Installation Notes and Tips

Verify the hose path, end diameters, and formed shape before installation. Match the 2-inch inside diameter at both ends to the vehicle’s radiator and engine connections, and inspect adjoining clamps and necks for wear or corrosion. Confirm clearance around nearby components so the curved hose seats without twisting or kinking.
