Product Details

Gates 22820 is a molded coolant hose designed for Volvo cooling system service where the lower hose follows a specific formed path. The hose measures 1.25 inches inside diameter at both ends and 36.5 inches centerline length, helping it match the original routing used on the vehicle. As part of the Gates Molded Coolant Hose product line, it is built for applications that require integrated OE-style features rather than a universal straight hose.

This part cross-references Dayco 72725 for the same application. If you are replacing a lower radiator hose on a Volvo S40 or Volvo V40, part number 22820 provides a direct-fit option that aligns with the factory cooling layout.

Common Cooling System Issues

• Cracked or split lower radiator hose
• Coolant leaks at the hose body or connection points
• Softening, swelling, or deterioration from heat and age
• Restricted coolant flow caused by hose collapse or deformation
• Service issues related to a worn bleeder valve assembly

Installation Notes

Verify the vehicle year, model, and lower hose routing before installation. Confirm the hose diameter and molded shape match the original part, and inspect adjoining clamps, fittings, and coolant connections for wear before reassembly. After installation, refill and bleed the cooling system according to the vehicle service procedure to remove trapped air.

Quality Assurance

Gates is a recognized aftermarket supplier of modular coolant hose assemblies, and this hose is manufactured to application-specific OE-style specifications for the listed Volvo fitments. Part number 22820 is built to follow the original cooling system layout used on the compatible S40 and V40 applications.
