Keep in mind when I started this video I had no refrigerant in the system. If you still have refrigerant in the system you'll want to have an AC service recover that refrigerant into its own bottle that you/they can then turn into a disposal facility. Any automotive shop that works hvac can assist you with the process of evacuating any existing refrigerant in the system if you do not have a license/equipment.
Also recommend replacing the seals on the high and low side connections to the compressor (the compressor I bought came with new seals but you can also order them separately if needed.

Was your a/c system fully charged when you started to vacuum down the system?
No, there was no refrigerant in the system when I started this job. Although evacuating the system is similar, the only difference is you'd capture the refrigerant into a bottle. That's a little trickier to DIY. If you have a buddy that has the equipment or an AC shop near by they can recover the refrigerant for you.
Great video.
Great step by step.. I have a couple suggestions.. but wouldn't criticize here, only if I could message you directly
I don't have a way for you to message me directly on RUclips. At least I don't know of a way. Feel free to reply in the comments though I don't mind. Whatever suggestions you might have would hopefully help out others as well
Great video! Would've been nice to see you actually purge/evacuation of the preexisting refrigerant for thoroughness unless I missed it somehow... Not sure why you wouldn't show that part as it's important i would think. Isn't the refrigerant bad for the environment? Over all great video! Thank you!
That is a great point. In my video description I explain this concern. I've also expanded it after reading your comment. Thanks for the feedback and thank you for watching
Did you replace your dryer filter and if so where was it?
I did not. I believe it's build into the condenser
Very good video! At the beginning, when vacuuming the lines, do you need open the the high side as well or just low side?
Thank you. Yes I usually do vaccum both sides simultaneously.
But both lines need to be open, correct??
@@noeperez5052 it's ok to vaccum with both lines open.
I have a 2015 duramax. My clutch is burnt. I found a replacement clutch assy online and diving into it Thursday. Any reason you didn't just replace the clutch and replaced the whole compressor?
@cheramiefarms2044 well the main reason was the local Oreilys doesn't carry the clutch assembly so I would have had to order the part and wait. I had the time, and time is money as they say. Other reasons, the clutch in my case flew off my truck. Legit just fell off and disappeared which means the center bolt that holds it on must have backed off and disappeared with it. So I would have had to source a replacement bolt. Not the biggest issue in the world but this is about a 10 yr old truck with over 200k miles so figured I might as well just swap it out now while I'm at it.
I’m in the same boat. 300k miles, the center bolt is missing but everything still there. Going to try to source a center bolt and hopefully just replace the clutch!
@@cheramiefarms2044 let me know how it goes!
@@scrappynotcrappy having a hard time getting the clutch off. The puller doesn’t fit the small bolt hole. Not sure
@cheramiefarms2044 dang, I would have thought it would have come right off with your fingers considering how mine just fell off while I was driving.
Mine ac compressor just gave out on my 15’ Sierra 2500 with the 6.0, now i can remove old and install new but as far as recharge it im not familiar with that, also since I don’t have to drain it before removing the bad one would you work on a vehicle where the owner replaced ac compressor and you just needed to recharge it ?
If I didnt know how much oil was in the compressor that was installed personally I'd ask whoever installed it if the compressor came with oil or not. If it did then I'd just vaccum it and charge it. If it didn't or they aren't sure then I'd remove it and make sure it has the recommended amount of oil in it.
If I bought a compressor prefilled, do I need to add PAG 46 anywhere else?
If all you're replacing is the compressor all you have to do is ensure it has the same amount of oil as the last compressor did. Basically think about it like this, if you removed a compressor you also removed any oil that's contained in that compressor from the system. So you'll want to measure how much oil comes out of your old compressor once you remove it so you can be sure that the same amount of oil is being replaced.
You want your new compressor to have the same amount of oil as the old one. So drain the old one and measure. Then drain the new one and measure. Then refill the new one accordingly
Unless you're system has been overfilled with oil in the past this is a tried and true method. If you're in doubt don't worry too much about it. Just go with the recommended amount of oil for your compressor and you'll be fine.
