Leaky Compressor?

Briandl79 on Sun June 06, 2010 10:56 PM User is offline

Year: 1997
Make: Chevy
Model: Cavalier
Engine Size: 2.2
Refrigerant Type: R134A
Country of Origin: United States

So I'm helping a relative out with his A/C. It's a daily driver but sort of a beater, but it gets good mileage so he'd like to get the A/C working so he can use it for trips nearby out of town.

I checked the system and it was totally empty. I went ahead and pulled a vacuum and after about an hour it went from 30HG to about 19HG. So I went ahead and bought a 12oz can of R134A with UV dye. I went ahead and put the 12oz can in and it got pretty cold, down to about 57 standing still (not bad for only half the total charge amount). I ran it for ten minutes and a few hours later when it was dark I got out my glasses and UV light and finally found the leak. The leak appears to be on the compressor at the location I've indicated.

So I checked out local parts stores and the cheapest compressor I could find was a reman at 185.00 and a new one of the same brand for about 225.00.

So, here is my question: Can I fix this seal myself? Is it hard to get to the seal, find a replacement, and change it?

TIA!

EDIT: Just wanted to add that O'Reilly's has a bunch of different compressor seals: Compressor gaskets, A/C shaft seal kits, etc.

That would be a classic "belly leaker" and yes it can be resealed- I would also put in a new shaft seal at the same time. You will need some specific tools- and for doing just one job, it may not be worth it-- only you can decide that.

The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......

Is it possible that AutoZone rents out the tools I'd need?

Those are a couple of the tools you would need, but the cost of all the tools for a one time job just isn't worth it in my opinion.. Check out V5 reman compressor at ackits.com you know it will be done righht, and a "quality" reman..not a repaint.. just my opinion..

Yup classic problem on the V5 but very easy to repair with the tools,either get tools and do the repair(search v5)or do as chick stated

It would be nice to have some idea of what all is involved, including tools and seals. I'd rather have an idea myself so I can decide, rather than just being told to get a reman. I did search around but I haven't found any specific instructions on repairing the belly leak on the V5.

Is this what you want? True, it is a V-7, but a V-5 uses the same tools...

I am doing something similar on my 1998 GM V5 Compressor. See this thread null

For the V5 compressor, I spent (so far) $103 (plus shipping) from ackits...these were my parts and prices:
SHAFT SEAL KIT V5 HR6 HT6 DOUBLE LIP SEAL (ackits part # 21-34659 ) $9.68
GM Ceramic Seal Set Removal - Installer (ackits part 90486) $20.88
GM Seal Protector (ackits part # 90484) $5.12
P125-8TSI - DEC PAG - Blue (8 Ounce Bottle) $8.94
Nylog (Blue) Gasket Thread Sealant (ackits part # RT201B) - $9.49
Accumulator - Drier (ackits part # 37-23404) - Price: $19.42
1989-2005 General Motors System O-ring Kit (ackits # CP3010) $11.22
2005 & Prior - GM Sealing Washer Assortment (ackits # CP3016) $10.51
White Orifice Tube (ackits part # 31-50001 ) $1.27
GM Noise Buster V5 - Gasket Kit (ackits # 21-24683) $7.43


I am doing the V5 shaft seal..hopefully, the case/belly orings...I am also doing the Accumulator...possibly the orifice tube...


Just for the SHAFT SEAL KIT, Seal Removal/Installer, and Seal Protector, you are likely looking at around $40?...
then you need the belly/case orings...if you get the kit around $10??...

You would likely also need...
- Compressor plate holding tool (approx $15-20?)
- Clutch puller/installer tool (approx $25-30?)
- good pair of snap ring pliers ($25?)
** these tools can often be borrowed/rented from local auto stores, like autozone, advance...


You can see that it can get pricey...

Thanks, that really gives me a great idea of what all is involved.
