Finally found out where my will port is. In the passenger fender well. Sucks to get to....if you take off the wheel and peal back the wheel well it's easy to get to but I just turned the tire to the left and pealed the wheel well back a bit. A pain but I can get the r134 hose on it. I am heading to the parts store. How many cans should I get? Think it's 14oz a can. Also do I need to buy some oil or do all cans have some oil in it already? Maybe I should throw in a can of that stop leak stuff. FYI the system is bone empty. 06 ZX4 2.3l
