Dayco 71764 is a curved radiator coolant hose built for cooling-system service on select Ford trucks. Made from EPDM and finished in black, this single I.D. hose is sized with 1 15/16-inch inside diameters at both ends for a direct replacement application.

Compatible with 1995 Ford F-250 lower and 1995 Ford F-350 lower early curved radiator hose applications, this hose is specified to SAE J20R4 Class D-1 and SAE J1684 Type EC standards. The Dayco Curved Radiator Hose line focuses on formed hose routing for vehicles that need a precise bend to follow the factory cooling path.

Product Details

This Dayco radiator coolant hose is shaped for lower radiator routing on the 1995 Ford F-250 and 1995 Ford F-350 early applications. The curved profile helps maintain the factory hose path, while the EPDM rubber construction is suited for coolant circulation and temperature exposure in the engine bay. If you are replacing a worn lower hose on a Ford F-250 or Ford F-350, Dayco 71764 provides the correct formed-hose dimensions for the listed fitments.

This part cross-references Ford OE numbers F4TZ-8286-D and F5TA-8B273-ME for the same application.

Common Uses

  • Replacing a cracked or aged lower radiator hose
  • Restoring coolant flow on a 1995 Ford F-250 lower hose application
  • Restoring coolant flow on a 1995 Ford F-350 lower hose application
  • Addressing coolant seepage at the hose ends
  • Correcting hose routing on an early curved radiator hose setup

Installation Notes

Verify end diameters, routing, and position before installation. Inspect hose necks, clamps, and adjoining cooling-system components for wear or corrosion before fitting the new hose. Confirm the hose follows the original curved path without twist or kinking, and refill and bleed the cooling system according to the vehicle service procedure.

Quality Assurance

Dayco manufactures this hose to published SAE specifications for radiator hose service, supporting consistent material and dimensional requirements for the listed Ford truck applications.
