Installation Notes and Tips

Verify the hose route, end diameters, and centerline length before installation. Inspect the mating necks, clamps, and nearby cooling components for wear or corrosion, and replace any damaged hardware as needed. Confirm the vehicle is fully cooled and the cooling system is properly refilled and bled after service.
