I'll try to make sense out of this------ They say that a A/C service center machine will pull out all the refrigerant and oil as well as separate the 2 components. They say to take note of amount of oil removed (so as to add that same amount when recharging takes place). But that bothers me. My thinking, is if the system had lost *any* amount of refrigerant and/or oil, you wouldn't know the exact amount to add based on the recovered amount. It says new compressors come from the factory serviced with some oil. The say to rotate the compressor pulley to aid in removal of the oil within it. The drawing shows the oil being removed from and added to the smaller of the 2 ports on the compressor. But they tell you to pour it out into a measurement container (to see how much they had added, then put it back in). If *no* oil came in the new compressor, they say to add 2 ounces to it, then >>>> Rotate the compressor pulley several rotations to lubricate all the things in it, then mount it in the car. Using new washers (*without* adding any oil/lubricant to them), reattach the suction/discharge pipes an torque to 16 lb ft. Then reconnect the electrical connector.
They just say (after getting all the necessary things out of the way), to remove the upper radiator support brackets, and tilt the radiator and condenser towards the engine as necessary to gain access to the dryer located vertically on the passenger side of the condenser. When evacuating and recharging, add oil quantity as shown below, minus what ever amount was put back into the compressor.
Use PAG oil---- Total system PAG oil capacity is 3.3 to 4.7 ounces. HFC R-134a quantity is 20.5 ounces. If I see errors , I'll correct on a re-read thru
