Detailed Description

What It Helps Fix

• Cracked or split upper radiator hose
• Coolant leaks at a worn hose body
• Softening or swelling from age and heat
• Improper hose routing after a failed replacement
• Restricted coolant flow caused by hose deterioration

Installation Notes and Tips

Verify end diameters and centerline length against the original hose before installation. Confirm the hose route matches the factory upper position on the vehicle, and inspect adjoining clamps, necks, and coolant connections for wear or corrosion before reassembly. After installation, refill and bleed the cooling system according to the vehicle service procedure.
