[C320-list] Engine Winterization

[Fred Bruegmann]

Pink stuff is used routinely to winterize raw water cooled blocks,  it 
just isn't suitable for use as coolant in a fresh water (closed cooling) 
engine.  You really shouldn't use automotive antifreeze as its toxic and 
gets pumped into the water when the boat is first started after launch 
in the spring.
