All service procedures involving service to the thermal expansion valve (TXV) connections have changed. (Refer to illustration in this bulletin.)
No R-12 Refrigerant (mineral) oil is required during assembly of liquid line-to-TXV connection or suction line-to-TXV connection. These connections should be assembled dry.

The recommended service procedures of applying mineral oil on A/C system O-rings other than the TXV connections should still be practiced and does not change.
