FIXED DISPLACEMENT A/C COMPRESSOR

Heating & Air Conditioning
Fig. 200: Denso 10SR17 Compressor

NOTE: Denso 10SR17 shown. Denso 10SR15 similar.

2.7L and 3.5L 5-Passenger models are equipped with the Denso 10SR15 A/C compressor. All 7-Passenger models are equipped with the Denso 10SR17 A/C compressor. Both A/C compressors are a fixed displacement, five double-acting piston, reciprocating swash plate-type compressor (1). Both compressors are clutch operated with suction and discharge ports (2) and have an integral high pressure relief valve (3) located near the rear of the compressor. The A/C compressor is secured to the engine with three bolts.

A label identifying the use of R-134a refrigerant and ND-8 PAG oil is located on each A/C compressor.

VARIABLE DISPLACEMENT A/C COMPRESSOR

Heating & Air Conditioning
Fig. 201: Denso 6SEU16 Compressor

2.0L and 2.4L 5-passenger models use a Denso 6SEU16 clutchless, variable displacement swashplate type A/C compressor (1). This A/C compressor has a total displacement of 160 cubic centimeters (9.7 cubic inches) and a control valve (2) and a high pressure relief valve (3) located on the back cover. The A/C compressor is secured to the engine with three bolts.

A label identifying the use of R-134a refrigerant and ND-8 PAG oil is located on the A/C compressor.

CLUTCH - FIXED DISPLACEMENT A/C COMPRESSOR

Fig. 202: A/C Compressor Clutch Components

NOTE: Typical A/C clutch assembly shown.

The clutch assembly for the Denso 10SR15 and 10SR17 fixed displacement A/C compressors consists of a stationary electromagnetic A/C clutch field coil (4), pulley bearing and pulley assembly (3), clutch plate (2) and shims (7). These components provide the means to engage and disengage the A/C compressor from the engine accessory drive belt.

The A/C clutch field coil and the pulley bearing and pulley assembly are both retained on the nose of the A/C compressor with snap rings (5 and 6). The clutch plate is splined to the compressor shaft and secured with a bolt (1).

HUB AND PULLEY - VARIABLE DISPLACEMENT A/C COMPRESSOR

Fig. 203: A/C Compressor Hub & Pulley Assembly

NOTE: Typical clutchless A/C compressor pulley and drive hub shown.

The non-servicable hub and pulley assembly for the Denso 6SEU16 variable displacement A/C compressor provides the means to drive the A/C compressor using the engine accessory drive belt. The hub and pulley assembly consists of an aluminum drive hub (1) with composite tabs (2) that are positioned between rubber dampeners (3), which are located inside of a composite pulley (4).

The A/C pulley has a bearing (5) which is retained to the nose of the A/C compressor with a snap ring (6). The drive hub and shim (7) are retained to the compressor shaft by use of left handed threads.

HIGH PRESSURE RELIEF VALVE

A high pressure relief valve is located on the compressor cylinder head at the rear of each A/C compressor. This mechanical valve is designed to vent refrigerant from the A/C system to protect against damage to the A/C compressor and other A/C system components caused by condenser air flow restriction or an overcharge of refrigerant.

    Operation
    FIXED DISPLACEMENT A/C COMPRESSOR The Denso 10SR15 and 10SR17 fixed displacement A/C compressors are driven by the engine through an electric clutch, drive pulley and belt arrangement. These A/C c ...
