Just had the car (95 Caprice) in a shop to confirm what I pretty much thought. I've noticed for a while now little drips of yellow colored oil on the bottom of the Compressor. then the other day after backing out that there was a lot of Clear colored oil on the floor and thought it may be from the compressor. The shop confirmed it's leaking around the seal near the clutch and it's time to replace. The odd thing is the air still works and blows ICE Cold. But the wife did say it stopped once and then started working again....weird.

They wanted about $700 for all the parts and labor to do this all including a new orfice tube, Dryer, and the manifold hose that goes on the back. when you add up all the parts and their labor, that seems fair, but I know I can most likely do it for 1/2 of that and then just pay them to evac the system and charge it for about $100. not really interested in picking up gauges and all and doing the recharge myself so will just job that out. He did say it wont hurt to drive it as the compressor shouldn't lock up or anything, it just wont work anymore.

So if I order the parts myself, what/who would you guys recommend?? I found these guys recommended in the Sticky and spoke with Tim there....

COMP HD6 PV6 5in 12V 10:00 VIII. W/O SWITCH

He was very helpful and recommended everything I needed and has a kit (not listed on the site) he can sell me which will include Compressor, Dryer, Otube, Oring kit and oil for $223. This is a China Compressor and he has the AC Delco for another $80 but to his credit really said there is not much difference in either or that "they both seem to have the same failure rates" and just recommended the aftermarket unit. He also feels most failures are from users not flushing out the junk. Years ago I may have opted for the more expensive Delco part, but recently it seems AC delco is not what it used to be when it comes to replacement parts. What's your thought on this or do you all have any other recommendations? Any other online vendors I should consider to save some cash? Any other things to consider replacing and while doing this myself??

I will check the orfice tube for debris but suspect it's fine and just the compressor seal leaked. So it may not really need to be flushed out. Tim said if it does, he was not familiar with Kooler Klean product but said the AUTOACFORUM.COM had good info on the proper method to flush out the system. The shop that checked the system did also recommend that I replace the manifold hose set that attaches to the back of the Compressor. Do you also agree with that, his cost on that was only $48 so it seems like a no brainer to do this as well. Will also take apart all the connections and replace ALL the ORings in the system.

Appreciate ANY and ALL feedback you guys may offer as I need to get these ordered in a few days and get my AC back up to snuff. Thx.

Having just replaced everything on mine I'd go for the kit he recommended. I went a similar route via Autozone.
It was $226.36 shipped to my door, but they also had a deal that got me a $50 gift card as well.
Beauty is w/ AZ lifetime warranty & local.
I went with UAC hose assembly $38, and UAC condenser $83.

Just about every new compressor is made in China these days.
The new Delphi I bought was $169 made in China and it was bad right out box, returned.
The new ACDelco hoses and condenser I bought for way more were cheaply made and returned.

If you choose to flush it is VERY important to make sure you get everything out. DIY flush kits seldom work well. If the orifice tube is clean I'd pull the condenser and have an AC shop flush it. Probably cheaper than buying flush supplies anyway.
If the orifice tube has any metal shavings just replace the condenser. Almost impossible to get metal out of them.

Thanks bwag - didn't even give AZ and the lifetime warranty a thought and surprised that one if offered. But after checking them out, I may just go that route too....strictly for the lifetime warranty. This deal is $261 plus they have a $30 rebate along with a $20 credit I have. I can apply those savings toward the new AC Manifold hose. There was also a $10 inline filter kit I would most likely throw on there for extra protection.

I'm going to still shop around some, but this may be my best deal along with the warranty. Honestly surprised that they give this a LT warranty as the individual compressors only come with 2 yr warranties.

I was doing a little research last night and I'm considering buying or even doing the loan a tool thing and evacing and charging the system myself. It still seems to be a little bit of a mystery to me and there is the fear factor of screwing up vs the low cost of just paying someone else to do that part for me.

Found this thread which has lots of good info along with some vids up on YouTube which explain the process better....

http://www.impalassforum.com/vBulletin/53-heating-cooling-hvac/243024-want-replace-my-ac-compressor.html

....but if I can find a shop that will do this for about $100 then I may just go that route again.

I am going to rebuild the compressor myself on my Tahoe. There's a few youtube videos on it and you save a ton if nothing major is messed up.

Now I see this! :smile2: Oh well, I was already committed to a new Compressor anyway figuring a 20 YO unit was in need of replacing. I'll have to check out those videos anyway and maybe hold onto my old Compressor just in case.

I did manage a pretty good deal from AZ "Ship to home". got the Compressor kit and a GM Manifold hose for $300 after a 20% discount which saved me over $75 on everything. also found a shop through a buddy at work that will evac and charge the system for only $50 once I get it all installed.

How much oil to add and where?

As a follow up on this thread and before I install a new dryer, compressor, manifold hose and orfice tube....How much oil needs to be added to the compressor and/or other parts??

I've got a few suggestions and did some research on the web, also checked my service manual but can't seem to find specifics. Most info I've found has said to just drain out the old compressor, measure the amount of oil and add this amount to the new compressor. Problem is, most if not all oil has leaked out of the system already so I don't have that as a reference.

Compressor - Some people I've checked with have said to put 4 oz in and also heard anywhere from 2 - 8 oz, so just not sure which is correct. Also read somewhere that you don't want to add too much oil or it will be inefficient and too little is also not good. The guy charging the system said that the freon they use will also have oil in it so how does this get factored in to what ever other oil may be in the system? At this point I don't see a need to flush the system since it was still working and I have not used it since losing the oil. If I happen to find junk in the orfice tube I will then flush the other parts....but if all looks good will leave it alone.

Dryer/receiver - Some have also said to put an oz or 2 into the receiver/dryer as well, yet some have told me not to. If so, is there a specific port that the oil should be put in or dos it not matter??

Appreciate your thoughts on this as I hope to get everything installed in the next week or 2. So how much oil should go into a fresh compressor one system that has already lost a lot of oil and should I also put oil in the new dryer?? Sorry for all the questions but this should pretty much cover it and I can get starting on this repair. Thanks all

Manual lists below for adding oil when replacing.
Evaporator = 3
Condenser = 1
hoses = 1
Acummulator/reciever drier = 3.5
Compressor minimum is 1 oz. but they say to match existing level if more than 1 oz.
Problem is they don't list a max spec.
If you have a big leak, oil goes bye bye, so ???

So after reading the manual, and based on my past experience with A/C work.
I made an educated guess that I felt comfortable with.
When I did mine compressor got 4oz., receiver drier got 3.5oz., condenser got 1oz., hose assembly got 1oz.

I would much rather have a little too much oil vs. not enough.
#1 killer of compressors is lack of lubrication. Either brought on by big leak, or incorrect servicing.

Kinda how I'm leaning at this point too. Was also thinking more about this last night AND may just go ahead and replace the Evaporator too while the systems down. No problems with it other than its original.

The only concern I have is the added cost, not to mention possible aftermarket quality compared to original part. Also, not looking forward to accessing the heater core area again, but it may be worth the effort to replace this part....then again, I may talk myself out of it. >:).

Bob,
Why would consider replacing the evaporator core? Unless the system has a leak in that area, I wouldn't worry about it.

As I wrote in a thread I detailed replacing components and charging the A/C system, I only put oil in the compressor, and receiver/dryer. I didn't put any in the lines. You don't really have to worry about putting too much in one area or another, since it's a sealed system it all gets together once pressurized.

What I would suggest is replacing all the O-rings since your doing the work. Either you or your A/C guy draw a vacuum for at least an hour (This is the only way to remove moisture in the system). After an hour turn off the vacuum pump, and walk away for a half hour. If the system is holding steady @ -30Lbs, then you're good to go with a charge.

Let me know if you need anything else.

I wouldn't replace evaporator.

Only reason(s) I replaced my condenser was because it was bent, and lifetime warranty on compressor it required replacement.

Thanks for the input guys. The only reason I was considering replacing it was due to it being original. You know, put all the time in to replace other parts, get the system charged and then get a leak later on that part. Then kick yourself in the ass for not doing it. But maybe I'll just hold off on it as I wasn't looking forward to opening up the air box again anyway. Ac has always worked great and blew ice cold.
