Refrigerant Oil

NOTE: To maintain the original total oil charge, it is necessary to compensate for the oil lost by adding oil to the system with the replacement part.

For the A/C evaporator core, add 89 ml (3 ounces) of clean refrigerant oil to the suction accumulator/drier inlet tube whenever the A/C evaporator core is replaced. This will compensate for the refrigerant oil lost in the replaced A/C evaporator core.
