# A/C System PAG Oil Accumulation at Set Screw on Rear Head of A/C Compressor

Subject: | A/C System PAG Oil Accumulation at Set Screw on Rear Head of A/C Compressor (Wipe Off Excess Oil at Set Screw)

Models: | 1999-2000 Saturn S-Series vehicles equipped with A/C (RPO code C60)

| All 2000 Saturn L-Series vehicles

### Condition

During pre-delivery inspection (PDI) at Saturn Retailers, a small amount of A/C system PAG oil may be noticed at the rear head of the A/C compressor around the bottom of set screw (refer to illustration in this bulletin). This may also be present on service replacement compressors.

### Cause

An excessive amount of PAG oil may have been used to lubricate the set screw O-ring during installation of set screw into the rear head of the A/C compressor. This accumulation of PAG oil from assembly is not an indication of an A/C system leak.

### Correction

Wipe off excess PAG oil at the set screw location on the rear of the A/C compressor if necessary.
