Product Details

Dayco 72959 is part of the Curved Radiator Hose line, a product line focused on formed coolant hoses that match the routing and connection points used in vehicle cooling systems. For the Acura MDX, this upper hose configuration supports the factory-style path between cooling-system components while maintaining the correct hose diameter and bend profile. If you are replacing a worn Acura MDX upper radiator hose, Dayco 72959 provides the specified shape and sizing for the listed vehicles.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems This Hose Can Address

Cracked or hardened upper radiator hose material
Coolant seepage at the hose connection points
Loss of proper hose shape from age or heat cycling
Incorrect fitment from a non-matching replacement hose
Cooling-system service needs on the upper hose route

Installation Notes

Verify the hose routing, end diameters, and upper-position fitment before installation. Inspect the mating necks, clamps, and surrounding cooling-system components for wear or corrosion, and replace any damaged parts as needed. Confirm the hose seats fully on both ends and follows the original curved path without kinks or twist.

Quality Assurance

Dayco 72959 is manufactured to meet SAE J20R4 Class D-1 and SAE J1684 Type EC specifications, supporting consistent material and dimensional requirements for radiator hose service.
