Best Answer

With the engine running and the ac on, Find the low pressure port on the ac lines depending on your engine ( it usually has a screw on cap with the letter l on it ) and using the hose supplied in the r134a recharge kit that you will buy at the parts store connect the hose to the coupling ( it works like an air hose ) open the valve on the can and the r134 will flow into your car by itself and remember to keep the can upright so only gas enters and not liquid, you can shake it some to speed up the process ( notice that the can gets cold ). When the air runs cold you have enough, you will not always need the whole can and sometimes you will need 2, If there is a leak in the system have it repaired asap dont keep refilling it. another answer when you buy the recharge kit, buy the one that has the refrigerant oil and a dye in it it will all be in same can people do not realize the system needs the oil to transport the gas. the dye will show up if there are any leaks in your system, also you need to make sure you do not over charge your system there is a small glass in the system if you cannot see a bubble as you see in a builders level u have eithe to much or to little . that is only way to tell if you dont have the gauges to hook uo that professionals use
