Detailed Description

Dayco 72284 is a curved radiator coolant hose engineered for upper hose applications where the hose must follow a formed path between the engine and radiator. The EPDM material is commonly used in cooling-system hoses for its resistance to heat and coolant exposure, while the curved profile helps maintain proper routing in tight engine bays. This part number 72284 is listed for 2005-2010 Chrysler 300, 2009-2010 Dodge Challenger, 2006-2010 Dodge Charger, and 2005-2008 Dodge Magnum upper radiator hose positions.

This part cross-references Gates 22942 for the same application.

What It Helps Address

• Cracked or hardened upper radiator hose material
• Coolant leaks at the hose body or connection points
• Collapsed or softened hose sections from age and heat
• Improper hose routing caused by a damaged formed hose
• Cooling-system service on Chrysler 300, Dodge Charger, Dodge Challenger, or Dodge Magnum models

Installation Notes and Tips

Verify the hose shape, end diameters, and upper-position routing before installation. Confirm the vehicle year and model match the listed fitment for Dayco 72284, and inspect the mating necks, clamps, and coolant condition during replacement. Proper seating at both 1 7/16-inch ends is important for sealing and long-term service.
