Fig. 8 Oil Charge Table. XT Models:





The oil used to lubricate the compressor circulates in the system with the refrigerant gas while the compressor is engaged. If a considerable amount of refrigerant gas is lost, the oil charge in the system will have checked. To check the oil level, proceed as follows:
1. Set A/C controls for maximum cooling and high blower speed.
2. Operate engine at 1,000-1,500 rpm for approximately 10 minutes to return oil to the compressor.
3. Stop engine, then slowly discharge refrigerant from system.
4. Remove compressor from vehicle.
5. Drain oil from suction port of the compressor into a premeasured container. On Diesel Kiki models, drain oil through drain plug. On Calsonic models, drain oil through suction and delivery ports, then rotate the clutch hub two or three times to completely drain oil.
6. Refer to Fig. 8 for amount of oil to be added or removed. If replacing the compressor, a new compressor contains 150cc of oil, drain 80cc of oil from the new compressor or adjust the amount of oil to the same of the removed compressor.
7. If adding oil to the compressor, pour the premeasured oil into the suction port of the compressor with the aid of a funnel.
8. Install compressor, then evacuate and recharge air conditioning system to specifications.
