60% Water to 50% Water with 40 or 50 % of antifreeze... is what you want . Why ? because the antifreeze protects the Waterpump....helps against rust and raises the boiling point of your coolant !
and stay with one product only...do not add or mix or whatever.. keep it simple !!
you can run 80% or 90% water when warm, and use a bottle of Purple Ice
for corrosion protection.
