Radiator Caps

UTV and ATV Radiator Caps are an essential part of the cooling system of your all-terrain vehicle. They are responsible for maintaining consistent pressure in the radiator, which helps to regulate the temperature of your ATV's engine. Without a properly functioning radiator cap and a radiator full of OEM or aftermarket coolant, your engine could overheat, leading to costly repairs or even engine failure. High-pressure radiator cap fitments come in a range of styles and sizes, and they are typically made from aluminium or plastic. The most common type is the screw-on cap, which has a threaded piece that screws into the radiator.

Some Honda, Yamaha, Polaris, Suzuki, Kawasaki, or Can-Am models will use a cooling fan and a higher pressure gauge to measure the temperature and pressure of the dirt bike or quad bike to mitigate boiling point temperatures. Kustom Hardware and Whites radiator cap & temperature gauges are on the wishlist for riders around the country with bar radiator cap pressure readings and powersports heat gauges to give you extra peace of mind when out adventuring with your mates! Make sure to check out the list of spare parts for your Polaris RZR or Sportsman and grab a spare air filter, radiator hose kit, or similar motorcycle part.
