Most Important Fall Maintenance: The Radiator Flush

By October 11, 2010

Follow me on:

With cooler weather on the horizon, it's time to be sure your car or truck is ready for its annual wrestling match with old man winter. Of all the seasonal maintenance procedures you can -- and need -- to perform, I think the radiator flush is the most important. You may be thinking, "Duh Matt, it's called 'antifreeze.' You're such a genius." You're right, it seems like the obvious choice. But checking your coolant (or antifreeze, same thing) level and mixture isn't enough. It's super important to clean this system out with a proper flush. Aging coolant can be terrible for your cooling system. I've seen heater cores eaten away with pinholes thanks to lack of cleaning. If you do only one maintenance procedure this year, shame on you, but let it be a coolant flush!

what’s your thought of running the radiator flush solution in the radiator for 100 miles or so…?

Any detremental effects? I’ve heard of some people going this route for an “extended cleaning”…..but my theory is the whole hot to cold, hot to cold over those 100 miles, would just put the “cleaned up” mess somewhere else within the system.

Your thoughts?
