Product Details

Dayco Curved Radiator Hose 72676 is a lower radiator coolant hose engineered for vehicles that use a dual inside diameter connection. The EPDM rubber construction is suited for coolant transfer, while the curved shape helps match the original hose routing in the engine bay. This hose is listed for 2005-2010 Cadillac STS, lower, w/o Tow Pkg.; Curved Radiator Hose, and 2004-2009 Cadillac SRX, lower, w/o Tow Pkg.; Curved Radiator Hose. This part cross-references ACDelco 26511X and Gates 23034 for the same application.

Common Cooling System Issues

  • Cracked or hardened lower radiator hose
  • Coolant seepage at the hose connection points
  • Collapsed or weakened hose under operating temperature
  • Incorrect hose shape or diameter for factory routing
  • Cooling-system service on Cadillac STS and Cadillac SRX models

Installation Notes

Verify the vehicle is a 2004-2009 Cadillac SRX or 2005-2010 Cadillac STS with lower hose routing and without the tow package before installation. Match the hose ends to the dual I.D. connection sizes and confirm the routing follows the original curved path. Inspect clamps, necks, and adjacent cooling components for wear before reassembly.

Quality Assurance

Dayco manufactures this hose to SAE J20R4 Class D-1 and SAE J1684 Type EC requirements, supporting consistent material and dimensional standards for cooling-system service.
