1988 A/C Refilling after system evacuation

[Fizz88]

Recently on my 88 turbo coupe, the A/C accumulator was replaced. Had a shop evac all the old stuff in the system and they removed it a bit ago. Got the part after and I put it on today, used one of those things you get at auto part stores to refill it, believe the name is "A/C Pro". Unfortunately I did not research thoroughly and I missed steps.. apparently Ester oil should of been added before hand, the recharge bottle I got has PAG oil in it. Does the system need to be evacuated again? It was already evacuated when the shop removed the accumulator.

Are we dealing with r12 or 134a, would not make a difference, just wondering....Was your a/c working fine before the accumulator was changed ? I ask because if all your other parts in the system was good, I'd vac pump it, (that not only gets out moisture and other crap but will also give you an ideal on what kind of leaks the system has by how long it can hold that vac.), now ya kinda lost me on the end, If the system was working fine before the accu. change, suck the system out and then add your freon up to around 40# low side, I've rebuilt mine on my '95 a couple times, I stay clear of any added sealants(glue) in my freon, I don't have any problems with dye in my freon, that's the way I've always done my system.....IF your system is in decent working condition, try to stay clear of just adding oil by itself................

It wasn't working properly before hand, hence replacing the accumulator. Also dealing with r12 to r134 since r12 isn't sold anymore. The ac pro has sealants in there including a small amount of PAG oil. Also heard the orifice tube will need replacing, is this true? I didn't find any metal debris so I didn't think it would. Though I Could be wrong.
