It's been asked many times, so we went to the radiator coolant experts at Prestone to find out the shelf life of a bottle of coolant. It turns out your radiator isn't too picky how old the coolant is, because a gallon of the stuff is good for years. Even if the bottle of radiator coolant has been opened, it's good for years.

This means there's no good reason to postpone a radiator coolant check or perform a seasonal radiator flush so that your car's radiator will perform correctly and last for years and years, just like a bottle of coolant.
