Don’t forget to flush.. (your coolant!)

Normal 0 false false false EN-US X-NONE X-NONE Coolant-antifreeze eventually degrades and becomes contaminated. Flush it from your cooling system as recommended in your manual (typically every two years; every five years for newer coolants). Failing to do so can damage your radiator, clog your heater core, and cause the thermostat and water pump to fail.
