Installation Notes and Tips

Verify hose routing, end diameters, and centerline length before installation. Match the molded shape to the original hose path so the hose clears nearby components and maintains proper alignment. Inspect adjoining clamps, fittings, and connection points for wear or corrosion before installing the new hose. Confirm the application against the vehicle’s cooling system layout for the exact year and model.
