This direct-fit cooling module is engineered to drop into your machine with no fabrication, delivering noticeably cooler engine temps under heavy trail work or long tow sessions. Built with a full aluminum core and TIG-welded end tanks, it resists corrosion and stands up to rugged use, providing dependable cooling performance when you need it most. Replaces OEM 1240664.

This radiator combines rugged materials and precise manufacturing to solve common wear-and-tear issues on rugged Terrain—leaking end tanks, warped frames, and heat soak after extended runs. The high-density core and 3003 aluminum construction maximize heat transfer while maintaining a slim, impact-resistant profile for trail or farm duty. With a robust TIG-welded tank construction, this aftermarket solution delivers reliable cooling under load, helping you maintain performance and uptime without the OEM fragility concerns. It’s a dependable upgrade for users who push their Rangers hard on dirt roads, mud, and worksite lanes.

• Mounting: Reinstall with included or OEM-compatible hardware, ensuring the radiator is seated squarely and the fan aligns with the shroud.
• Bleeding & test: Refill coolant, bleed air from the system, and run the engine with the fan-assisted cooling to verify no leaks and normal operating temperature.

Why Upgrade?

Running a worn or damaged radiator dramatically increases the risk of overheating, coolant loss, and engine damage in demanding trail or work conditions. This aftermarket replacement restores cooling efficiency, reduces the likelihood of heat soak, and keeps the Polaris Ranger performing reliably in demanding environments.
