Accumulator

Print

See Figures 1 and 2

Found on 1994-96 models, the accumulator is mounted in the engine compartment between the evaporator coil outlet tube and the compressor inlet. Refrigerant enters the accumulator as low pressure vapor through the inlet tube. Oil-laden, liquid refrigerant falls to the bottom of the canister, which acts as a separator. A dessicant bag is mounted inside the accumulator canister to absorb any moisture which may be in the refrigerant system.
