I recently had my Honeycomb radiator re-cored and since it cost so much money I decided to ask the gentleman who specializes in manufacturing radiators what type of maintenance he would recommend to help preserve it.
He said that he is increasingly coming into more and more contact with antique buffs who swear by waterless coolants. He said that although anti-freeze has anti corrosive additives, they still break down and allow the water to corrode components over time. The waterless coolant is desinged to operate in a non-pressurized system (which mine is) and is non-corrosive.
Sounds like a good deal. Anyone have experiance or comments about it?
