What do I do with the engine coolant and AC?
warning, noob question ahead.
I'm getting ready to disassemble the HVAC in the truck an I think I'm going to have to drain the engine coolant and release the pressure on the AC. I'm not a tree huger or anything that extreme, but I try to be respectful and take care of what we have (mother earth).
Is there a better solution than just cracking the freon seal and releasing it into the air?
What do I do with the coolant once I get it drained?

Well, with regard to the coolant, the way I deal with it here is that the county transfer station (dump) has what they call the "Hazo-house". You can take bad gas, oil, or pretty much any hazardous material there (well, with the exception of weapons grade plutonium, anthrax, ricin, etc, etc, etc) and they'll dispose of it for free. I usually just take whatever it is in a 5 gallon bucket, and they'll dump it and even return the bucket if you want to keep it. So, I'd give your county waste management office a call to see what services they provide, if any.
As for the AC system, I'm not as sure how to contend with that. I know that repair shops and dealerships have reclamation equipment that can capture the gas, but I don't know for sure about any such option for the back yard do it yourself-er. If there is such an animal, I'm sure someone else here should chime in.

some systems have 'service valves' that can be closed and will hold the charge in the system and allow you to remove the compressor. or you can leave the hoses attached and wire or bungy the compressor out of the way while you do your thing.
you can catch the coolant in a drain pan and save it in milk jugs for 'topping off' or just re-use it if it's still good. never hurts to have a gallon or two on hand for emergencies.

If you have R12 still in your system take it to a shop that works on AC and have them remove it. When I was working on AC systems R12 was about $90 per pound so you might even pocket a decent amount of money, we were converting cars to 134a for free it they had 2 pounds of R12 still in they system.
