* Flush, with an approved solvent, to Clean the system*
* Replace the Accumulator/Drier or Orifice tube
* Replace manifold sealing washers or O-rings
* Use a Vacuum Pump (20+ minutes) to remove moisture.
* Add the proper amount and type of oil. Check OEM spec
* Rotate compressor hub 12 times to oil the shaft seal
* Place a strong external airflow into the condenser
* Check OEM specifications for correct refrigerant charge
* Charge with VAPOR refrigerant and with A/C and engine off.
* Do a leak test and check voltage at clutch coil
* Check belt tension and alignment
* Check system operation at 1500 RPM and mid-blower speed
* Use gauges to check the system pressures.

*Only if the condenser is the type that can be flushed.
