Product Details

Dayco’s Curved Radiator Hose line focuses on replacement hoses shaped for specific cooling-system paths, helping maintain proper coolant flow where a formed hose is required. Part number 72373 uses EPDM material for durability in engine-bay heat and coolant exposure, with matching end diameters and outside dimensions that support a precise upper-hose replacement. For buyers searching for a Chrysler Aspen upper radiator hose or Dodge Durango upper coolant hose, Dayco 72373 provides a direct-fit option for the listed applications.

This part cross-references Chrysler (e.g., 52028988, 52028988AB) for the same application.

What It Helps Address

• Cracked or deteriorated upper radiator hose
• Coolant seepage at the hose body or connection points
• Restricted coolant flow caused by a damaged hose
• Incorrect hose shape on a replacement cooling repair
• Heat-related hose hardening in the engine bay

Installation Notes and Tips

Verify the hose routing, end diameters, and upper-position fitment before installation. Inspect the mating necks, clamps, and nearby cooling components for wear or corrosion, and replace any damaged parts before refilling the system. After installation, refill with the correct coolant and check for leaks once the engine reaches operating temperature.

Quality Assurance

Dayco 72373 is manufactured to meet SAE J20R4 Class D-1 and SAE J1684 Type EC requirements, supporting consistent material and dimensional standards for cooling-system replacement.
