[C320-list] Antifreeze

[Bruce Stumpp]

If I recall correctly, the Yanmar has some aluminum internals and,
therefore, requires the orange antifreeze.  Maybe someone could confirm this
but that's the rule I've followed, plus easier to use the 50-50 mix.

The article on the web site is very helpful.  I found the antifreeze issue
to be very confusing given the product changes over the years.  This is what
I've learned: 

O Don't mix colors of antifreeze;
O However, there is, apparently, a type that is compatible with any color; O
I always by the 50/50 mixture; costs more; is less trouble; avoids
minerialized (hard) water sources; O Any current product marked "extended
life" contains the anticorrosive necessary for our engines (Perkins or
Yanmar;) O To be on the safe side, follow the flushing procedure if you were
not the one who last changed the antifreeze; O Always consult and follow the
mfgr. instructions.

Once a year, I drain out 1/2 gal. of antifreeze and replace with new.  I
don't know how kosher this is; but, works for me.
