Dayco 72568 Radiator Coolant Hose - Lower

Dayco 72568 Curved Radiator Hose

Dayco 72568 is a curved radiator coolant hose built for lower cooling-system routing where a dual inside diameter is required. Made from EPDM and finished in black, it is shaped for applications that need a 1 3/4 in. end on one side and a 2 in. end on the other.

Compatible with select Ram 1500, Ram 2500, Ram 3500, Dodge Ram 1500, Dodge Ram 2500, Ford E-350 Super Duty, and Ford E-350 Club Wagon applications, this hose follows the fitment and dimensional requirements listed for the vehicle-specific lower hose position.

Key Features

• EPDM construction for cooling-system hose service
• Dual I.D. hose design with 1 3/4 in. and 2 in. ends
• Curved radiator hose profile for lower hose routing
• Black finish for a clean OE-style appearance
• Built to SAE J20R4 Class D-1 and SAE J1684 Type EC specifications
• Dayco Curved Radiator Hose line for vehicle-specific cooling applications

Product Details

Dayco 72568 is a radiator coolant hose engineered for lower radiator connections where the hose must transition between different inside diameters. The EPDM rubber construction is suited to coolant circulation service, while the curved shape helps match the routing used on the listed Ram and Ford applications. This part cross-references Motorcraft KM4813 and Gates 23076 for the same application.

Use Dayco 72568 when replacing a worn, cracked, swollen, or leaking lower radiator hose on 2011-2018 Ram 2500, 2011-2018 Ram 3500, 2011-2016 Ram 1500, 2009-2010 Dodge Ram 1500, 2010 Dodge Ram 2500, 2004-2010 Ford E-350 Super Duty, or 2004-2005 Ford E-350 Club Wagon.

What This Hose Helps Address

• Coolant leaks at the lower radiator hose connection
• Softening, cracking, or swelling from heat and age
• Improper hose fit caused by incorrect inside diameter sizing
• Cooling-system service on curved lower hose routing
• Replacement of a deteriorated hose on Ram and Ford van/truck applications

Installation Notes

Verify end diameters, routing, and lower-position fitment before installation. Inspect hose clamps, radiator necks, and adjoining coolant pipes for wear or corrosion, and confirm the hose seats fully on both connections. After installation, refill and bleed the cooling system according to the vehicle service procedure and check for leaks at operating temperature.

Quality Assurance

Dayco 72568 is built to published SAE J20R4 Class D-1 and SAE J1684 Type EC requirements for radiator hose service. The Curved Radiator Hose line is intended to meet the dimensional and material needs of the listed vehicle applications.
