Typical recommendations for flush intervals are 2 years/30,000 miles for conventional antifreeze and 5 years/100,000-150,000 for long-life antifreeze (many of us in the field find the long-life interval to be overly optimistic).
More important than the type of antifreeze you use is to maintain the cooling system properly by maintaining freeze point protection and proper coolant level. Almost all coolants work best at the ideal freeze point mixture, which for most parts of the country means a 50/50 antifreeze-to-water mixture. At this level, antifreeze protects to -34Â°F and boil-over protection to 257Â°F.
