[DML] Removing freon

[deloreanernst@xxxxxxx]

 If you are doing a body/frame separation, changing the ac compressor, replacing ac hoses or any other project that calls for your DeLorean ac system to be opened, here are some suggestions:

-Work involving possible freon release needs to be done by a licensed ac mechanic. There aren't many mechanics who can work on your gullwing doors, but there are ac mechanics everywhere.
-If your project will make the car half disassembled and undriveable for awhile, get the freon removed first, while you can still drive it to and from the ac shop.
-If you're opening the system anyway, you should definitely think about replacing the hoses, if they're original. They're available one piece like the originals or two piece for easier installation. The ac accumulator should probably be replaced too,
-The ac mechanic should see how much refrigerant is present in the system by putting a gauge on the high and low side valves. Of course you could unscrew the dust caps on the compressor yourself, press the bicycle tire type schrader valves for a split second and see if any freon poofs out, but that's actually illegal, especially if Al Gore is watching. :-p
-If your ac has been non-cooling and you have no freon left, there's nothing to save. But if there is a full  charge of freon, especially the super pricey and hard to get R12, you can save and reuse it. The ac mechanic can get an empty recycling tank intended to remove freon for recycling. It can then be pumped back into the system when it's reassembled. If there's very little left, you may want to change over to a cheaper R12 replacement refrigerant.
-Let the ac mechanic carefully break loose the hose connections... he's used to doing it.
-When ac lines are opened, have the mechanic cover the ends of hoses or other fittings so dirt and moisture can't get in. After all, you're driving the car home, and it may be awhile before you finish your project. 
-When you're ready to reassemble, the ac mechanic can pump down and recharge your system.

I think it's great to be able to do all your own mechanical work, but here's one thing I don't think it makes sense to DIY.
