Four Seasons A/C Refrigerant Suction Hose P/N:66696
Four Seasons 56818 a/c refrigerant suction hose for the 2013-2018 Acura RDX carries refrigerant on the low-pressure suction side of the A/C system back to the compressor.
Oily residue on the hose or its fittings, a cracked or bulging hose, or weak cooling can mean the suction hose needs replacing. Before you replace it, rule out leaks at the compressor, condenser and service ports, because weak cooling has more than one source.
This hose fits the 2013-2018 Acura RDX.
