A/C restoration
I need tips from people that have brought A/C systems back from the dead.
My system has been open for over a year now. I need to replace the condenser, compressor, and drier for starters. Along with all applicable o-rings.
Should I flush out the evaporator and lines that have remained on the car? I am worried that if I flush it out, there will be too much moisture left over.

all i can really tell you is that you dont need to switch the system over to the r-134 or whatever it is. they just say you need to convert but its all a money scheme. just use the new stuff. it works jus tthe same

flush the pipes with mineral spirits and an air-compressor blow gun. Blow the mineral spirits through until you get clear mineral spirits from the other end. Try to blow it dry. The rest will be removed with the vacuum pump.
Don't flush the condenser, through the expansion valve, the evaporator or the compressor in this way. If you remove the components from the car, you can *try* to flush the condenser and the evaporator.
Flush the compressor (off the car) by adding 3-4 oz of fresh clean Ester oil, rotating the compressor by hand 10-12 times, then dumping the oil out. Repeat this 2-3 more times-at minimum until the oil drains out clean.
Replace all the orings to components you have taken apart. Buy a 'master kit' at autozone or oriellies. It will have all the orings you will need for the rest of your life.
Don't buy your drier by mailorder. Buy it locally so you can take your old drier with you to the parts store and match it up. Other wise, you will probably get home with the wrong one and have to go back.
Use Ester oil for your new oil-3 oz in the compressor and 3 oz in the new drier.
If you want a little help and some R12, pm me. I would be willing to help you out on the last stage, pull a vacuum charge etc.
