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 vehicle , reach out to one of our experienced representatives and we will help you make a more informative decision.
