When Does My 2025 Lexus NX350h Radiator Need Service?

If you’re not sure what the purpose of a radiator is, it’s hard to tell when to have your Lexus NX350h radiator serviced. Nonetheless, you need to know the signs of radiator malfunction. The radiator is in the cooling system of your car, and it helps your engine temperature stay within a safe range. So, what happens when the radiator isn’t working quite like it should? You guessed it – your engine overheats, and it may even break down completely.

Keeping up with regular radiator maintenance in your 2025 Lexus NX350h 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. When you experience one or more of these issues, head to your local Firestone Complete Auto Care for a Courtesy Check.

What happens during a radiator repair service? When you come to Firestone Complete Auto Care, we’ll begin your radiator repair with an in-depth inspection of the cooling system in your Lexus NX350h. We’ll do a machine-powered coolant exchange on the system, and then we’ll top off or replace the fluids that were removed (like chemicals, lubricants, and sealants).

Let our technicians examine your radiator pumps and hoses to help you stay ahead of any potential engine problems. When it comes to radiator service and repair, we’re here to give your 2025 Lexus NX350h the top-notch service it needs. After all, we know it’s not just a car. It’s your car.
