To help prevent rust from causing damage, you should stay on top of radiator maintenance.

When Does My 2021 Lexus IS300 Radiator Need Service?

It can be tough to know when to have your Lexus IS300 radiator serviced if you don't know what it does, but you need to know the signs of radiator malfunction. As part of your car’s cooling system, your radiator helps keep engine temperature regulated. 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.

Regular, proactive service on the radiator in your 2021 Lexus IS300 is essential for long-term engine health. In fact, Lexus recommends replacing coolant/antifreeze at specific 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 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.

Lexus IS300 Coolant Fluid Exchange

What does radiator repair include? If you bring your vehicle to Firestone Complete Auto Care, we start with a comprehensive inspection of your Lexus IS300’s cooling system. 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). Lastly, we’ll perform a pressure check to look for leaks.

If your radiator is acting up, odds are good that your water pump needs to be checked for proper function, too. The water pump is one part on your 2021 Lexus IS300 engine that you can't put off repairing or replacing. This pump ensures that coolant is always flowing through the radiator, hoses, and engine. If it isn’t functioning properly, your engine won’t be able to stay within its optimal temperature range. Let our technicians examine your radiator pumps and hoses to help make sure everything is in working order. From the heater core to the radiator cap, we’ll take excellent care of your 2021 Lexus IS300 at Firestone Complete Auto Care. After all, we know it’s not just a car. It’s your car.
