The new compressor is filled with 180cc (5.0 lmp fl oz) of compressor oil and nitrogen gas. When mounting the compressor on the vehicle, perform the following steps; Tighten: Refrigerant Line Bolt to 27 N m (2.8 kg m/20 lb ft). O-ring cannot be reused. Always replace with new ones. Be sure to apply new specified compressor oil to the O-rings when connecting refrigerant lines. 3. Drive Belt Push the drive belt with the force of 10 kg (22 lbs) and adjust the drive belt tension by tightening idle pulley tension adjustment bolt, until the 8 — 12 mm (0.31 — 0.47 in) deflection of the belt is obtained. Then tighten the pulley center nut. Tighten:
Idle Pulley Center nut to 39 N m (4.0 kg m/29 lb ft). N1A0079E 1. Gently release nitrogen gas from the rear head of the new compressor. Inspect O-rings and replace if necessary. 2. Turn the compressor several times by hand and re- lease the compressor oil in the cylinder. 3. When installing on a new system, the compressor should be installed as it is. When installing on a used system, the compressor should be installed after adjusting the amount of compressor oil. (Re- fer to Section 1D “COMPRESSOR OVERHAUL” for General Information.) Take care not to let the compressor oil flow out. N1A0078E
