Installation Notes

Verify hose routing, end diameters, and centerline length against the original part before installation. Inspect clamps, necks, and adjoining coolant components for wear or corrosion, and replace any damaged sealing surfaces before filling the system. Confirm the hose position matches the vehicle application, such as upper or lower radiator routing, before final assembly.
