coolant flush

Engine fluid replacement

A coolant flush is a maintenance procedure that drains and replaces the fluid in a vehicle's cooling system.

Unlike simply topping off coolant, a flush removes old fluid along with accumulated rust, scale, and sediment: The mechanic recommended a coolant flush every 30,000 miles.

The process typically involves running a cleaning solution through the system before adding fresh coolant.
