Four Seasons A/C Refrigerant Discharge Hose P/N:66765
Four Seasons 56596 a/c refrigerant discharge hose for the 1993-1997 Mazda 626 and other vehicles is a discharge line hose assembly that carries refrigerant from the A/C compressor.
A/C that blows warm, oily residue around the hose fittings or a refrigerant leak can mean this hose is worn, though a failing compressor or condenser can also be behind them, so find the cause before replacing anything. If the discharge hose is the cause, this assembly replaces it.
It also fits the 1993-1997 Mazda MX-6.
