Your owner’s manual will tell you when it’s “really” needed. Personally, I change my coolant every 2-3 years. It’s cheap insurance. Cheap compared to having to deal with a neglected cooling system, which can mean at best having to replace a clogged radiator or heater core or at worst having to replace the engine.
