Default Re: Best Anti-Freeze

When I used the coupe as a daily driver I used Prestone antifreeze. It almost never goes to zero here . You would need to use a tester to determine the ratio of water to antifreeze . I used one gallon of Prestone with two gallons of water. I only used antifreeze in winter .Antifreeze raises the boiling point but doesn't raise the cooling ability . Modern cars need to run at higher temps than the primitive cooling system of the model A .
