Exactly.

Keep in mind that your car's maintenance schedule requires that you replace your brake fluid every two (2) years and radiator coolant every three (3) years.

If you have been lax on your coolant replacement schedule, as well as running the green stuff, your radiator could be prematurely plugged up.
