only a great way to add a classy appearance to your vehicle’s engine bay, but they also play a substantial role in improving the efficiency of the cooling system providing even more protection to your valuable investment, no matter whether it’s a high performance race car or a daily driver.

    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.
