recharging ac

[Tippey764]

thats still weak. my shit when my a/c was half gone did that.

Also: your interior temperature did not cool below 70 by much. The air blowing out of the vents might be colder then that but the interior will not cool that much due to air leakage and the sun shining inside the car

['93CB7Ex]

yea you should. but it works just as fine with r12 seals. my shits r12 seals and it worked perfect. the only time they probably need to be replaced is cuz they are old and leak. then you can rebuild the entire compressor or buy a new one. lol

wanna bet? lol

freeze12 is the same.I have never herd of compressor seals going bad because of r134a being used.But if you say so.My car has had the r134a conversion (done my way)for 2 summers in az and I drive it alot during the day when it get up to 120*f outside and it has kept me cool so far.Are you saying its going to kill my compressor?

[thepowderblue]

no you are wrong. The seals inside the compressor are not compatible with r-134A

you at minimum need to convert the compressor itself, in reality everything should be converted.

As long as you change the oil it should last. Thats what I have ben told and I have never had one go bad but you say otherwise

['93CB7Ex]

it wont kill the compressor. you need to put PAG oil in it though when you retrofit.

freeze12 is not the same, if it was it would be called r12. Basically its recycled freon from recovery tanks that has been filterd and mixed with r22 and hella other stuff. Hook up a freon analyzer to it and you will see that it is no where pure r12. IF you put that in your system and its all good then thats great. But if you ever want to recharge a system or evacuate it with a machine from another company, they wont touch it cause it will f-up their machine

93cb7ex-What I ment was the whole car gets to 70.f the air coming out of the vents is alot colder then that, I would say its about 20.f.

accordztech-I know that but it it not necessary to get your a/c blowing cold and working properly.When you vac the system it gets the moisture out. The drier, also known as the receiver-drier, is sort of the safety catch for your system. The compressor is only supposed to compress the gas form of your refrigerant. However, there's always a chance that some liquid could make it back that far. The drier catches this liquid before it can damage your compressor.Your drier also has "dessicant" (similar to that packet of "DO NOT EAT" that comes with electronics)To get any moisture let in by someone carelessly working on the system. .

Dude why go all the trouble to convert it and NOT change the reciever drier? You had it exposed to the atmosphere and in that time can dimminish that dessicant especially if its really old.

pag oil

it wont kill the compressor. you need to put PAG oil in it though when you retrofit.

Is that what the oil is called for r12? I said you had to use r12 oil but I didn't know what it it called.

Money.Why spend the extra money if you can get the a/c working fine without spending it.Why not put that money somewhere else in your car where it really counts!

['93CB7Ex]

r12 oil = mineral oil
134a oil = PAG oil

I guess if you want to be cheap and do it half ass then i guess that's OK. If you were certified like me I'd do it every time

[thepowderblue]

well.

well according to you I did everything right but change the drier.I know Its a good idea but I am kinda lazy and I didnt want to risk causing a leak or geting anything in the lines because my dryer was super dirty and it and the lines where covered in grease.All I have to say is I have no regrets because my air works good.Oh and dont they say to change your expansion valve when you switch over?

[accordztech]

Expansion valve nahh. If you feel the input high smaller hose and it is hot and then the other side low pressure isn't colder then its clogged. That's the time to change it

[lilg4mdalbc]

i use r134 on mine and i didnt change anything. when i bought the car like 4 years ago, i just got some r134, some oil, some leak sealer, charged it, and ive used it for 4 years now no problem. i would just use r134, but let the r12 or whatever out first. do it the lazy and cheap way for this like me

['93CB7Ex]

^ you can get 10 years in prison for releasing refrigerant in the air.
