How much freon does the 2010 Ford Focus take?

The 2010 Ford Focus sues 18 ounces of R-134A freon for the AC system. In general if You have a freon leak You will want to get it inspected by a professional so that it can be fixed properly. Adding freon should also be done using a freon exchange tool. That tool will remove all the freon from Your car, then refill it with the correct amount so that You know that it is full. The freon cans that are on the market can be inaccurate and that can lead to an overcharge or undercharge of Your system which will make it not work properly. Another good reason to let a professional inspect it is releasing freon into the atmosphere is crime. If there is a known leak in Your system and You just add more freon it will simply leak out and add more pollution to the air.
