what do i need to recharge my air condition i have a 22re, and how to recharge it. i was looking at the ac system and it has 2 valves with a red cap and a blue. so which one is the one i recharge. plus i checked the compressor hoses and there in good condition
hmm if im correct, im still learning ac..u put it on the hight side, i honestly dont remember the cap color..but the only other thing is if u buy the R134 it will only let u put it on one or the other..any1 else know???
you charge the low side which is the blue line. If you have an old style R-12 system invest in the kit to swap it to R-134a. pressure check the system with some dye and charge it. If you have pressure guages charge it until the low side pressure is between 30 and 40 while the engine is at about 1500rpm and the low side guage is closed. basically add a can or so then close the low side and see where the guage goes down to. Then repeat until its right. If you have 30 to 40 on the low side it will be cold inside.
How much do the kits cost? I need to do that on mine. No AC + hot summer weather + all vinyl interior = one pissed off Sand Shark!
i went to walmart and bought a ac retrofit kit, came with hose and refriegerant and oil for 30, used it to fill my new unit, and works great, took a few mins and i was set. mine was allready retrofited, so i just used the tanks, its the best bang for the buk. 30oz of refrigerant 6oz of oil with stop leak.
Yeah in walmart, in the automotive section they have a retrofit kit for 30bucks, comes with everything you need to do it your self. kit is: R134 High PSI fitting, Low fitting. caps for those 2, 3 bottles of refrigerant with oil inside them. and the hose/gauge to apply to the ac system. once u flush out your old R12 stuff. you just install the new stuff. comes with a instructional dvd, that i never used too, lol who reads instructions anyway lol j/k have done this several times and i know what im doing lol
Technically you are supposed to have it professionally converted. The environmental protection agency would be all over your behind if they caught you releasing the old freon into the atmosphere. The correct way to do it is have a certified place evacuate the old freon correctly then service your system with old/seals etc before recharging with the new refrigerant after retrofitting. However, most people just release the valve while they pump in some of the R134 to purge the old stuff... just don't get caught. I personally was going to do that but I have a family member who owns a shop so figured it was easier and cheaper to have him do it. The kit can range from 30-50 bucks or so. I was lucky... all I needed was a recharge and my A/C has been ice cold since... been 3 months and still cold. You can find the kits at any Napa/checkers/auto zone type of store.
so what about all the accidents that happen daily? all those front end collisions that happen? were dose that freon go? i got my kit allready dissasembled then i installed it and loaded it up with new freon with the kit. works good.
Glad it worked out for you. However... I highly doubt that anyone who cared (I don't) would relate anyone purposefully releasing freon into the air to a accident such as a front end collision which still may not (or may) rupture the lines. Like I said... I don't care, I personally was going to do it that way myself... just was warning you not to get caught doing it. Glad it worked out for ya.
all new cars come with r-134 a which has a 0% ozone depletion ratio. your still not supposed to release it into the air, but it's not like r-12. i'm a welder and i had to get a/c certified at work just because i technically have access to the machines. i don't even know how to use them! but it did work out for me since i needed some r-22 for my house. without the cert you can't buy it.
