Dayco Curved Radiator Hose for OE-Style Cooling Service

Dayco 70020 is a curved radiator coolant hose built for specific upper and lower cooling-system routes on select Chevrolet, Ford, Oldsmobile, and Toyota applications. Made from EPDM rubber and finished in black, it follows the original hose path for a direct replacement in service work.

Key Features

  • EPDM construction for coolant-system durability
  • Single I.D. hose with 1 1/2 in. inside diameter at both ends
  • Curved radiator hose profile for routed engine bay fitment
  • Black finish for a clean OE-style appearance
  • Built to SAE J20R4 Class D-1 and SAE J1684 Type EC specifications
  • Compatible with upper and lower radiator hose locations listed below

Product Details

This Dayco Curved Radiator Hose is part of the Dayco Curved Radiator Hose line and is engineered for cooling-system replacement where the hose must follow a formed bend rather than a straight run. The EPDM rubber construction is suited for coolant exposure, while the 1 1/2 inch end diameters support the listed OE-style applications. Dayco 70020 cross-references ACDelco 22001M for the same application.

Compatible With 1992 Toyota Land Cruiser, lower - pipe to engine; 1991 Toyota Land Cruiser, lower - engine to pipe; 1990 Toyota Land Cruiser, lower - pipe to engine; 1974 Ford E-100 Econoline, upper; 1965 Chevrolet Corvette, upper; 1961 Oldsmobile 98, upper; and 1955-1957 Chevrolet Bel Air, upper. Dayco 70020 is a direct-fit radiator coolant hose choice for these vehicle-specific cooling layouts.

Common Cooling Issues This Hose Can Address

  • Cracked or hardened radiator hose rubber
  • Coolant seepage at a formed hose section
  • Collapsed or softened hose walls from age and heat
  • Incorrect hose routing after prior repair work
  • Loss of proper coolant flow through the upper or lower hose path

Installation Notes and Tips

Verify the hose route, end diameters, and position before installation. Match the upper or lower location exactly to the vehicle listing, and inspect the mating pipe and radiator neck for corrosion, scale, or sharp edges that can shorten hose life. Confirm clamp condition and coolant level after service.

Quality Assurance

Dayco 70020 is manufactured to SAE J20R4 Class D-1 and SAE J1684 Type EC requirements for radiator coolant hose applications.
