I bought an EG that had all the A/C lines and everything taken out, for whatever reason, but I can't take the heat anymore so i purchased all the a/c lines, compressor, etc off of ebay. I had heard that if they are out of the car for a period of time they can become contaminated.. I'm not sure if these are contaminated or not, but I will assume they are. What is the best way to clean them out, uncontaminate them, I have heard mineral spirits will work, and maybe some compressed nitrogen, since nitrogen doesn't have any moisture in it like regular compressed air. Anyone know or have installed used ac parts on thier cars?? thanks

 

If its out of the car then just shoot it with some parts cleaner and let it dry then put a cap on both ends.

make sure you get a NEW reciever drier for the type of refigerant your going to use i.e. R12 or R134A.

Now also When you do get everything installed it is a good thing to blow some nitrogen through the system.

 

What do you mean by "some parts cleaner"? Sorry for the silly question, but I'm dutch and don't get it.

 

if you're talking about just the lines and you're talking about getting dirt and stuff out of them just use some water. Doesn't hurt anything. Even for the condenser and evap you can use water. No harm done. when you install the system make sure that the shop pulls a good vacuum on the system. Then they should charge it with nitrogen and. Repeat this process about 3 or 4 times to get all the moisture out. Make sure they install a new receiver/drier like BatuKing said. But if you have a reputable shop do it you shouldn't have any problems.
Before you ask, unless you have all the right equipment (vacuum pump, nitrogen bottle, gauges, oil pump, refrigerant scale) don't even ask about doing this yourself. You'll be on here asking "what's wrong with my AC system" in a couple days.

 

Wasn't thinking of filling it myself. Just of installing it myself.

I have a Del Sol without a/c and want to install a used OEM system. Not a simple task if I study the drawings and electrical diagrams. I worry that the electrical harness isn't prepped for an a/c. That would be a major setback. Even so, I need to take the dashboard out to install the evaporator, and some small parts like the thermostat.

Is this doable for a handyman, or am I out of my mind to contemplate this?
