Subject: | Updated Service Information for Service Procedures Involving the Liquid Line-to-TXV Connection or Suction Line-to-TXV Connection

Models: | 1991 - 2000 Saturn S-Series vehicles equipped with A/C (RPO code C60)

### Purpose

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.

This new recommended practice should replace any previous recommendations involving TXV connections found in the 1991 - 2000 HVAC Service Manuals.

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.
