What is involved in converting the AC from R12 to R13a. Is this something I can do or should I leave this to the pro'*? Expensive to do? 92 Bonneville SE L series

A controversial subject!

You will need to capture the remaining R12, repair leaks, put a vacuum on the system, add oil, and carefully add refrigerant and oil while monitoring high and low side pressures. A vent thermometer and a large external fan for the condensor also are necessary. Many people recommend changing the accumulator/drier and also the existing o-rings.

Unless you have done A/C work before, I would leave it to a good A/C shop. That'* because damages from doing it wrong are much costlier than the retrofit.

I don't think it'* that expensive, $200? Depends on what you think is expensive I guess.
Does your air work now with the R-12? If it does, just keep using it til it breaks.

That whole R-12 freon thing is one of the biggest crocks foisted on humanity. It ranks right up there with the Global Warming hysteria.

Maybe we could buy you a one-way ticket to Antarctica to work on your tan, right under the hole in the ozone layer.

i got every-ting you needs. Bottle says "Replaces R-12, 134a,
NO retrofiting required
Runs colder than R12
Equivalent to 510 grams
My car calls for 2.2 pounds which is 997 grams so I need about two bottles, it might be a good idea though to oil your system first (same type of can)
Each can costs 15bux Canadian, the hose thingy was 85 bux

Can putting the r-134a in wrong cause the compressor to go bad? Because i recharged my system, and converted it, and i lasted a week, and it started working, and then would stop. finally it just stopped. I threw another can in, and it was cold and working. I shut off the car, took a shower, and then it was warm again. I got power going to the compressor, but it isnt kickin on. how come it kicked on when i threw another can in? and then it quit all of a sudden, after it was off for like 20 mins.

if it is the compressor, where can i find one on the internet, reasonably priced.

thanks,

Rob

What are the high and low side pressures on your car, along with outside temperature? You have to take them with a big fan in front of the condenser, 2000 rpm, A/C on max.

You may have overcharged the system.

can over charging wreck the compressor? or cause it not to kick on?

Rob

If you overcharge it, then the compressor may try to pump liquid instead of gas, and that will destroy it. I'm not so sure that you have a compressor problem though... Best way to find out is to get some pressures.

my dads friend had this gauge, and his read 60 PSI for his dodge ram, and mine read 95 PSI? am i overcharged?

I want A/C!!
