Product Line Details

Gates Molded Coolant Hose products are built for upper, lower, bypass, heater, and other coolant hose applications.

Detailed Description

This radiator coolant hose is a molded replacement for upper cooling-system routing on select Kia Optima and Hyundai Sonata models. The EPDM material is commonly used in coolant service for its resistance to heat and coolant exposure, while the molded profile supports a direct-fit replacement where a formed hose is required. Gates 24821 is a practical choice when replacing a worn or leaking upper radiator hose on the specified vehicles.

This part cross-references BBB Industries 17479 for the same application.

Common Issues This Hose Can Address

• Coolant seepage from a cracked or aged upper hose
• Softening, swelling, or collapse of the original hose
• Improper hose routing after prior repairs
• Loss of cooling-system pressure at the hose connection
• Replacement needs on a damaged molded radiator hose

Installation Notes and Tips

Verify hose routing and end diameters before installation. Inspect the mating necks, clamps, and nearby cooling-system components for wear or corrosion, and replace any damaged parts as needed. After installation, refill and bleed the cooling system according to the vehicle service procedure and check for leaks at operating temperature.
