(2) Removing Compressor Assembly

Compressor
1. Discharge the refrigerant from the system. (Refer to
"Discharging the Refrigerant": See page 10-S16.)
2. Disconnect the low pressure pipe (suction) (8) and high
pressure pipe (discharge) (7) from the compressor (2), then cap
the open fitting immediately to keep moisture out of the system.
3. Disconnect the 1P connector (1), 2P connector (6) and the
ground lead (4).
4. Remove the air conditioner belt (3).
5. Remove the bolts (5) and the compressor (2).
(When reassembling)
• After reassembling the compressor, be sure to adjust the air
conditioner belt tension and recharge the refrigerant to the
system. (Refer to "Charging the Refrigerant": See page
10-S16.)
• Apply compressor oil (DENSO CO. ND-OIL8 or equivalent) to
the O-rings and take care not to damage them.
(When replacing compressor)
• When replacing the compressor with a new one, meet the oil
amount with old one.
• Readjust the belt tension. Refer to page G-27.
