Detailed description

Dayco 71353 is a radiator coolant hose for vehicles that use a curved upper hose path and dual inside diameters. The EPDM material is suited to coolant service, while the hose geometry supports the listed Nissan D21 and Pathfinder applications as well as Isuzu Pickup and Rodeo fitments. If you are replacing a worn upper radiator hose on a Nissan D21, Nissan Pathfinder, or Isuzu Pickup, this part number provides the specified hose shape and connection sizes needed for the cooling circuit.

Common replacement issues

• Coolant leaks from a cracked or aged hose.
• Softening, swelling, or collapse in the hose body.
• Incorrect hose routing on curved upper cooling connections.
• Mismatch between hose end diameters and the vehicle fittings.

Installation notes and tips

Verify the listed position and notes before installation, since this hose is cataloged for upper, upper - pipe to engine, and upper - pipe to radiator applications. Confirm the end diameters and routing path against the removed hose before service. Inspect adjoining clamps, pipes, and radiator necks for wear or corrosion before completing the repair.
