Gates 19566 HVAC Heater Hose - Heater Outlet

Gates Molded Heater Hose 19566 Overview

Gates 19566 is a molded heater hose built for tight engine bays where a straight hose will not route cleanly. This OEM-style coolant hose uses EPDM construction and a factory-molded shape to support coolant, water, and air transfer in the heater outlet circuit.

Compatible with 2004-2012 Mitsubishi Galant, heater outlet, and 2006-2012 Mitsubishi Eclipse, heater outlet, this molded heater hose follows the routing needed in compact engine compartments. The Gates Molded Heater Hose line focuses on OE-style fit and formed bends for service replacement work.
