Gates 22698 Molded Coolant Hose Overview

Detailed Description

Common Problems This Hose Can Address

• Cracked or hardened upper radiator hose material
• Coolant leaks at the hose body from age or heat cycling
• Collapsed or misshaped hose routing in the cooling system
• Incorrect fit from a straight hose used in a formed application
• Cooling system service on select Silverado and Sierra HD trucks

Installation Notes and Tips

Verify the hose routing, end diameters, and centerline length before installation. Match the hose to the upper position only, and inspect adjoining clamps, necks, and coolant connections for wear or corrosion before reassembly. Drain coolant as needed and confirm the hose seats fully on both ends after installation.
