my ac is kinda low on freeon i've been looking on other boards and alot of people are switching over them selfs. however, i have to change all my o rings and what about the oil in the compresser? what tools etc..

I've done the work myself. You have to replace the accumlator/dryer and the orifice tube. Poston carries these parts. The system has to be power flushed of the R-12 and the oil. The original hoses and o-rings can be used. R-134a compatible oil must be used. R-12 to R-134a adapter fittings can be purchased from any auto parts store. You'll need a vacuum pump and gages to recharge the system.

Do the flush before you install the new parts.

I'd seriously consider a drop in refrigerant. It would save time and money, also easier for you to do the recharge yourself just add it to the existing R-12

You can do a complete conversion CHEAPER than you can do a partial charge and, you don't have to worry about future R12 charges.

Acc./dryer $40.00 +/-
oil - $5.00
134 - 6.00-8.00 per pound (we take 2.6)
adapters $9.00 for the pair
Just did this before Nats...

What's R12 now? $50.00 per pound?

well i have to change all my lines being that the line that goes in to the condencer the o-ring is dry rotted.

Where to find o'rings for the a/c system? Are they a local store item or do I need to go to an a/c place to get them?
Thanks for the help.

i'm not sure are they a pain to change?

 

[bass]

I'd take the old ones in or at least the diameter sizes to a car parts dealer such as NAPA. They need to be made of the right material so the refrigerant or oil doesn't attack them.
