I want to recharge my A/C but I wanna know what kind of FREON or recharging kit I should use??? I have a 134a Recharging kit that I got from Auto ZOne that I was going to put into my girls Focus but it wasn't going to work so I was wondering if I can use that kit for my car>>>>>By the way I have a 91 Civic Hatch DX 4 Speed Front Wheel Drive<<<<<<< :af:
