2006 grand caravan 3.8 liter, dual AC system. Replaced condenser, blocked
off leaking rear system, pulled vacuum no leaks. AC has not worked for one
and a half years. Need to add 3 oz of oil, wish to prevent liquid lock of
compressor. I have can of oil that will connect to yellow line of gauge.
Adding total of 3 oz (for condenser and drier).
Drier will be replaced immediately before final vacuum.

1.) Do I manually turn compressor how many turns before or after I
charge system with oil/freon?
2.) Do I add oil prior to Freon or after freon and which side high or low
pressure does the oil flow into through the yellow manifold hose?
I do know not to put amount of freon for a dual system but a single system.
3. ) Does the amount of 3 oz of oil account for any reduction of freon
considering it may be pressurized with freon? It is a very small can.

Additional tips and tricks appreciated. Thank you for your information

 

Oil should be added to the condenser and filter/drier upon installation. Split it up. I only worry about compressor lock if it is added directly to compressor upon compressor replacement in which case a few turns by hand after buttoning it up should suffice.
