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.

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.
