Installation

Installation procedure is the reverse of removal, except for the following:

Caution: The new A/C compressor is pre-filled with the total amount of oil used in the A/C system. Oil needs to be removed so that the amount of oil in the new A/C compressor equals the amount of oil in the old one. To do this, use a digital scale to weigh both the old and new A/C compressors. Turn the new one upside down to drain a small amount of oil, then re-weigh it. Repeat this process until the new A/C compressor weighs the same as the old one.

  • Transfer the NVH padding to the new compressor.
  • Recharge the A/C system.
