Product Details
QuadBoss is known for making reliable parts for ATVs and UTVs, and this radiator cap is no different. It’s a direct replacement for your original cap, meaning it’s built to the same specs and will fit right in. If your old cap is leaking or not holding pressure like it used to, this is a straightforward fix to get your cooling system working properly again.
This cap is rated for 13 psi, which is the standard pressure your cooling system needs to operate efficiently. Keeping the correct pressure in your system helps raise the boiling point of the coolant, preventing overheating on those long rides or tough jobs. It's a well-built part that’s designed to keep your engine running cool.
This cap fits a wide range of Can-Am vehicles, including models like the Commander 1000 XT, Defender HD10, and Outlander 850. It’s a simple, bolt-on part that doesn't require any special tools or modifications to install. Just swap it out with your old one, and you're good to go.
