What It Helps Address

• Cracked or softened lower radiator hose material
• Coolant leaks at a worn hose connection
• Improper hose routing on curved lower hose applications
• Chafing where the hose passes near nearby components
• Cooling-system service on aging Chevrolet and GMC trucks and SUVs

Installation Notes and Tips

Verify the vehicle year, make, model, and lower hose routing before installation. Confirm both end inside diameters, the curved shape, and radiator fitment against the removed hose or service information. Inspect hose necks, clamps, and adjacent cooling-system parts for wear before refilling the system.
