Product Details

Dayco’s Curved Radiator Hose line focuses on replacement hoses shaped for specific engine-bay routing needs. Part number 70241 follows that approach with a curved profile, EPDM material, and SAE-rated construction to support proper coolant transfer in applications that call for a 1-inch hose connection. The hose is listed for Nissan Pathfinder, Nissan Pickup, and Nissan D21 models, along with several Chrysler passenger-car and wagon applications from the late 1950s.

Use Dayco 70241 when replacing a worn, cracked, softened, or leaking radiator hose on the listed vehicles. The fitment data includes 1990-1995 Nissan Pathfinder, 1995 Nissan Pickup, 1990-1994 Nissan D21, and 1957-1958 Chrysler 300, Imperial, New Yorker, Town & Country, and Newport.

What This Hose Helps Address

• Coolant leaks from aged or split hose rubber
• Softening, swelling, or collapse in an existing hose
• Improper hose routing caused by a damaged curved hose
• Cooling-system service on vehicles with a 1-inch hose connection
• Replacement of a hose that no longer seals securely at the ends

Installation Notes and Tips

Confirm the hose routing, end diameters, and shape against the removed part before installation. Inspect hose clamps, necks, and nearby cooling-system components for wear or corrosion, and replace any damaged mating surfaces before filling and bleeding the system. Verify that the hose seats fully on both connections and that the routing does not contact moving or hot engine components.

Quality Assurance

Dayco 70241 is manufactured to SAE J20R4 Class D-1 and SAE J1684 Type EC requirements for hose performance. The EPDM construction and application-specific curved design support a direct replacement for the listed Nissan and Chrysler vehicles.
