Mazda is one car manufacturer that believes in their social responsibilities as seen on the products and innovations that they continuously pursue and develop. Their auto parts are made from the highest quality as seen in one such part, the AC receiver drier. The AC receiver drier has two functions. Primarily, it should separate the gas and the liquid. Second, it is supposed to remove moisture and filter out dirt and other contaminants that may plug the AC system. It is located in the engine compartment, a cylindrical looking part that should be painted black, and has two hose attached to it. At the top of the receiver drier is a sight glass or a small window that is used to charge the system or allows you to see if the AC is fully charged. Under normal situations, you should not see any bubbles passing thru the receiver drier. If you see any bubbles then that would mean you are already low on Freon. There are different types of AC receiver-driers that use different desiccant materials. It would be best to ask the help of a certified AC specialist when changing your AC receiver drier as this can help avoid further accidents that can hurt you or that can accidentally discharge AC refrigerant to the ozone. The AC receiver drier should be changed every time you remove any AC component that exposes the sealed AC system to the atmosphere.
