Product Details

The Dayco Curved Radiator Hose line focuses on formed cooling hoses that match specific routing requirements in the engine bay. Part number 72662 is shaped for the engine to water pump connection and uses EPDM material to handle coolant exposure in a standard cooling system environment. Its curved profile and matched end diameters support a clean replacement for the original hose layout on the listed Ford Five Hundred, Ford Freestyle, and Mercury Montego applications.

This part cross-references Ford 579Z-8A577-AC and Gates 23009 for the same application. Dayco 72662 is also referenced by ACDelco 20444S, CARQUEST 23009, Duralast C72662, Goodyear 62332, and NAPA 9674.

What This Hose Helps Address

• Coolant leaks from a cracked or aged bypass hose
• Softening, swelling, or deterioration of the original EPDM hose
• Improper coolant routing between the engine and water pump
• Loss of cooling system integrity caused by hose wear
• Replacement needs on a curved radiator hose with matched end sizing

Installation Notes and Tips

Verify the hose routing, end diameters, and engine-to-water-pump position before installation. Inspect adjoining fittings, clamps, and nearby cooling components for wear or corrosion so the replacement hose seats correctly and seals properly. Confirm vehicle application by year, make, and model: 2005-2007 Ford Five Hundred, 2005-2007 Ford Freestyle, and 2005-2007 Mercury Montego.

Quality Assurance

Dayco 72662 is manufactured to SAE J20R4 Class D-1 and SAE J1684 Type EC standards, supporting consistent material and performance requirements for cooling system hose applications.
