Dayco Curved Radiator Hose 70440
Dayco 70440 is a curved radiator coolant hose built from EPDM rubber for dependable coolant routing in classic truck and car applications. With 1 1/2-inch inside diameters on both ends and a black finish, this single I.D. hose is shaped for upper and lower cooling-system runs where a formed hose is required.
The Dayco Curved Radiator Hose line focuses on OE-style hose geometry and material selection for direct replacement service. Part number 70440 is a fitment-based solution for vehicles such as Jeep CJ7, Toyota Land Cruiser, Mazda B2000, and Dodge truck and car applications where the original hose follows a curved path.
- EPDM construction for cooling-system use
- 1 1/2-inch inside diameter at both ends
- Curved radiator coolant hose profile
- Single I.D. hose design
- Black finish for a factory-style appearance
- Built to SAE J20R4 Class D-1 and SAE J1684 Type EC specifications
- Fits upper, lower, pipe-to-radiator, and water-pump-to-pipe positions depending on application
Fitment and application details
This hose is listed for 1984-1986 Jeep CJ7, upper; 1984-1985 Jeep Scrambler, upper; 1984-1983 Mazda B2000, lower; 1980-1979 Toyota Land Cruiser, upper; and 1975-1978 Dodge B100, upper. It also covers additional classic Dodge, Ford, GMC, Pontiac, and Jeep applications, including 1970 Ford Mustang, upper; 1966-1968 Ford Bronco, upper - engine to tank; and 1967 Jeep CJ5, upper.
Use this hose when replacing a curved radiator hose on a Jeep CJ7, Toyota Land Cruiser, or Mazda B2000 and the original routing requires the same formed shape. This part cross-references Gates 21794 and NAPA 8484 for the same application.
What this hose helps address
- Coolant leaks from cracked, hardened, or split radiator hoses
- Improper hose routing on curved upper or lower cooling-system runs
- Softening or swelling from age and heat exposure
- Loss of coolant flow caused by hose collapse or deformation
- Replacement needs for original-style hoses on classic Jeep, Toyota, Mazda, and Dodge vehicles
Installation notes and quality assurance
Verify end diameters, hose routing, and position before installation. Match the vehicle’s upper, lower, or pipe-to-radiator configuration exactly, since this part is listed across multiple classic applications with different routing notes. Inspect clamps, necks, and adjoining cooling components during service to confirm a proper seal.
Dayco identifies this hose to SAE J20R4 Class D-1 and SAE J1684 Type EC specifications, supporting a standards-based replacement choice for cooling-system maintenance.
