Gates 22509 Radiator Coolant Hose - Lower or Lower Right

Gates 22509 Molded Coolant Hose

Gates 22509 is a molded radiator coolant hose built to OEM-quality specifications for lower cooling-system service. Made from EPDM, it uses a molded shape with 1.45 in. (37 mm) inside diameters at both ends and a 15 in. (381 mm) centerline length for a direct replacement profile.

The Gates Molded Coolant Hose line covers upper, lower, bypass, heater, and other coolant routing needs. This part is a practical replacement for Subaru Legacy, Subaru Outback, BMW 318i, BMW 318is, BMW 318ti, BMW Z3, Lincoln LS, and Jaguar S-Type lower hose applications where the original hose shape and routing matter.

Common Replacement Uses

• Cracked or hardened lower radiator hose
• Coolant seepage at a formed hose section
• Incorrect hose routing after cooling-system repair
• Loss of coolant flow from a deteriorated molded hose
• Fitment issues when a straight hose will not follow the factory path

Installation Notes

Verify hose routing, end diameters, and centerline length against the original part before installation. Inspect adjoining necks, clamps, and coolant passages for wear or corrosion, and confirm the vehicle’s oil-cooler and HVAC configuration where noted in fitment. Gates 22509 is a molded replacement hose, so correct orientation during installation is important for proper routing.
