    That depends on what coolant you use and how you use your truck. Any coolant will last 3 years 50,000 miles. A good quality HD coolant 5-6 years 150,000 miles. A good ELC a little longer.
    My recommendation is to flush and change your antifreeze every other year unless you are using the permanent Rotella. This will ensure that the chemical protection will not be depleted.

    My answer is from the internet, Volcane's is from a manual...I'd say go with this one.
