Product Details

This molded heater hose is intended for radiator-to-reservoir routing where a formed hose is required. The 26.2-inch centerline length and 7 mm end inside diameter support applications that need a precise molded path in confined spaces. Gates 18385 is also listed for coolant, water, and air use, giving it broader service coverage within HVAC and cooling-system plumbing. Cross-reference part numbers include Davico Mfg 18385 and Dixie Electric Ltd 10385 for the same application.

Common Uses

• Replacing a cracked or hardened molded coolant hose
• Restoring radiator-to-reservoir flow in a cooling circuit
• Addressing leaks at a formed heater hose section
• Replacing a hose that no longer holds its molded shape

Installation Notes

Verify hose routing, end diameter, and centerline length before installation. This part is molded for specific routing, so match the existing path and connection points on the vehicle. Confirm the application against the vehicle’s cooling and HVAC hose layout before final assembly.

Quality Assurance

Gates manufactures this hose as an OEM-style molded replacement for compact engine bay applications. Part number 18385 is built to Gates’ molded hose specifications for fitment-focused service work.
