Oh, one last thing....don't get the refrigerant with oil or stop leak in it. Just get the regular stuff.

Thanks for the awesome write up. When I add the pag oil do I subtract that amount from the total amount of refrigerant Ill be adding to the system? My current (failed) compressor takes 8.0oz of oil. I'm sure the new one is close to the same amount but ill double check tonight. And my system says it takes. 3.25lbs of refrigerant. After doing the whole r134a will only need 85% of what r12 would use it looks like ill need 44.2oz of refrigerant if I don't subtract the pag oil don that.

Another thing you said to pour the pag oil into the compressor I see what we gave this at my Walmart. Do they make just straight oil that's not in a compressed can like this? I'll check napa tomorrow.

If it were me, I would put in all new oil. My local stores have 8oz bottles that are not compressed, just pour bottles that are $9.

As far as the 85% thing, I am not sure where you heard that. If I somehow led you to believe that, I apologize. I didn't mean to. I was simply saying to add as close to the refrigerant amount without going over. If you can get a 44oz can, do that. You should be able to find a 22oz bottle. Just put in two of those and you are set.

Also, you do not subtract the 8oz of oil from the 44oz of refrigerant. If it says 44oz of refrigerant, that is how much you put in.

The 85% idea is what I've read on all the DIY kits. If its safe at 44oz ill do it.

What's your thought on the orifice tube?

Changing the orifice tube was recommended to me. It is located in the tubing. Do a forum search for orifice tube, I know there is a picture on here somewhere.
