Actually, good quality anti-freeze is great stuff for preserving your
engine block, but it has little to do with the ethylene glycol other than
it helps reduce the acidity in water when it sits in the engine too long.
The main value of anti-freeze for those of us in warm climates are the
corrosion inhibitors in the anti-freeze. I believe water wetter has some
in it, but for good measure it would be interesting to call them and ask if
they have any recommendations for corrosion inhibitors. I put a zinc plug
under my radiator cap...?
I've pulled apart motors that have used too much anti-freeze, and boy, if
there's one thing it does is it helps keep the block passageways clean and
free of crud.
Water wetter? It definitely works, but you need less than
20% ethylene glycol in the system to see it work properly. It's
particularly useful in the 6-cylinder healeys in the head, it really does
wonders to keep head temps down.
