1976 Buick Electra Compressor replacement

cmeseadoin on Thu May 01, 2008 10:46 AM User is offline

Year: 1976
Make: Buick
Model: Electra 225 Limited
Engine Size: 7.5L
Refrigerant Type: R134A

Greetings,

I am looking for an A6 compressor for my 1976 Buick Electra 225 Limited and I ran across the reman'd A6 on here for $133.xx. I wanted to make sure that this was the entire compressor with clutch and single groove clutch pulley as the description was not 100% even though the picture was of the entire thing. My problem is that I currently have an A6 on the car with a leaking front shaft seal that is leaking oil and refrigerant over time. There is also a leak around the thermal switch one prong port on the back of the compressor where the liquid lines attach. I have dyed it up and I can see oil leaking from the front shaft and all between the clutch plates as well as where this circular switch fits into the port and has a clip around it on the back. The line connections are not leaking. I do not have the tools to install a new shaft seal and am not sure what to do about the thermal switch leaking either. Perhaps the big o-ring on that switch that slides in can be replaced? I was curious if this reman'd unit came with a new switch on the back or am I going to have to pop mine out and put it in this new compressor and most likely have yet another leak? Also, if I replace the compressor on the car, what would be a good rule of thumb with oil replacement...amount and type? I think I used something like BAV before? Any information would be great! Thank you!

Oil amount 10 or 11 ounces, it has a sump, the switch doesn't come with a reman compressor, but when you switch them over, you would use a new O ring. If a "new" compressor is available from Ackits, I would go for the extra money and use the new one, just my personal opinion though.. Clutch comes with the compressor, but to be sure and have any questions about the compressor answered, you can e-mail the guys at Ackits.com and they are very friendly people who will answer all your concerns.
I would recommend the BVA auto 100 oil if using R134a. Thats all I use and it works great.. If you use a PAG oil, use their double end capped 150 viscosity..Hope this helps..

Thank you for the reply. What you have said makes sense to me. I recall now, I used the BAV auto 100 before and that amount of oil is now ringing a bell. It's been several years for me.

I know you recommended the NEW compressor vs. the reman'd unit but I am looking at price, $400 vs. $133. I know that often in life, you do get what you pay for, but I was wondering what the main differences were. I purchased a reman'd unit local in town and installed it, set it up correctly and the front shaft seal is leaking and blowing oil and refrigerant. I was curious, if perhaps, this was because the reman'd unit I bought locally (probably some inferior quality product for cheap $) was just plain garbage, or could running R134A along with an A6 be causing such high pressures that it is making the compressor leak at all the weak points such as the thermal switch on the back and the shaft seal? Do you think that if I stick a new $400.00 compressor in there I am going to blow the shaft seal again? I don't want to continue to spend good money on compressors and be dealing with faulty leaks all the time. And ideas on this? I am sure it is very subjective, but just looking for some advice. Thank you again!!

Chris
