The Benefits of a Radiator Flush
Flushing your radiator pushes 4 to 5 gallons of antifreeze through the system, which cleans out any old contaminants through the system. Draining the radiator doesn’t actually get the grit out. It removes about 50 percent of the antifreeze and leaves the majority of the dirt. Not only does a flush remove the dirt, but it also lubricates the water pump. It’s also a good way to get an inspection done on your system to see if there are any leaks. Plus, the new antifreeze has additives that prevent rust and build up. It’s best to have a radiator flushed about every 10,000 miles.
