Awesome instructional video. Thank you so much for taking the time to post it. I am a lay person whom just had the compressor replaced on my Taho. This video helped me to identify that the part had indeed been replaced.

what was the purpose of hooking up the vacuum after installing everything? is it necessary ?

[APDTY]

@sofujun Yes, Drawing down the vacuum is necessary after opening the ac system. This does two things. It removes the air from the system and removes the moisture from the system, both of which can have negative and destructive effects on the AC system. Failure to draw vacuum can cause the high pressure to run too high and shorten the life of your compressor, as well as make the system work less efficiently. Thanks!
