[C320-list] Fresh Water Engine Flush

[Christian]

"when winterizing, do you use an automotive type ethylene glycol
anti-freeze in the “fresh water” cooling circuit or a non-toxic type
anti-freeze (usually pink)?"

I don't know anyone in the area that uses eth gly type for winterizing.
Not only do you need to get it into your engine, you need to get it into
the aqua muffler too, and the eth gly type isn't even good to be pumped out
onto the ground.  I use a non toxic type, good for down to -100F, that is
green.
