I am trying to get my AC system to function. And change it to 134a. So I bought this new Four Seasons compressor, But the labels are confusing me.The yellow label says it comes charged with PAG 46. But there is also a pink lable that says to add more oil in the side filler hole. HOw do I know how much oil to add? And when I install it into. the truck what prevents oil from leaking out the back. Obviously I have never done this before or I would not be so confused.
