When to Service Your 2021 Lexus NX300h Cooling System

It can be tough to know when to have your Lexus NX300h radiator serviced if you don't know what it does, but it's still extremely important. The radiator is in the cooling system of your car, and it helps your engine temperature stay within a safe range. If your radiator isn’t functioning like it’s supposed to, the engine can overheat – or worse, break down.

Keeping up with regular radiator maintenance in your 2021 Lexus NX300h is crucial to keep your engine in the best possible shape for years to come. In fact, Lexus recommends replacing coolant/antifreeze at specific intervals, but you can also take note of any signs your radiator is going bad. Your radiator could be close to causing an engine breakdown if you notice a low coolant light or higher-than-normal engine temperatures on your dashboard, or if you spot coolant leaks coming from your car. As soon as you see one of these symptoms, come to your nearest Firestone Complete Auto Care for a Courtesy Check.
