REFRIGERANT OIL & R-134a REFRIGERANT CAPACITY
Only NEW, moisture-free refrigerant oil should be used in the air conditioning system. This oil is highly refined and dehydrated so moisture content is less than 10 parts per million. The oil container must be tightly closed at all times when not in use, or moisture from the air will be absorbed into the refrigerant oil.
DISCHARGING SYSTEM
Discharge A/C system, using approved refrigerant recovery/recycling equipment. Always follow recovery/recycling equipment manufacturer's instructions. After refrigerant recovery process is completed, the amount of compressor oil removed must be measured and the same amount added to A/C system.
DISCONNECTING LINES & FITTINGS
After system is discharged, carefully clean area around all fittings to be opened. Always use 2 wrenches when tightening or loosening fittings. Some refrigerant lines are connected with a coupling. Special tools may be required to disconnect lines. Cap or plug all openings as soon as lines are removed. Remove caps until connections of lines and fittings are to be completed.
CONNECTING LINES & FITTINGS
Note. All R-134a based systems use 1/2"-16 ACME threaded fittings. Ensure all replacement parts match the connections of the system being worked on.
Always use a new gasket or "O" ring when connecting lines or fittings. Coat "O" ring with refrigerant oil and ensure it is not twisted during installation. Always use two wrenches to prevent damage to lines and fittings.
PLACING SYSTEM IN OPERATION
After component service or replacement has been completed and all connections have been made, thoroughly evacuate system with a vacuum pump. Charge system with proper amount of refrigerant and perform leak test. See the REFRIGERANT OIL & R-134a REFRIGERANT CAPACITY table for system capacities. Check all fittings that have been opened. After system has been leak tested, check system performance.
Note. Most compressors are pre-charged with a fixed amount of refrigerant (shipping) oil. Drain compressor oil from new compressor and add refrigerant oil to new compressor according to amount removed from old compressor. Always refer to underhood A/C specification label or A/C compressor label while servicing A/C system.
Except SLX
A new compressor is shipped with refrigerant oil. Drain and measure oil from old compressor. Remove refrigerant oil from new compressor equal to difference between amount drained from old compressor and amount shipped in new compressor. If new compressor is shipped without refrigerant oil, add same amount of oil that was drained from old compressor. If any other major components are replaced, add refrigerant oil as specified. See REFRIGERANT OIL CAPACITIES TABLE (10-CYL).

| (1) If new compressor is shipped without refrigerant oil, add same amount of new refrigerant oil to new compressor that was drained from old compressor. DO NOT subtract more than 1.7 ounces of refrigerant oil from new compressor. After adding oil to compressor, rotate compressor 10 times before operating system to prevent compressor damage. | ||

- Before checking and adjusting oil level, operate engine at 1200 RPM. If compressor cannot be operated, go to step 5). Set controls at maximum cooling and high blower motor speed for 10 minutes to return oil to compressor.
- Stop engine. Discharge A/C system. See «SERVICING»(/acura/integra/iii-1993-2001/remont/general-servicing-all-makes/#ac-compressor-refrigerant-oil-checking) PRECAUTIONS. Measure the amount of oil drained/discharged into refrigerant recovery/recycling equipment.
- Remove compressor from vehicle. Drain compressor oil from compressor drain plug and measure oil amount. Add this amount to amount drained in step 2) to obtain total amount drained.
- Fill compressor with total amount drained, using new oil. If any major components of the system were also replaced, determine the amount of additional oil needed. See «REFRIGERANT OIL CAPACITIES (ZEXEL ROTARY VANE)»(/acura/integra/iii-1993-2001/remont/general-servicing-all-makes/#ac-compressor-refrigerant-oil-checking) for specified amount.
- Remove compressor refrigerant oil drain plug (if equipped), drain and measure oil in old compressor. Drain and save shipping oil from new compressor (if present). Add same amount of new shipping oil as was removed from oil compressor to new compressor. If receiver-drier is being replaced add an additional 0.2 ounce to compressor.
