So now I got all these parts...

Chevelle_nut on Thu August 28, 2008 9:13 PM User is offline

Year: 1999
Make: Chevy
Model: Cavalier
Engine Size: 2.2l
Refrigerant Type: 134A
Country of Origin: United States

So I'm ready to put a seal kit in the V5. Without knowing which shaft size I ordered the 2 different sets. Near as I can tell the shaft is the standard 15mm. (my verniers won't reach that far into the hole). So I open the package and man there's alot of stuff in there. Parts I didn't notice coming out when I pulled it apart. The first bit of confusion is the 2 piece seal ? The main part (one bonded to the metal casing) I get, the little flat seal - I dunno. The orings -no prob -match it up with the one that came out -good to go. Felt wiper ? Where does that go ? I didn't have one to start - do i need it? Also I ordered a bottle of DEC 150, should I distribute that amongst the condensor/accum/compressor ? Or do I just pour it in the plug on the compressor body, and then turn the compressor by hand before vacuum and recharge.

Oil, personally I would do 80 percent in the compressor spin by hand and the rest in the accumulator.

Shaft seal, check out Chick's very helpful post ion this subject.

Thank you for the oil up info. I am using the guide as the inspiration for this undertaking. Plus after my first few go-rounds I have had some major successes using this forum. I found another thread in Procedures, Tips and FAQ's last night that showed the felt washer on an A-6, so I'm under the impression I don't need either (thick or thin) of them. The major question is in the 21-34569 seal kit, the parts diagram shows a MC-556DN - it has 2 pieces, am I supposed to put both on the shaft and in what order ?

Thanks again,

Scott

I do those seal changes in my sleep- but I don't use a kit- so I am not up on the part numbers you speak of- I could recognize all the parts you are trying to use- if I was familiar with the kit- or saw a photo of what it contains. Give me a link and I can help you out. I do know the felt washer was used in HT-6 applications- if your OEM doesn't have it- forget it- I never use one on any applications.

I'd be wary of body o-ring leaks on that '99 V-5 compressor- anymore, I change those along with the shaft seals- Had a two comebacks last year that were both body o-ring leakers- both were '99 model V-5s.. so I anticipate those failure and just go ahead and replace them- it is more work- taking the compressor apart, but in the end is worth it.

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......

Kit looks good- the little rubber element next to the shaft seal is used on R-4 truck applications applications as a dust shield- (you won't see it anywhere else). The felt washers are there to replace any you remove- and you match the new o-ring to the old one you take out-

The title does not include the R-4 - although it is the same physical dimensions, and it works just fine-- I suppose it is not titled that way because double lip seals came out after R-4 left the OEM market- and are only service compressors now. The rest of the parts are obvious.

O.K. so all the parts are in, new oil is added. It's on the suck pump now - keeping fingers crossed.

Yes! another successful venture !! Thank you Tim, Chick and GMtech ! The car drew a nice vacuum (26 - all my sucker will do but I stayed on it for 2 1/2 hours ) and it held it for 1/2 hour. Juiced it up and now:

87 ambient
High side 220 @ 2000 rpm
Low side 30
Vent temp on recirc ,3/4 fan, drivers window open 1" a frosty 42 !!!
Took it out for a road test and it dipped into the 30's

I hope that seal holds !! WoohOO !

Thank you again Tim for the great site, advice and best parts !

Now it's time for a frosty beer for dad, cheers

Just a bump to thank you guys again for a wonderful forum and sage advice. The Cavalier is doing well, showing 40 at the vents all the time ! Tim that seal kit is a thing of beauty. I was kind of having a nostalgia flashback tonight when I diagnosed the wifes Voyager having a bad Blower motor. I don't remember taking it out by itself, only the total horror from pulling the whole unit out to change the evaporator. I could not imagine trying that one without the advice and guidance from all of you. ( and no Chick - I never did find that piece of fish line ). Well 8 or 9 screws later and the motor assy. is in my hand. Phew an easy one finally !

Keep up the good work Men!

Forever grateful,

Chevelle_Nut
