Fixed Displacement A/C Compressor

WARNING: This page is about a different car, the 2014 Dodge Journey. However, it is still accessible from the selected car via links, so may be relevant.

The Denso 10SR17, 10SRE18 and 10SRE20 fixed displacement A/C compressors are driven by the engine through an electric clutch, drive pulley and belt arrangement. These A/C compressors are lubricated by refrigerant oil that is circulated throughout the refrigerant system with the refrigerant. Refer to OIL, REFRIGERANT, STANDARD PROCEDURE .

The A/C compressors draw in low-pressure refrigerant vapor from the A/C evaporator through the suction port, then compresses the refrigerant into a high-pressure, high-temperature refrigerant vapor, which is pumped to the A/C condenser through the compressor discharge port.

CAUTION:

Be certain to adjust the refrigerant system oil level when replacing an A/C compressor. Failure to properly adjust the refrigerant oil level can prevent the A/C system from operating as designed and can cause serious A/C compressor damage.

The Denso fixed displacement A/C compressors cannot be repaired and must be replaced if inoperative or damaged. The A/C clutch, pulley and bearing assembly, and clutch coil are available for service if inoperative or damaged. If an internal failure of the A/C compressor has occurred, the A/C receiver/drier must also be replaced. Refer to DRIER, A/C RECEIVER, REMOVAL .
