Gates 18485 HVAC Heater Hose - Pipe-1 To Auxiliary Heater Pipe-1
Gates Molded Heater Hose 18485 Overview
The Gates 18485 molded heater hose is an OEM-style coolant hose built for tight engine bays where a straight hose will not route correctly. It is formed to match factory routing and is suitable for coolant, water, and air applications, with marine application approval as noted by the manufacturer.
Compatible with 2004-2007 Dodge Durango and 2007 Chrysler Aspen heater hose routing, this molded EPDM hose supports the pipe-1 to auxiliary heater pipe-1 connection.
