Made from EPDM and finished in black, it is shaped for direct replacement use on select Chevrolet Equinox and GMC Terrain models, along with several Chrysler, Dodge, and Plymouth applications.

Key Features

• EPDM construction for coolant-hose service
• Dual I.D. hose design with 1 5/16 in. end 1 and 1 1/2 in. end 2
• Black finish for a clean OE-style appearance
• Curved upper radiator hose layout for specific engine bay routing

• Dayco Curved Radiator Hose line for application-specific cooling system replacement

Detailed Description

Dayco 72542 is a radiator coolant hose engineered for upper hose locations where the hose path must follow a curved route and transition between different diameters. The EPDM rubber construction is suited for coolant circulation, while the dual I.D. design helps match the connection sizes required by the vehicle application. This hose is listed for 2010-2017 Chevrolet Equinox upper radiator hose service and 2010-2017 GMC Terrain upper radiator hose service, as well as 1993-1995 Chrysler Town & Country, Dodge Caravan, Dodge Grand Caravan, Plymouth Grand Voyager, and Plymouth Voyager upper radiator hose applications. This part cross-references Gates 23587 for the same application. Dayco 72542 is a practical replacement choice when servicing a curved upper radiator hose on Chevrolet Equinox or GMC Terrain cooling systems.

What It Helps Address

• Coolant leaks from a cracked or aged upper radiator hose
• Softening, swelling, or collapse in an EPDM hose
• Improper hose fitment caused by mismatched end diameters
• Cooling-system service on a curved hose routing
• Replacement of a worn hose on Chevrolet Equinox and GMC Terrain applications

Installation Notes and Tips

Verify the hose routing, end diameters, and vehicle application before installation. Inspect adjoining fittings, clamps, and the radiator neck for wear or corrosion before transferring the new hose into place. Confirm that the hose follows the original curved path without twist or tension, and refill and bleed the cooling system according to the vehicle service procedure after installation.

Quality Assurance

This hose is manufactured to SAE J20R4 Class D-1 and SAE J1684 Type EC standards, supporting specification-based cooling-system replacement for the listed applications.
