A rattling noise may develop from the AC belt tensioner. This can be caused by an internal fault with the AC compressor, AC performance may also be diminished when this occurs. Our technicians tell us that replacing the AC compressor will commonly correct this concern.

    Squalling while engine is running. Sometimes quieter when engine has been running long periods of time. Replaced both tensioners, no joy. Narrowed down to AC Compressor pulley as increased tension makes squall very quiet, reduced tension makes lots of noise. No pulley/clutch assemblies sold independent of entire AC Compressor. AWESOME!

    Checked coolant level in AC system and found it to be normal. Local repair shop listened to problem and made correct diagnosis. Replaced AC Compressor

  • Burning smell and squealing noise. Took to dealer and they diagnosed as A/C Compressor failure. Quote $600 just for new compressor. Opted to just disable by cutting belt.
