I have never done this before but it doesnt look that hard. I have an 01 SVT and I figured for and extra hundred bucks id replace the whole compressor. I am going to buy the Receiver/Drier, Accumulator, and Orifice tube also and have it vac'd and recharged by a professional. I like cold A/C! can I just let the pressure out before I get to work? then get it vac'd and recharged?
