50% is what the Service DVD recommends.
Dave
50% is the MINIMUM required protection...you can achieve better coolant
and antifreeze capablity w/ the GOLD coolant...the maximum amount of
protection is up to 70%....beyond 70% you actually reduce the cooling
capablities.
the maximum amount of protection for G05/Gold is at 70% strength...
youll get better cooling protection (and anti-freeze) protection if you
mix it to 70% strength.
w/ the G05 Zerex bottle in hand look at the calculation for boiling point
and freeze points & youll see what im talking about.
