Four Seasons A/C Suction and Liquid Line Hose Assembly P/N:56642
Keep refrigerant moving through your air conditioning system with the Four Seasons A/C Suction and Liquid Line Hose Assembly, MPN 66577 — a direct-fit replacement for the 2013-2016 Dodge Dart. This combined assembly routes high-pressure liquid refrigerant toward the evaporator and carries low-pressure suction vapor back to the compressor, with crimped fittings and pre-fitted seals to help it seal at each connection.
Also referred to as an A/C suction line, this assembly is engineered and tested for dependable operation and is backed by Four Seasons' decades of mobile A/C experience. If a leaking, damaged, or corroded original line is the cause of poor A/C performance, this replaces it. See the "Vehicles it fits" section for engine-level fitment details for your Dart.
