I had to remove my a/c unit to pull my motor. My question is since I removed the line is it just simply fill it back up and go or is there something else I need to do?

um it has to be recharged properly using the correct type of refrigerant and more importantly oil. if you use the wrong type or overfill, you can cause serious damage.

I understand it needs to be properly recharged, but what does that mean? Fill it till it says its at a safe level on the refrigerant gauge supplied with the can of refrigerant, or some other way? And oil,is that the little cylinder next to the fans? Can I do this, better yet can i get the oil to fill it?

Located here right?

Did you let it out fast? If you did there is a good chance you let alot of oil out. The only safe way to put the proper amount of oil in is to flush the system out and refill it with the proper amount of oil. TOO MUCH OIL IS JUST AS BAD, OR WORSE THAN NOT ENOUGH SOOOOO
, Don't just pour some oil in a think its ok. The amount of oil is a calulated factor. The refrigerant "carries" the oil through the system. To much and it can't carry it all. To little and it is just like running your engine with not enough oil... Aside from that you need a deep vacuum (30" of Hg) on the system for atleast 30 minutes or so to get extra atmosphere out and to vacuum moisture out. Moisture is death to an
a/c system. It mixes with refrigerant to make acid. In short not discounting your abilities at all, but if you don't have a firm grasp on air conditioning theory do not attempt it, fixing any mess ups is not cheap at all. Trust me (been a certified a/c tech for over 10 years), by far the most expensive a/c repairs I have been involved with have been the ones that someone who thought they knew what they were doing and didn't it......

i do not want to sound like im telling you to give up, but from your posts its clear you do not have enough of an understanding of the system or proper equipment to diy (i wouldnt do it either, and no you cant just buy a can at the auto store and spray it in). the dealer and shops have big machines that do this stuff and they know how to use em. a/c is no simple thing to work on and ive even seen auto repair shops botch things up horribly because they were cutting corners and didnt specialize in that type of work but took the job anyway. the only thing i would do when i worked at an auto parts store would be to recharge really old a/c systems that had slow leaks and had lost all the charge so the compressor wasnt even running. i never messed it up, but i always made sure they knew that letting me do it for them could cause a disaster and they were fine with it lol. i mean, it wasnt working in the first place, so not much to lose i guess. to them having cold a/c for a month or two is worth the $20 can. there are tons of parts you will have to replace if you mess up.

If you DIY or not make sure the connections you opened are clean and capped or covered with plastic and secured so no particles or moisture can get in. I hope you cleaned the area before disassembly? The "almost" DIY method would be to put it back with all new o-rings (oiled w/esther oil, could never find ND-oil) all torqued to spec and take it to someone who can pull a vacuum and add refrigerant while also following johndeer's advise.
Things that could go wrong besides oil, are leaking at connections and foreign matter in system ***-u-me-ing everything else was good.
happy trails

Don't use esther though. It does not mix with r134. Esther is for r12. Use pag.

I just disconnected the line on top of the motor. let the pressure out slowly. Dont see why i just cant refill it with r134 and be good!! I am confused as to how i need oil now!!

 
Rep Power: 199

The oil is carried in the refrigerant. You can't let refrigerant out without loosing oil period. The bigger picture though is that it needs vacuumed down. See above post. Moisture is death to an a/c system. If you let it out very slowly, I am talking like took atleast an hour to let out slow, you didn't loose alot of oil, but the moisture has to come out....

If you have no leaks I'd pay to have it done professionally. If you DIY and mess up it would be an expensive fix.

If you choose to DIY here's a decent guide: http://honda-tech.com/showthread.php?t=1665946

It's not as simple as plugging in a can of r134a and filling it up, you need to purge the air/moisture out of the system too.

pay $100 or less for a shop to recharge it properly, or pay them $500+ when you mess up and have to bring it in anyways. you choose.

Regardless least of my worries till i even get the fricking car back together.

And the dealer will get the apprentice to stuff in a can of refrigerant.. just like you were going to do.
Only difference and it may be an important one is IF it screws up after.
The dealer should stand behind it ..Or they might find a way to weasel out of it ie: it was just a reharge.. none of our doing.. must have been prebroken

Note that AC is THE biggest profit area in a shop. Lotsa nonsense mumbo jumbo is bandied about . No one wants the serfs learning how to do their own.. do they :-)
PS: a Salvaged Refrigerator Compressor is darn near as good at pulling a Vacuum as most Any 'commercial' shop gizmo.
