Detailed Description

The Gates Molded Coolant Hose line is engineered for vehicles that use application-specific coolant hose assemblies rather than universal hose lengths. Part number 52428 includes molded features and integrated connection points that align with the original hose layout, including a female quick connector and other OE-style components identified in the design. For Chevrolet Colorado and GMC Canyon heater inlet service, this hose supports the factory routing and connection style used in the cooling and HVAC system.

Gates 52428 is a practical replacement when the original molded hose has cracked, softened, or no longer seals properly at the connection points. The molded shape helps preserve the intended hose path, while the EPDM and plastic construction is selected for coolant exposure and underhood use. This part cross-references Dorman - OE Solutions 626-745 for the same application.
