Product Details

Dayco’s Curved Radiator Hose line focuses on formed coolant hoses that follow the factory routing needed in modern engine bays. This Dayco 73136 hose is shaped for the lower radiator connection and uses matching end diameters to support a secure coolant path on 2011-2014 Ford Mustang models. The hose measures 15 inches in trunk height and has an outside diameter of 1 27/32 inches at both ends.

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

Common Cooling System Issues

  • Lower radiator hose cracking or splitting
  • Coolant leaks at the hose connection points
  • Softening or swelling from heat and age
  • Restricted coolant flow from a deteriorated hose
  • Incorrect hose shape or fit at the lower radiator route

Installation Notes

Verify the hose routing, end diameters, and lower-position fitment before installation. Inspect the radiator necks and adjoining coolant pipes for wear, corrosion, or residue before transferring the new hose. Use the vehicle’s specified clamps and refill the cooling system according to factory service procedures after installation.

Quality Assurance

Dayco manufactures this hose to SAE J20R4 Class D-1 and SAE J1684 Type EC specifications for radiator coolant service. Part number 73136 is built for the listed Ford Mustang applications and the dimensional requirements of the lower cooling hose location.
