1993 jeep grand cherokee A/C Accumulator
Hey everyone, I'm currently in the process of replacing my accumulator on my GCL. Reading the manual and it says to fill it back up with that same amount of oil that came out of the old one. when i drained the oil, the only thing i got was bright green fluid. this doesn't look anything like the refrigerant oil that i bought to refill it with. I did use a UV leak detect, and I believe this is what i'm looking at since i've found it on all the connecting points (for the condensor, and pump also). I want to know how much oil to put back into the system. A speedy reply would be awesome, since this is a one day A/C system change (compressor, condensor, accumulator, and fixed orfic tube). I need to have this at the shop tomorrow to get it evacuated, recharged, and leak tested. Thanks guys.

If you are going to take it to the shop for evacutes and recharge, don't put any oil in it because it'll ended up sucking back out during vacuum the system, they'll be able to tell how much oil they've got out and I'd just let the shop know that I do need additional 1oz + the amount of oil recover during evacutes add to the system.
The bright green color is comes from the dye tracer that you put it in.

i replaced the compressor, condensor, accumulator, and fixed orfice tube. when I replaced the accumulator, your supposed to removed the schrader valve under the accumulator switch, drain the oil out, then add the same amount +1 oz. Well, when I drained the oil out of the accumulator, it was all the color of the dye, and only got about 2 oz. out of it. I didn't put any oil back in the accumulator yet. I want to know how much to put in before I take it to get charged. Or should I just leave it empty and let the shop add whatever needs to be added?
I won't be running the A/C til it gets evacuated and charged. The fuse has been pulled so the system won't operate at all til I get to the shop.

If you got 2oz. out put 2oz. back in. The only reason it's green is because a tracer dye was added at some point...the stuff you are actually looking at is the oil (just changed to a green color from the tracer dye). I personally would still add 2oz. because even when you evacuate an AC system you don't get ALL the oil out of the system...there's still a little left throughout the system.

Thanks Davzak, you're the heat. I found a place that will evacuate and recharge for 30 dollars, plus whatever it costs for the refrigerant. they charge 10.99 a pound for refrigerant. I'm extremely happy I changed all the parts myself, and found this shop. Pepboys qouted me $1300 to do all the work, I changed that to about $915 by using my skills.
Now, if you'll excuse me I've got babes to chat with and cage matches to train for. peace out.

I guess you already replaced all the components right!
I was going to suggest using a product called "NyLog" on all the o-rings and other fittings.
This stuff is great......it's like a tacky, gooey liquid in a squeeze bottle that's made specifically for MVAC that you apply during assembly. It never hardens.....I've undone A/C fittings after more than five years and the NyLog is still as tacky and gooey and the day I used it. I also use it on the service port caps after charging a system for a little extra security against leaks at the service ports.
If you do use NyLog on an A/C fitting, and there is no mechanical problem with the fitting itself...... It will NOT leak, EVER!

thanks for the info on NYLOG. I'm getting the system evacuated and charged tomorrow. If I find any leaks, i'll be sure to use this product. It sounds pretty impressive, and I like my A/C to work, even though it hasn't worked in 3 years. That's why i've had to change so many parts, just want to make sure it's all fixed and won't run into another problem next year.

You left out one of an important part in your jeep which 85% of the leak is coming from, "Evaporator Coil". It's known to be one of the weakest part that causing a/c leaks in Dodge/Chrysler/Jeep.

Evaporator Coil
Where is the evaporator coil located? and is it hard to get to? My luck it will be. I don't really want to pull apart the dashboard to get to it. But since late last summer when I replaced all these parts, it has leaked out all the refigerant. Granted it's been winter and I haven't had to use the A/C, but it's starting to warm up again and I might as well change it before I service it again.

Sorry son but yes the evaporator is behind the dash/ glove box.Not to hard to do , if you have the time. I would try to charge it first and see if it needs replacing.Since you have dye in the system check the drain plug for the evaporator(pass side under the hood down towards floor) if it has green residue its the evap.
oil does not get sucked out when in a vacum only when you recover freon is when you loose oil.
