Product Details

This Dayco curved radiator hose is shaped for lower radiator routing and built to handle coolant flow in the Toyota Tacoma cooling circuit. The EPDM material is commonly used in radiator hose construction for its resistance to heat and coolant exposure, while the curved profile helps match the factory hose path. Dayco 72322 is a direct-fit style replacement for Tacoma owners searching for a lower radiator coolant hose, Toyota Tacoma lower hose, or Dayco 72322 radiator hose.

Dayco’s Curved Radiator Hose line focuses on application-specific hose geometry and OE-style fitment for cooling system service. This part cross-references Toyota (e.g., 16572-0C110) for the same application.

What It Helps Address

  • Cracked or split lower radiator hose
  • Coolant leaks at the hose connection points
  • Softening or swelling from age and heat cycling
  • Restricted coolant flow caused by hose deterioration
  • Cooling system service on 2005-2016 Toyota Tacoma models

Installation Notes and Tips

Verify hose routing and end diameters before installation. Inspect the radiator neck, engine connection, and clamps for wear or corrosion before transferring the new hose into place. Confirm the hose follows the original curved path without twisting so the Tacoma cooling system maintains proper clearance and alignment.

Quality Assurance

Dayco 72322 is manufactured to SAE J20R4 Class D-1 and SAE J1684 Type EC standards for radiator hose applications. The part number 72322 is listed for 2005-2016 Toyota Tacoma lower hose service.
