Detailed Description

Gates 18112 is a molded HVAC heater hose engineered to follow the OE routing used in compact engine compartments. Its EPDM material supports heat and fluid exposure in heater and coolant circuits, while the molded shape helps maintain the correct path between connection points. This makes it a direct replacement choice for applications that require a small I.D. molded coolant hose with a 21.9-inch centerline length.

This part cross-references Anchor 10112 for the same application. It is listed for 1995-2002 Kia Sportage, Engine To Throttle Body; 1994 Geo Metro, Pipe To Throttle Body and Throttle Body To Pipe; 1994 Pontiac Firefly, Pipe To Throttle Body and Throttle Body To Pipe; 1993 Geo Metro, Pipe To Throttle Body; 1989-1992 Chevrolet Sprint, Throttle Body To Engine; 1989-1992 Geo Metro, Throttle Body To Engine; 1992 Suzuki Swift, Throttle Body To Engine; and 1989-1991 Pontiac Firefly, Throttle Body To Engine.

Common Uses

• Replacing a cracked or leaking heater hose in the Kia Sportage
• Restoring coolant flow in Geo Metro and Pontiac Firefly throttle body routing
• Addressing hose collapse, hardening, or heat damage in compact engine bays
• Repairing a worn molded coolant hose on Chevrolet Sprint or Suzuki Swift applications
• Maintaining proper HVAC and radiator hose routing where OE-style shape matters

Installation Notes and Tips

Verify end diameter, centerline length, and molded routing before installation. Confirm the vehicle position listed for your application, such as Engine To Throttle Body or Throttle Body To Engine, and compare the hose path to the original part before removal. Because this hose is molded, correct orientation is important for proper fitment in tight spaces.

Quality Assurance

Gates is known for OE-style hose construction across cooling and HVAC service parts. The 18112 molded heater hose is built to match the shape and dimensions needed for the listed applications, including Kia Sportage, Geo Metro, Pontiac Firefly, Chevrolet Sprint, and Suzuki Swift models.
