Air pockets in your ES300h’s cooling system may cause a rumbling or boiling noise. You could also have a clogged radiator or simply need to replace the radiator cap.

Should I be concerned about rust in my ES300h radiator?

Yes. Rust in the radiator of your Lexus ES300h can impair its cooling efficiency, cause leaks, and even result in complete failure of the radiator. Over time, rust can eat away at the radiator's cooling passages, forming tiny holes or cracks that can affect its operation. To help prevent rust from causing damage, you should stay on top of radiator maintenance.

When to Service Your 2020 Lexus ES300h Cooling System

It can be tough to know when to have your Lexus ES300h 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. When the radiator isn't working properly, your engine can overheat and potentially break down.

Keeping up with regular radiator maintenance in your 2020 Lexus ES300h 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 also wise to keep an eye out for signs of a failing radiator. 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.

Lexus ES300h Coolant Fluid Exchange

What does radiator repair include? At Firestone Complete Auto Care, we start by performing a thorough inspection of your Lexus ES300h cooling system.
