Dayco 71283 Radiator Coolant Hose - Upper

Overview

Dayco 71283 is a curved radiator coolant hose built for upper cooling-system routing on select Ford trucks and SUVs. It uses EPDM construction and a dual I.D. design to match the hose geometry required for the application.

Compatible With Ford Bronco, Ford F-150, Ford F-250, and Ford F-350 applications listed below. This Dayco 71283 hose is a fitment-based replacement for upper radiator hose service where the original hose follows a curved path.

Key Features

• EPDM rubber construction for cooling-system use.
• Dual I.D. hose design with 1 1/2 in. and 1 3/4 in. inside diameters.
• Curved hose profile for routed radiator connections.
• Built to SAE J20R4 Class D-1 and SAE J1684 Type EC specifications.
• Black finish for a clean engine-bay appearance.

Detailed Description

Dayco 71283 is a radiator coolant hose engineered for upper hose applications where the original part uses a curved shape and dual inside diameters. The EPDM material is selected for coolant exposure, while the SAE specification references indicate a hose built to recognized cooling-system standards. This part number is commonly searched as a Dayco 71283 radiator hose for Ford Bronco and Ford F-Series fitment.

For buyers comparing replacement options, this hose cross-references Motorcraft KM1517 and KM1605 for the same application. Dayco’s curved radiator hose line focuses on application-specific hose geometry, making it easier to match the original routing and connection sizes on the vehicle.

What It Helps Solve

• Cracked or aged upper radiator hose material.
• Coolant leaks at the hose connection points.
• Incorrect hose shape or routing after replacement.
• Mismatch between hose end diameters and the original cooling system.
• Service replacement for a worn Ford upper radiator hose.

Installation Notes

Verify the hose routing, end diameters, and application notes before installation. This part fits 1985-1987 Ford Bronco, upper; 1985-1987 Ford F-150, upper; 1985-1987 Ford F-250, upper; 1985-1987 Ford F-350, upper; 1985 Ford F-150, upper; and 1985 Ford F-250, upper. Confirm the original hose shape and connection sizes match Dayco 71283 before service.
