When Does My 2023 Lexus LS500 Radiator Need Service?

Not sure what a radiator does? That makes it difficult to know when to have your Lexus LS500 radiator serviced, but it's still extremely important. 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.

Staying on top of routine radiator maintenance for your 2023 Lexus LS500 is essential for long-term engine health. 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. 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.

What to Expect from Lexus LS500 Radiator Repair

What’s included in 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 LS500. Then, we’ll move on to a machine-powered coolant exchange. Finally, we’ll refill the flushed sealants, lubricants and chemicals, then do a pressure check to catch any possible leaks.

If your radiator is acting up, odds are good that your water pump needs to be checked for proper function, too. Of all the parts in your 2023 Lexus LS500 engine, the water pump is one 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’s not working well (or at all), your engine can easily overheat. Our technicians can take a look at your radiator’s components to ensure everything is operating as it should. From the radiator cap to the heater core, your 2023 Lexus LS500 is in good hands at Firestone Complete Auto Care. After all, we know it’s not just a car. It’s your car.

Lexus LS500 Radiator Q&A

With regular maintenance and service as needed, you could extend the life of your 2023 Lexus LS500 radiator. Get answers to common radiator questions, and head to your nearest Firestone Complete Auto Care as soon as you suspect a radiator issue.

  • What does an illuminated coolant temperature light mean for my Lexus? If the coolant light illuminates on your dashboard, your engine could be overheating. Pull over to a safe area and wait for the engine to cool down. Then, head to your nearest Firestone Complete Auto Care for a coolant system check.
  • Is an antifreeze leak dangerous? Don’t ignore puddles on your driveway or garage floor. If you see a green, bright orange, or pink fluid puddling under your car (it might be sticky, too), it could be antifreeze that’s leaking out of the engine. Antifreeze has a sweet, attractive smell to cats and dogs (and it’s highly toxic to them), so look out for your pets! Repair any leaks as soon as possible, then carefully wash away any remaining fluid that’s left behind on the driveway or garage floor.
  • Can Lexus LS500 radiators be cleaned? To keep your Lexus LS500 radiator running well, it’s wise to get it cleaned out a few times a year.
  • What can cause my LS500 to overheat? One of the main reasons your Lexus LS500 engine might overheat is because you don’t have enough coolant. Other causes include a clogged radiator, a damaged cooling fan, a malfunctioning thermostat, or a faulty water pump.
  • My LS500 radiator sounds like it's rumbling or boiling! What's up? There could be air pockets in your LS500’s cooling system. You might also have a clogged radiator or faulty radiator cap (this last one is an easy fix!).
  • There’s rust in my LS500 radiator. Should I be worried? Yes. Rust in the radiator of your Lexus LS500 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.
