   That's good to know.  I could never find a "total capacity" of R134a coolant   
   for my car to know how much it can hold.  All I know is when it doesn't blow   
   "cold", takes awhile to get cool, or only blows cold on 1/2 of the vents   
   (passenger side), a 19oz can will always bring it back to life.  Sometimes a   
   regular 12oz can will do it, too.
