R134A refrigerant ?

[Accord07]

Has anyone tried this in their CB ?
I cant seem to find R12 anywhere around here now.

It is possible to do a R134 conversion without swapping out any components (except for the R12 of course).

[whitejdmcb7]

its expensive so beware they make a conversion kit for it

Nope. For one, 134a uses physically different fittings on the pipe and hoses. Two, the oil that exists in the system is different. Different gases, so the oil won't go to aerosol correctly. Three, you have to change the compressor (the part that the belt drives on the engine).

R12 has become extremely expensive (price/lbs) because it eats the ozone layer.

Your options are to a)pay more for R12 every time you get a charge, or b)spend $50 for the retrofit kit from honda and hope you can find a 134a compressor in the junkyard for cheap (or pay $500 for one from honda). You would be able to use a Prelude one if you changed pulleys. Not sure if a newer Accord one would work or not. You might also look for a CB7 that has already been converted.

If your system works well and doesn't leak, I'd just stay with R12. You'll pay more, but it's less of a hassle.

One other option is to learn how to do AC stuff yourself. In CA you have to have a license to buy Freon and all the scales and gauges and stuff. My dad has it, so we just do our own AC repairs. Lots cheaper, and it really isn't that hard. Places charge $100 for what is really a 10 minute job (assuming everything is ok, no leaks).

you'd have to get a new dryer and possibly condensor, b/c it'll be caked w/ that R12 refrig.

I just got my R12 recharged for like 60 bucks, I needed a can of it, which cost about 40 and then labor was 20.

But it woulda cost WAY more to convert my system and the technician said that it'll never blow as cold as R12 does. Since he was a HVAC only guy, who works strictly on A/C systems on cars, I kinda took his word for it.

Not really. As long as you evacuate the sytem of all R12, then it is possible to do the conversion without swapping out any components, except the lowside schrader valve fitting and orings.

well i got into a accident
and R12 was sucked out. I then did take it and got it vacuumed, and im getting the line replaced saturday as well. So i am going with 134a, i have no choice = (
is anyone using 134 ?

Yes, but mine was previously converted when I got the car, and I don't believe they did it correctly. It is adequate however. I'm sure if you have yours properly converted, it will blow nice and cold.

[Accord07]

Yeah, Its going to be done properly, plus i got a new discharge hose....
so better do some wonders !

Thats the problem. These guys are playing people. A retrofit does not cost "way" more. As a matter of fact, its cheaper than a R12 recharge (which if you charging then you are leaking).

I convert older trucks at work with the R12 system to the new R134a. We started that campaign two years ago. Reason? cutting costs. There are too many cases that contradict what these ac "specialists" are trying to sell people. R12 being colder is the only actual truth.

The bare bones minimum needed to convert is for R134A quick connect fittings to be installed and ALL the R12 refrigerant to be recovered, the system recycled and evacuated with the machine. Thats it. Replacing the drier is a plus, but not always necessary.

There are special cases, but cb7s are not one of them. Thats right you can convert a CB and have a fully functional ac without replacing a single major component.

If your ac system was empty or inop when you got your car it was compromised to begin with. what I did. Replaced my compressor(was bad), replaced compressor/condensor line(broken), replaced the schrader valve core(was leaking),retrofitted valve with quick connect fitting, removed all R12, charged with 134a. Blows colder than the central Ac in my house and my system leaks a little.

Fix the defective parts before hand. A leak in the system is obvious. People getting caked up so called black death syndrome are cobbling shit and really shouldn't be messing with the ac in the first place.

this is ture ...
as stated as long as your system has been evacuated and you use the retro kit it should be fine .

[Accord07]

my system was naturally evacuated, but its gonna get vacuumed
after i install the new AC discharge line, which cause the issue. My condensor was screwed too, so i put a new one in there as well.
compress is in good condition, and kicks on fine.

[wagonkid]

yea man go 134 its cheaper and easy to get r12 is no longer around in some ac shops E.P.A made sure of that

[Lil' Whitie]

yeah my dad said there is not much work to it. but he did mention that yo have to change the o rings at the pump tho.

my car have a leak somewhere right behind the front bumper, thats where the condenser is right?
