Installation Notes:

• Drain coolant completely before removing the old radiator to avoid spills and scalding.
• Detach shrouds, hoses, and fan wiring, then inspect mounting brackets for any bends or cracks; replace as needed.
• Clean all mating surfaces and verify the radiator mounts align with the frame rails to prevent flexing during use.
• When reassembling, use a fresh coolant with the correct mix ratio and bleed the system to remove trapped air; verify no air pockets remain in the top hose or radiator neck.
• Inspect fins for damage; use a fin comb to straighten lightly bent fins for maximum airflow.
• Check for leaks after initial startup and monitor operating temperatures closely during the first trail or work session.

Why Upgrade?

Running a worn or damaged radiator can lead to overheating, reduced engine performance, and potential head gasket or piston damage under heavy workloads. Replacing with a capable aftermarket radiator restores cooling efficiency, maintains consistent operating temperatures, and helps keep your ATV/UTV reliable in challenging conditions.
