I bought a dozen new bottles of R-12 air conditioner refrigerant, for a dollar a piece at a yard sale. It's been years since I recharged my truck a/c. Can anyone step me through doing it? Seems like I ran the engine, then I unscrewed the deal on the low pressure side. Now, I can't even remember how I would know which one was the high and the low pressure side.
