Detailed Description

The Dayco Curved Radiator Hose 71724 is a radiator coolant hose for upper hose routing in select 1994-1995 Chevrolet C1500, C2500, K1500, K2500 and GMC C1500, C2500, K1500, K2500 trucks. Its EPDM material is suited for coolant exposure, while the curved shape helps follow the factory hose path and maintain proper routing in the engine bay.

This part number, 71724, also cross-references ACDelco 26553X for the same application.

What It Helps Address

• Upper radiator hose leaks caused by aging rubber
• Cracking, hardening, or swelling in the coolant hose
• Improper hose routing on replacement cooling repairs
• Coolant loss from a worn or damaged radiator hose
• Fitment issues when replacing the original curved upper hose

Installation Notes and Tips

Verify the hose routing and end diameters before installation. Inspect the radiator neck, engine connection points, and clamps for wear or corrosion before installing Dayco 71724. Confirm the application is the upper radiator hose position on the listed Chevrolet and GMC trucks, and compare the removed hose to the new part to ensure the curved profile matches the factory layout.
