Product Details
This Dayco curved radiator hose is made for cooling-system service where a formed upper hose is required. The EPDM material is commonly used in radiator hose applications because it is suited to coolant exposure and under-hood temperatures. The dual I.D. configuration helps match the differing inlet and outlet sizes found on the vehicle side and radiator side of the system. Dayco 72334 is a direct-fit style replacement for 2003-2006 Dodge Sprinter 2500 and 2003-2006 Dodge Sprinter 3500 upper radiator hose applications. This part cross-references ACDelco 22499M and Gates 22878 for the same application.

Installation Notes
Verify the hose routing, end diameters, and upper-position fitment before installation. Inspect the radiator necks and engine-side connections for corrosion, debris, or sharp edges that can affect sealing. Replace worn clamps as needed and confirm the hose is fully seated before refilling and bleeding the cooling system.
