I looked everywhere on how to adjust the A/C belts and found nothing. I have the A/C compressor underneath the alternator. So I removed the Alternator, (lots of fun) and after adjusting the A/C belts I see that it is not required removing the alternator since the A/C belt adjuster is available underneath the Alternator. I will send photo. I hope this will save someone a lot of time.
