Four Seasons A/C Refrigerant Suction Hose P/N:56231
Move low-pressure refrigerant vapor back to the compressor with the Four Seasons A/C Refrigerant Suction Hose 56748, a suction line hose assembly that installs as a direct-fit replacement on the 2012-2015 Honda Civic (see the Buyer's Guide tab for engine-level fitment). It carries the cool, low-pressure refrigerant from the evaporator outlet back to the compressor as part of the air-conditioning circuit — the routing a cracked, corroded, or leaking original hose can no longer seal.
If a leaking or damaged suction hose is the source of your lost cooling, this assembly replaces it. Have the system evacuated and recharged to the correct refrigerant and specification after installation.
