Product Details

Dayco 72220 is part of the Curved Radiator Hose line, a product line focused on molded cooling hoses that follow factory-style bends and routing. This helps maintain proper coolant flow path and hose alignment in vehicles that require a shaped upper or lower radiator hose. The hose is listed with a 12 in. trunk height and is made from EPDM, a common material used in radiator coolant hose construction for heat and coolant exposure.

This part cross-references Ford OE numbers such as 3S4Z-8286-AB and 5S4Z-8286-AA for the same application. It is also listed as a replacement for applications commonly associated with Chevrolet Aveo, Chevrolet Aveo5, Pontiac G3, Pontiac G3 Wave, Suzuki Swift+, and Ford Focus cooling system service.
