SUBJECT:
Updated Service Information for Service Procedures Involving the Liquid Line-to-TXV Connection or Suction Line-to-TXV Connection
MODELS AFFECTED:
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 0-rings other than the TXV connections should still be practiced and does
not change.
