John, I used to always mix coolant with water, especially in the summer to
increase the heat capacity of the fluid, but my a vanagon mechanic told my
always to use straight stuff, and thats waht I've been running on for years.
(not to say I haven't had any probs with the cooling system, I ahve had lots
of them. Does anybody have a solid recc on what are the conseqences of a
100% coolant ration vs 50/50 water.

I'm also interested in the recent posting on the non-aqueous coolant that
?decreases head corrosion?

Coolant to water ratio is out of balance. I can't say enough about this.
