You will need a set of a/c gauges, a vacuum pump, freon and oil....... Put the gauges on both the low and high side ports (blue goes to the low side and red goes to the high side and yellow will go to the vacuum pump).... Vacuum the system down for about 1 hour and then let it sit for 1 hour to see if it will at least hold a vacuum and if so then vacuum it out for an additional 1 hour and then recharge it. Add your freon and oil at a slow pace and watch the gauge readings. Depending the outside temperature you will what the high side to be between 200 to 250psi and the low side to be between 30 to 40psi.
