I take one of the vapor hoses off and pour in some antifreeze. I have been doing this for 15 + years and never have any problems with my coolers. Not sure you need to do anything, but has been working for me. Maybe keep seals from getting dry???
Nserve is super corrosive to the internals of the cooler. Found that out the hard way.
