Product Details

This Continental molded hose is engineered around the original equipment shape and dimensions for upper radiator service. Hose 1 inside diameter measures 1.440 inches, hose 1 length measures 15.990 inches, and the end 2 hose inside diameter is 1.440 inches. Those dimensions matter for maintaining correct coolant transfer and secure connection points in the cooling system. Continental 62803 is a direct-fit radiator coolant hose for 2003-2009 Lexus GX470 upper applications and 2003-2009 Toyota 4Runner upper applications.

Continental’s Molded line focuses on OE-style hose construction and formed routing for vehicles that require a specific bend profile. For shoppers searching for a 2003-2009 Lexus GX470 upper radiator hose or a 2003-2009 Toyota 4Runner upper coolant hose, this molded design helps match the factory layout without guesswork. This part cross-references Dayco 72301 and Gates 22831 for the same application.

Common Issues This Hose Can Address

• Cracked or hardened upper radiator hose material
• Coolant seepage at the hose connection points
• Incorrect hose routing from a previous replacement
• Loss of coolant flow through the upper cooling circuit
• Fitment problems caused by non-molded universal hoses

Installation Notes and Tips

Verify the hose routing against the original upper radiator hose before installation. Confirm the inside diameter and molded shape match the vehicle’s factory layout, especially on 2003-2009 Lexus GX470 and 2003-2009 Toyota 4Runner models. Inspect adjoining clamps, necks, and coolant passages for wear or corrosion before installing the new hose.
