I am an A/C newbie, and dont know everything that i need. So i am planning on buying a 2.5cfm vacuum pump, and a A/C gauge set. i am thinking of getting this r12 set and a set of r134a quick adapters if i want to work on my wife's Ford Expedition.

What else will i need?

my 240d's situation is that the air is not cold, and i don't know the state of the compressor. i wanted to go the sanden route, but i cant commit as much money as w was hoping. i am thinking of trying to see if my current system works if i flush and recharge.
