Installation Notes and Tips

Verify hose routing, end diameters, and centerline length against the removed part before installation. Inspect hose clamps, radiator necks, and engine fittings for wear or corrosion, and replace damaged sealing surfaces before filling the cooling system. Confirm the hose is positioned without twists so the molded shape matches the factory path on the Chevrolet Silverado 1500, GMC Sierra 1500, or Cadillac Escalade application.
