Dayco 70469 Radiator Coolant Hose - Upper

Dayco Curved Radiator Hose 70469

Dayco 70469 is a curved radiator coolant hose built for upper cooling-system routing on select Ford applications. Made from EPDM rubber with a black finish, it uses a single I.D. hose design with 1 1/2-inch inside diameter ends for a direct replacement-style fit.

This Dayco Curved Radiator Hose line is engineered for cooling-system service where a formed hose is needed to follow the factory path without kinking. The 70469 part number is a fitment-focused option for Ford E-Series vans and a 1966 Ford LTD upper hose application.

Detailed Description

Dayco 70469 is a curved radiator coolant hose for upper radiator routing on compatible Ford vehicles. The formed shape helps match the factory hose path on 1986-1987 and 1988-1994 Ford E-150 Econoline, E-250 Econoline, E-350 Econoline, and related Club Wagon models, plus the 1966 Ford LTD upper hose application noted in the fitment data. If you are searching for a Ford E-150 Econoline upper radiator hose, Ford E-250 Econoline Club Wagon curved radiator hose, or a replacement radiator coolant hose for a 1966 Ford LTD, this part number is a direct reference point.

The hose is made from EPDM, a common coolant-hose material selected for radiator and heater circuit service. Its 1 1/2-inch end diameters and curved profile support proper routing in applications where a straight hose would not match the original layout. This part cross-references Gates 20355 for the same application.

What It Helps Address

• Cracked or aged upper radiator hose material
• Coolant leaks at the hose body or connection points
• Improper hose routing caused by a misshaped or incorrect hose
• Softening, swelling, or deterioration from heat and coolant exposure
• Replacement needs for Ford E-Series upper radiator hose service

Installation Notes and Tips

Verify hose routing, end diameter, and upper-position fitment before installation. Inspect the radiator neck and engine-side connection points for corrosion, residue, or damage before transferring the new hose into place. Confirm that the hose follows the original curved path without twisting so the cooling system maintains proper clearance and alignment.
