Gates 12137 HVAC Heater Hose - Throttle Body Inlet

Gates Molded Heater Hose for Tight Engine Bays

The Gates 12137 molded heater hose is built for compact engine compartments where a straight hose will not route correctly. This factory-molded, OE-style coolant hose is shaped for the throttle body inlet on select Dodge, Mitsubishi, and Mitsubishi Mirage G4 applications.

Made from EPDM and plastic, this molded coolant hose is suitable for coolant, water, and air service, and it is approved for marine applications. The Gates Molded Heater Hose line focuses on precise routing and fitment for smaller, tighter-fitting engine layouts.
