Is It Time for Service on My 2021 Lexus ES350 Cooling System?

It can be tough to know when to have your Lexus ES350 radiator serviced if you don't know what it does, but you need to know the signs of radiator malfunction. Your radiator is part of the cooling system. It helps regulate engine temperature. When the radiator isn't working properly, your engine can overheat and potentially break down.

Regular, proactive service on the radiator in your 2021 Lexus ES350 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 it’s a good idea to keep your eyes open for any indication that your radiator is failing. Your radiator could be close to causing an engine breakdown if you see coolant leaks under your car, high engine temperatures, or a dashboard light that indicates low coolant. As soon as you see one of these symptoms, come to your nearest Firestone Complete Auto Care for a Courtesy Check.
