During Component Replacement
When replacing other components of the air conditioning system, measured quantities of the specified refrigerant oil should be added to the component to make sure that the total charge in the system is correct before the system is operated.
Clean refrigerant oil should be poured directly into the replacement components as follows:
A/C evaporator core (19860): add 90 ml (3 oz).
A/C condenser core (19712): add 30 ml (1 oz).
Accumulator: drain oil from removed accumulator/drier. Add same amount plug 60 ml (2 oz) of clean refrigerant oil to new accumulator.
If any other component such as an A/C evaporator core orifice (19D990) or a hose is replaced, no additional refrigerant oil is necessary unless a hose bursts with a fully charged system. Then, the addition of refrigerant oil may be necessary with the amount to be determined by the technician. The suction accumulator-drier should also be replaced under these circumstances.
That is a general spec I would add 1 oz to the condenser and 2 oz to the accumulator... If I found the expansion tube dry I may add a extra oz... They also sell o-ring kits I would buy a kit just in case I needed a o-ring not supplied with the parts..
You can make a mess removing the expansion tube sometimes you get lucky and can pull them with needle nose pliers... It takes a special tool to remove them and sometimes that does not work... DON'T BREAK IT OFF :!: If you go after it and it does not pull out EZ just leave it be for now.
