What It Helps Address

• Cracked or aged upper radiator hose material
• Coolant leaks at the hose body or ends
• Incorrect hose shape after prior replacement
• Cooling system service on vehicles with molded upper hose routing
• Fitment issues caused by using a universal hose instead of a formed hose

Installation Notes and Tips

Verify the hose routing, end diameters, and centerline length before installation. Confirm the application by year, make, model, and upper position for Nissan Armada, Nissan TITAN, INFINITI QX56, or Pathfinder Armada. Inspect adjoining clamps, necks, and cooling system surfaces for wear or corrosion before installing the new hose.
