Fixed Displacement A/C Compressor

WARNING: This page is about a different car, the 2016 Dodge Journey and 2015 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 .
