Compressor and Block Fitting
WARNING: This page is about a different car, the 2003 Pontiac Vibe. However, it is still accessible from the selected car via links, so may be relevant.
A worn shaft seal often causes compressor gas leaks. A small amount of compressor oil leakage from the shaft seal is normal. Replace the compressor only when a large leak is detected. At times, an oil leak can be detected visually. A gas leak check will require a gas leak detector.
- For at least 15 seconds, blow shop air behind the compressor clutch pulley and in front of the compressor clutch pulley.
- Probe the compressor area. If the detector goes to a solid alarm, a leak is present.
