Coolant does more than keep the engine from freezing — its additives prevent corrosion inside the radiator, heater core, and water pump. After five years or so those additives are spent and the coolant starts eating the system it's supposed to protect. A flush and fill with the right type is cheap insurance.

FAQ
Coolant Flush & Fill: common questions
Can I mix coolant colors?
No. Color isn't a reliable guide anymore, and mixing chemistries causes gel that clogs the heater core. We match the specification, not the color.
