Is It Time for Service on My 2025 Lexus NX450h+ Cooling System?

If you’re not sure what the purpose of a radiator is, it’s hard to tell when to have your Lexus NX450h+ radiator serviced. Nonetheless, you need to know the signs of radiator malfunction. As part of your car’s cooling system, your radiator helps keep engine temperature regulated. When the radiator isn't working properly, your engine can overheat and potentially break down.

Regular, proactive service on the radiator in your 2025 Lexus NX450h+ is crucial to keep your engine in the best possible shape for years to come. Lexus recommends that you replace coolant (also called antifreeze) at certain intervals, but you can also take note of any signs your radiator is going bad. You might be driving around (or about to be stranded) with a failing radiator 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.
