Changing out the compressor

My ac has been out of service for about 1 year now so i took it in and they said my compressor is leaking. I think I've found a pretty good deal on a compressor kit on ebay. http://cgi.ebay.com/ebaymotors/_Car-Truck-Parts-Accessories__HT6-COMPRESSOR-KIT-Pickup-Suburban-Tahoe-Yukon-S10-S15_W0QQitemZ280246835875QQadnZCarQ20Q26Q20TruckQ2 0PartsQ20Q26Q20AccessoriesQQadiZ2865QQcmdZViewItem ?hash=item280246835875&_trksid=p3756.m14.l1318 What do you guys think? Also, its still over at the shop, so should I have them, I guess you'd call it, evacuate the system before I work on it, or am i gonna be alright? Any other tips on doing this? I assume my haynes or chiltons manual is just gonna tell me to take it to a trained professional, but they want to charge me like a grand to fix it.

If you don't have a way to evacuate the system yourself you'll have to have the shop do it, but the new compressor and drier needs to be installed first. Also, you would need a good set of gauges to charge the system. As for the deal on ebay, it seems pretty good although it doesn't say what brand and there's nothing worse than having a new compressor go bad after you install it cause you have to do it all over again.

I just read another post which pretty much cleared everything up. But just to make sure: I'm gonna remove the compressor, measure out the oil that comes out of it, and then put that same amount into the new, empty compressor. Replace the accumulator and orifice tube and then probably end up just having the shop refill it the correct way. Now, when they refill it, after I would assume emptying the whole system, does the system lose any of the oil?

Most new a/c compressors are remans and are junk.One from 4 seasons is one that is junk and will not warranty them if they fail.Used ones from your nearest auto wrecking yard hold up better than new ones.

No, there shouldn't be any oil loss from evacuating the system. Really all they're doing is pulling a vacuum on it for probably 30 minutes to an hour to remove moisture. Also, the shop manual should tell you how much oil to replace when you change the accumulator. Also, be sure to use the right oil because mixing types can actually eat a A/C system up.

I heard the OEM ones fail pretty regularly due to a design flaw and the new ones actually are "keyed" or something and hold up better. I found a company that sells both remaufactured ones and new ones. Do you still suggest one from the junk yard, or a new one?

I have used ebay compressor's in all my cars. No complaints

The junkyard ones are better and hold up longer.

since you have only a few dollars to gamble on my suggestion why not recharge the a/c with r134 and install a can of refrigerent with about 6oz. of pag 150 oil, which if it is a GM vehicle should be correct so check first and give it a go ....most it will cost 35.oo...why not...if it's leaking at shaft seal this may do it as the oil helps stop leaks there...
