Charge airconditioning for saturn 2001 - 2002 Saturn L-Series

To just charge the system if it is low, then just buy a recharge kit with a pressure guage built into it. They are very common. I would buy the one with the dye and a dye detection light. Either way when you do this it goes in the low pressure side. fill it till it is to the correct pressure and the guage has pictures to show you how much to put in. The one with the dye will tell you if you have a leak and where it is. If you need to completely redo the entire system right back and tell me, but you will need more instructions.
