Product Details

Gates 12496 is a molded HVAC heater hose intended for reservoir-to-pipe routing on the 2013-2016 Dodge Dart. The formed profile helps match the original hose path, which is important in compact engine bays where straight hose sections can create routing issues or stress at the connections. If you are replacing a worn Dodge Dart heater hose, Gates 12496 provides the molded shape and size details needed for a direct service replacement.
