Dayco 70472 Radiator Coolant Hose - Lower

Dayco Curved Radiator Hose 70472

Dayco 70472 is a curved radiator coolant hose built for lower cooling-system routing where a dual inside diameter is required. It uses EPDM construction and follows SAE J20R4 Class D-1 and SAE J1684 Type EC specifications for service in demanding coolant applications.

Compatible With 1965-1967 Ford LTD, lower, and 1967 Mercury Villager, lower. This Dayco Curved Radiator Hose line is engineered for vehicle-specific cooling layouts, with formed routing that helps match the original hose path in classic Ford and Mercury applications.

Key Features

• EPDM rubber construction for coolant-system service
• Dual I.D. hose design with 1 3/4 in. and 2 1/8 in. ends
• Curved radiator hose profile for lower hose routing
• Black finish for a clean OE-style appearance
• Built to SAE J20R4 Class D-1 and SAE J1684 Type EC standards
• Dayco part number 70472 for catalog and cross-reference lookup

Product Details

Dayco 70472 is a radiator coolant hose for lower-position applications that require a curved shape and different end diameters. The EPDM material is selected for coolant exposure, while the formed design supports proper routing in the engine bay. This hose is listed for 1965-1967 Ford LTD lower radiator hose service and 1967 Mercury Villager lower radiator hose service, making it a direct-fit replacement for those applications. The part number 70472 is also useful when cross-checking cooling-system service parts for classic Ford and Mercury vehicles.

This part cross-references Ford (e.g., C5AE-8286-G, C5AZ-8286-A) for the same application.

Common Replacement Reasons

• Cracked or hardened lower radiator hose
• Coolant seepage at the hose ends
• Collapsed hose under operating temperature
• Incorrect hose shape or end diameter during replacement
• Cooling-system service on a 1965-1967 Ford LTD or 1967 Mercury Villager

Installation Notes and Tips

Verify the lower hose routing, end diameters, and connection points before installation. Inspect the radiator neck, water pump outlet, and clamps for wear or corrosion, and replace any damaged sealing surfaces before fitting the hose. Confirm that the hose follows the original curved path without twisting so coolant flow is not restricted.

Quality Assurance

Dayco cooling hoses are built to meet published SAE specifications for radiator hose service. Part number 70472 is manufactured as an EPDM curved radiator hose for the listed Ford LTD and Mercury Villager applications.
