[C320-list] anti freeze

[swampcreek42]

That's probably more than what most people do. I subscribe to the same plan.

I typically drain off about 1/2 gal. of AF each year and replace with new
AF. I wonder if this is an effective procedure. Anyone have a clue?

Bill,
What color is your antifreeze? If it's the traditional green, then you
should be able to use auto antifreeze. If it's orange, then you have Dexcool
and you absolutely can't mix the two. There is often a reaction between the
two where the antifreeze jells, and ruins the engine, so be sure you know
what type of antifreeze is in your engine. Karl Mielenhausen wrote a good
article a few years ago on the procedure to change antifreeze types (it's
easy to do-I did it last fall). 

BoatUS recommends changing coolant every 2 years. The antifreeze chemicals
still work-apparently it's the lubricating chemicals that are no longer
effective. I thought every 5 years was enough....I guess I need to rethink
that.
