High Performance Radiator Caps

A radiator cap is a severely important part for your engine. A radiator cap allows the engine’s coolant to expand and contract without allowing air to enter the cooling system. Its important to have a radiator cap that is properly rated for your engines pressure. As the engine’s coolant heats up, it expands, increasing the pressure inside the closed coolant system. The radiator cap controls the expansion and provides a constant pressure on the system. A factory radiator cap is not designed to work efficiently with your high performance engine. Factory caps individual ratings may vary, but are generally anywhere from 13-16 psi. A High Performance Radiator Cap generally ranges anywhere from 19 – 32 psi.

There are many options when deciding which aftermarket radiator cap to go with. Some manufacturers have options that will include a thermostat on the cap so you’re able to monitor your coolant temperature. Other manufactures have caps that feature a safety release. No matter what option you decide to go with, its important to make sure your new cap will be able to handle the high pressure from your modified engine. If you have any questions regarding high performance radiator caps for your 2006 Ford F-150, reach out to one of our experienced representatives and we will help you make a more informative decision.

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 2006 Ford F-150’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 2006 Ford F-150’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 2006 Ford F-150 perform at its peak efficiency, or both, we have you covered. Here, at Sport Compact Warehouse 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.
