Gates 18200 HVAC Heater Hose

Gates 18200 Molded Heater Hose Overview

The Gates 18200 molded heater hose is a factory-shaped, OE-style coolant hose built for tight engine bays and smaller routing spaces. Made from EPDM, it is suitable for coolant, water, and air service, and it is also approved for marine applications.

Gates Molded Heater Hose products are formed to follow the original hose path, helping maintain proper routing in applications where a straight hose will not match the factory layout. This molded design supports clean fitment in compact engine compartments found on vehicles such as the Honda Civic, Nissan Quest, and Chrysler Intrepid.

Detailed Description

Gates 18200 is a molded coolant and heater hose designed to follow the original equipment path in applications where space is limited. Its EPDM material and molded profile make it a practical replacement for heater, coolant, and air routing needs, including marine use where specified. This part cross-references Bosch 18200 for the same application.

Compatible With 1984-1985 Honda Civic, Intake Manifold To Thermostat; 1988-1991 Honda Civic, Intake Manifold To Pipe-3 and Throttle Body To Engine; 1993-1998 Nissan Quest, Pipe-6 To Pipe-7; and 1993-1998 Mercury Villager, Pipe-6 To Pipe-7. The Gates 18200 is also listed for select Chrysler, Dodge, Mazda, and Mitsubishi applications, including the Chrysler Intrepid and Dodge Intrepid.

What It Helps Address

• Cracked or heat-aged molded heater hose routing
• Coolant leaks at a formed hose section
• Poor hose alignment in tight engine compartments
• Replacement needs for OE-shaped heater and coolant hose paths
• Routing issues on compact intake-manifold and throttle-body connections

Installation Notes and Tips

Verify end diameters, centerline length, and routing before installation. Compare the original hose shape to the molded profile to confirm the hose follows the factory path without kinking or tension. For 1985 Honda Civic applications, the fitment notes indicate early use and cut-to-fit service, so confirm the vehicle-specific routing before final installation.

Quality Assurance

Gates manufactures this molded heater hose as an OE-style replacement part for applications that require accurate shape and dependable material selection. The 18200 part number is supported by listed interchange references and fitment data for multiple vehicle platforms.
