Detailed Description

Dayco 72947 is a formed upper radiator hose engineered for 2011-2014 Ford Mustang cooling system service. Its curved profile helps maintain the intended hose path between connection points, while the EPDM rubber construction is suited for coolant exposure and underhood temperature cycling. The single I.D. hose design uses matching 1 1/2-inch end diameters for a straightforward replacement on the specified Mustang upper hose application. Dayco 72947 is a practical choice when replacing a worn, cracked, or softened upper radiator hose on a Ford Mustang.

Common Uses

• Replacing a cracked or split upper radiator hose
• Restoring coolant flow in a Ford Mustang cooling system
• Addressing hose swelling, soft spots, or coolant seepage
• Correcting a formed hose route that no longer holds shape
• Servicing 2011-2014 Ford Mustang upper radiator hose applications

Installation Notes and Tips

Verify hose routing and end diameters before installation. Inspect the radiator neck, engine connection points, and clamps for wear or corrosion, and replace any damaged sealing surfaces before installing the new hose. Confirm the hose is seated fully and routed without twist or contact with hot or moving components. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Quality Assurance

Dayco manufactures cooling-system hoses to meet published SAE specifications, including SAE J20R4 Class D-1 and SAE J1684 Type EC for this part. The protective sleeve adds an extra layer of abrasion resistance in the specified routing area.
