I am an Italian member with little experience but a lot of fun driving my 1945 Chevy truck. I believe it is about time to flush the coolant system and replenish it with new good coolant. Many different types and products are on the market with different additives and specs. Could you please reccomend what to use end/or what not to use (please keep in mind I am in Europe not in the USA)? Is there a suggested procedure on how to do it properly? The liquid presently in the engine and in the radiator is about three years old. Shouln't be too bad.
