Product Details

Gates 18010 is a molded coolant hose designed to match the shape and routing demands of modern and older compact engine layouts. The molded profile helps maintain proper hose alignment in HVAC and cooling circuits, while the EPDM material is commonly used in heater hose service for temperature and fluid exposure resistance. This hose is a practical choice when replacing a formed heater hose on vehicles such as the Mazda Miata, Subaru Forester, or Honda CR-V, where the original hose path is critical to fitment.

This part cross-references Dayco 86500 and Dorman - HELP 74216 for the same application.

Common Problems It Can Address

• Cracked or hardened heater hose material
• Coolant leaks at a molded hose section
• Poor hose routing in tight engine compartments
• Restricted flow caused by a deteriorated hose
• Replacement needs for throttle body, thermostat, or auxiliary heater hose routing

Installation Notes and Tips

Verify end diameter, centerline length, and molded shape against the original hose before installation. Confirm the routing position listed for your vehicle, especially on applications marked throttle body to thermostat, engine to pipe, or auxiliary heater connections. Inspect adjoining fittings, clamps, and pipe ends for wear or corrosion before installing the new hose.
