Detailed Product Description

This Gates molded coolant hose is shaped for specific cooling-system layouts and is listed across a wide range of import and domestic applications. It is used on upper radiator hose routes, lower radiator hose routes, and heater or HVAC coolant paths where a molded hose profile is required. For fitment-based searches, this part is commonly referenced for Volkswagen Passat, Volkswagen Jetta, and Hyundai Tucson cooling system service.

Part number 21942 is also cross-referenced as Continental 60083 for the same application. The molded profile and EPDM material support replacement of aging hoses that have softened, cracked, or lost their original shape.

Common Problems This Hose Can Address

• Coolant leaks from cracked or deteriorated hose rubber
• Collapsed or softened hose sections that restrict coolant flow
• Incorrect hose routing after a previous repair
• Heat-related swelling, splitting, or hardening at the hose body
