i didnt read anything that says this coolant protects aluminum.
heavy construction equiptment might have no aluminum at all
excepting radiator fins.
with evans waterless coolant in a non pressuried system there
would be no cavitation.
cavitation is a surface metal reaction to a very strong vacuum,
where molecues are phyically pulled off. if the ford coolant
system, pressuried at 15-30psi is damaged by cavitation, then
they must have used really poor quality metal (aluminum?)
