Note. The following are the operations to be carried out after removing the compressor.
Remove the fill plug (1).
Turn the compressor over and let the oil flow out of it.
Install plugs at the compressor inlet and outlet.
Position the compressor vertically (muff up).
Rotate the whole knot (2) two dozen turns (this helps to drain the oil in the head).
Remove the plugs.
Let the oil flow out.
Measure the amount of oil collected.
Compare all collected oil with the amount recommended by the manufacturer.
Note. Some variable amount of oil remains in the A/C compressor (depending on compressor type).
Refill with the same amount of oil that was collected (through the filling hole).
Install drain plug (1) (new seal and clean bearing surfaces).
Tighten the plug to 20 Nm.
Install plugs at the inlet and outlet of the compressor (when working on the cooling circuit).
Disconnect the battery.
Extract the refrigerant from the air conditioning system using the station.
