Detailed Description

Gates 22343 is a molded radiator coolant hose engineered for lower hose routing on select 1998-2002 Chevrolet Cavalier and 1998-2002 Pontiac Sunfire models. Its molded shape and branch configuration support the factory-style coolant path, helping maintain proper hose routing in the engine bay. This part cross-references Dayco 71944 for the same application.

As part of the Gates Molded Coolant Hose line, this hose is built around vehicle-specific dimensions and integrated features rather than a universal cut-to-fit design. The result is a direct replacement option for cooling system service on the Chevrolet Cavalier and Pontiac Sunfire platform when the original lower hose requires replacement. Gates 22343 is also referenced by Bosch 62277.

Common Uses

• Replacing a cracked or deteriorated lower radiator hose
• Restoring coolant flow after hose swelling or softening
• Correcting leaks at a molded hose branch section
• Replacing a hose that no longer follows the factory routing
• Servicing cooling system wear on Chevrolet Cavalier and Pontiac Sunfire models

Installation Notes

Verify the hose routing, end diameters, and branch layout against the original part before installation. This hose is listed for lower position applications on 1998-2002 Chevrolet Cavalier and 1998-2002 Pontiac Sunfire models, so confirm the vehicle year and cooling system configuration before ordering. Inspect adjoining clamps, fittings, and mating surfaces for wear or corrosion during service.
