Should I Flush my Radiator?
Radiators. Like water in the well, we never think about them until there is a problem, usually in the dead of winter or the heatwave of summer. Do yourself a favor and pay attention to your radiator before it gives you trouble. Schedule your car in for an annual radiator flush. It can cost you anywhere from $35 to $100, but it can considerably lengthen the use you’ll get out of the radiator.
Radiator Flush vs. Radiator Drain
Keep in mind that a radiator flush is different than a radiator drain. A flush will guaranty that all of the antifreeze gets out of the system. Draining, on the other hand, only removes 50%, and most of the gunk left over is contaminants.
Flushing the radiator will remove rust and other deposits, lubricate the water pump, and protect against rust, according to Cars Direct.
