Dayco Curved Radiator Hose 72111

Dayco 72111 is a curved radiator coolant hose built for specific upper and lower cooling-system routes on select Pontiac, Nissan, and INFINITI applications. It uses EPDM construction with a black finish and a protective sleeve to help manage underhood exposure in demanding cooling circuits.

Key Features

  • EPDM rubber construction for radiator coolant service
  • Black curved hose profile for routed cooling-system connections
  • 1 5/16 in. inside diameter at both ends
  • Protective sleeve included for added abrasion resistance
  • Meets SAE J20R4 Class D-1 and SAE J1684 Type EC specifications
  • Single I.D. hose design for direct coolant transfer

Product Details

This Dayco curved radiator hose is engineered for cooling-system replacement where the hose must follow a formed path between the engine pipe and radiator or the upper radiator connection. The EPDM material is selected for coolant-hose service, while the protective sleeve adds an extra layer where routing passes near surrounding components. Dayco 72111 is a direct-fit style radiator coolant hose for 2008-2009 Pontiac G8 upper applications, 2001-2004 Nissan Pathfinder lower - pipe to radiator applications, and 2001-2003 INFINITI QX4 lower - pipe to radiator applications. This part cross-references ACDelco 24412L and Gates 22532 for the same application.

What It Helps Address

  • Coolant leaks from a cracked or aged radiator hose
  • Softening, swelling, or collapse in an original hose
  • Improper hose routing on a curved cooling-system path
  • Loss of coolant flow between the pipe and radiator connection
  • Heat and abrasion wear in a routed underhood hose location

Installation Notes and Tips

Verify the hose end inside diameter, routing shape, and position before installation. Confirm whether your vehicle uses the upper or lower - pipe to radiator location listed for the application. Inspect adjoining clamps, pipe ends, and radiator necks for corrosion or damage before installing the new hose. For fitment reference, this hose fits 2008-2009 Pontiac G8, upper; 2001-2004 Nissan Pathfinder, lower - pipe to radiator; and 2001-2003 INFINITI QX4, lower - pipe to radiator.

Quality Assurance

Dayco manufactures this hose to SAE J20R4 Class D-1 and SAE J1684 Type EC specifications for radiator coolant hose service. The EPDM construction and protective sleeve support consistent performance in the cooling system.
