whats involved in this process and how much does it cost about to get it done?
the only reason I wanna know is I'm moving to phoenix in october to go to UTI and I don't have a AC in my rex but a friend of mine has his old compresser and condensor and all the lines and is gonna give it to me for 25.00.

do you have to just buy a new compressor or was that with the old one? can you still get the r12 recharged anywhere and if so about how much does that cost?

 

You need to buy a new drier bottle (roughly 35 bucks) and clean the hell out of the system. don't use water in the piping! I recommend compressed air. The conversion kit for R134a is cheap. You can use the regular compressor, but make sure it's in tip-top condition, My old compressor was sitting around for 4 years, and when I put it back on and did the conversion, it blew a leak after 5 months. I'm waiting on a new one, but the conversion works pretty well. You can do it yourself in an afternoon.

 

cool thanks for the info. where can I get the conversion kit? just any autoparts store?

 

autozone, pepboys they should all sell the conversion kit..$35- did it on my 92 prelude. Works fine so far one month into it. just follow the steps that comes with the kit

 

couple of hints. while you're doing it, it's probably a good time to take the evaporater box down. it's behind your glove box. clean it out, it's probably got old leaves and junk in it, and give it a good spray with lysol disinfectant so your air doesnt smell moldy. if you have an air compressor, see about blowing out all the esther oil out of it too. The R134a uses a different oil, and you'll find a lot of it in the evaporator.

 

Well, you can get away with not changing the drier or anything. But once you put all of the lines and compressor on your car, you need to use a AC machine and vacuum the system down and let it stay under vacuum for a while. This sucks out all of the moisture out. I work at a auto repair shop and when we convert cars to R134 we just change the AC fittings and vacuum the system and then recharge it. Just don't fill the system up to the R12 level. If a car holds say 2.3 or so lbs of R12, then we put roughly 1.5lbs of R134 and double check the pressures on the AC machine.

 

the conversion is very easy to do. the most important thing to do. is NOT to mix r12 oil with r134a oil if you do it will contaminate the system and you will have leaks down the road. the 2 oils are ester and pag

 

well hey looks like I'm getting a air conditioner. thanks guys.
