Detailed Description

Gates part number 18554 is a molded coolant hose designed to match the shape and routing of the original hose in applications where space is limited. The EPDM material is selected for heater and coolant service, while the molded profile helps maintain proper hose alignment between the radiator and reservoir. This makes it a practical replacement for Toyota Corolla and Toyota Matrix models that require a radiator-to-reservoir molded heater hose. This part cross-references CSF 10554 for the same application.

What It Helps Address

• Cracked or aged coolant hose material
• Improper hose routing in tight engine compartments
• Coolant seepage at worn hose connections
• Loss of hose shape from heat and age
• Replacement needs for radiator-to-reservoir hose service
