Man I need to go to that shop, I have done hundreds of 140 evaps over the years and it is only a 18 hr job . Yea its alot to do but not really that hard. It shouldnt take over a day to do it. Most shops and dealers are at 18 now, add reciever drier thats .8 , add evacuate and recharge and thats another 1.4 . Add it up and it is 20.2 so shop before you drop that money in it.
