Keep your Polaris RZR performing at its best with the Polaris RZR Pro XP / Pro R Radiator Cap by Quad Logic. This premium 13 psi radiator cap is engineered to maintain the optimal pressure within your cooling system, ensuring consistent engine temperatures and preventing overheating during demanding off-road conditions. Designed as a direct replacement for OEM part numbers #1240508 and #1240044, it offers a precise fit and dependable performance that matches the original Polaris specifications.
A properly functioning radiator cap is one of the simplest yet most essential components of your RZR’s cooling system. When pressure levels drop or the seal weakens, coolant can escape, leading to overheating, engine inefficiency, and potential long-term damage. The Quad Logic radiator cap helps maintain the correct system pressure so that coolant flows efficiently through the radiator and engine, preventing boil-over and maintaining stable temperatures even under heavy loads or high speeds.
Constructed from durable, high-quality materials, this radiator cap is built to handle the extreme conditions of off-road riding. Whether you’re tackling sand dunes, rocky trails, or deep mud, it delivers a secure seal that withstands vibration, heat, and debris. Quad Logic’s precision manufacturing ensures consistent performance, giving you peace of mind that your Polaris RZR Pro XP or Pro R will stay cool and protected wherever you ride.
Installation is quick and simple—no special tools or modifications are required. Just remove your old or damaged radiator cap and replace it with this direct-fit option. Because it meets OEM dimensions and pressure ratings, it installs seamlessly and functions exactly as the original part intended. Regularly replacing worn or failing radiator caps can help extend the lifespan of your engine, reduce maintenance costs, and keep your RZR ready for every adventure.
Invest in the Polaris RZR Pro XP / Pro R Radiator Cap by Quad Logic for reliable cooling performance and long-lasting protection. This small but critical part plays a major role in safeguarding your engine’s health, improving efficiency, and ensuring your RZR is always prepared for the toughest terrains and longest rides.
