Raleesh, check the above quote, you have the same problem, a gas converter/valve has to be installed to fill the new R13 gas. The valve,gas and the cleaning labor will cost you to 5500/6000k.
Without installing the valve it is a waste filling the new gas, the gas will leakout gradually resulting to less cooling, if not refilled the gas will leak out completely.This is because the valve in your car cannot hold R13 it can only hold R12.
same thing is on old Zen,so if you really want your problem solved change the gas converter/valve instead of wasting your money on the refill of the gas.
