A/c

I have an 89 estate wagon which is the same thing as a caprice wagon. Since nobody in the buick forum knew i came here. I am thinking about tring a A/C recharge kit they sell now and if anybody here has tried them. Is there anything i should watch out for? I dont like messing with pressurized lines so this is my first time working on an A/C system. Any help would be great.

your A/C system uses R-12 (unless it was converted) and you can't buy R-12 anymore, only R-134 and the 2 are not compatable.

Yes they are, I did the R134a retrofit conversion on my 84 caprice last summer, and it still works great. I had my doubts since the system had been out of operation for 6 years at the time, but it worked like a charm. Just be sure to not to put 2 much stop leak into it (no more than 2 cans) and get at least 6 ounces of lubricant into it. Also, make sure the freon you put in is the high mileage stuff. Otherwise, you should be good to go. Oh, and you compresor probably wont come on and stay on until the 3rd can.

How do i do the retro fit?

You need to buy the kit. All you need to do to is change the service ports on your A/C system (the nozzles that look like oversized tire valves) which come in the kit. They just screw on over your old service ports. The you have to make sure all of the R-12 is out of your system. To do this you legally need to take it to a licensed professional to have your system flushed (many shops do it for free because R-12 is so expensive, that anything they recover is like money in thier pocket) or if you dont feel like doing that, just press in the valve on one of the service ports and let whatever is left out, but dont get caught ($10,000.00 fine, and possible year in jail). Anyway however you do it is up to you, after you've emptied you system, and changes the service ports, turn on you car, and turn your A/C to max. Then go under the hood, and use thehose the kit came with and hook one end up to the can, and the other end up to the low pressure side service port usually on the dryer (big aluminum cylinder thing near your firewall). Slowly open up the valve on the can, and let the freon flow out. It will take 3-4 cans of it before its fully charged, and the compressor should start kicking on after the 1st can.
