How much freon and ester oil does my van a/c system use?
Hello, I have a 96 Plymouth Voyager with a 3.3L engine. I found the little sticker that lists the amount of R-134a, but it list it as 3lbs. not in oz. like is on all the cans. I know there's 16oz in a lb, but 48oz of refrigerant seems a bit much. I seem to recall being told that my system takes 24oz. but I have not been able to verify this.
Also, since I am filling my system completely (I had to replace my compressor) and I salvaged one from a junkyard, how much ester oil should I put in when I refill the system?
I don't believe it has rear A/C. There are no vents in the back. There is another number on the sticker that I believe says 2.3 lbs, which I think works out to 36oz. All I need to know now is the amount of ester oil to add.

If it takes 3 lbs. you must have a rear AC system. Just wait until you fill it and it all leaks out! Vehicles with rear AC units tend to all have leaks develop in the AC lines running to the rear evaporator. It's going to be expensive! Probably cost more than the vehicle is worth! Better make sure the front upper strut mounts are not rusted away before investing any money in that vehicle!

If you have rear A/C, then 3 lbs is the correct refrigerant charge. You're got two evaporators and very long lines to fill with a rear unit

You should take it to an auto A/C mechanic and quit trying to be the Wizard of Allschitz, otherwise, you will pay for more parts.
