Is It Time for Service on My 2019 Lexus IS300 Cooling System?

If you’re not sure what the purpose of a radiator is, it’s hard to tell when to have your Lexus IS300 radiator serviced. Nonetheless, you need to know the signs of radiator malfunction. As part of your car’s cooling system, your radiator helps keep engine temperature regulated. If your radiator isn’t functioning like it’s supposed to, the engine can overheat – or worse, break down.

Staying on top of routine radiator maintenance for your 2019 Lexus IS300 is a huge factor in the longevity of your engine. In fact, Lexus recommends replacing coolant/antifreeze at specific 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. As soon as you see one of these symptoms, come to your nearest Firestone Complete Auto Care for a Courtesy Check.

Radiator Repair Service for Your Lexus IS300

What happens during a radiator repair service? 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.

Issues with your radiator often coincide with a malfunctioning water pump. Some services for your 2019 Lexus IS300 engine can wait, but the water pump is one part that you'll want to have repaired or replaced as soon as you discover a problem with it. This vital part keeps coolant moving through the engine, hoses, and radiator. Without it, your engine won't maintain its optimal temperature. Our trained technicians can inspect your car’s radiator hoses and pumps to help make sure everything is in working order. From the heater core to the radiator cap, your 2019 Lexus IS300 is in good hands at Firestone Complete Auto Care. After all, we know it’s not just a car. It’s your car.

Lexus IS300 Radiator Q&A

Take care of your 2019 Lexus IS300 radiator and it will last. Check out our top questions and answers about Lexus radiators below, and visit your nearest Firestone Complete Auto Care at the first sign of an overheating engine.

  • What does an illuminated coolant temperature light mean for my Lexus? Your engine might be about to overheat. If your low coolant light is on, pull over in a safe area and wait for your engine temperature to go down. Once it’s safe to do so, bring your car to your nearest Firestone Complete Auto Care to have the coolant system inspected.
  • What are the puddles in my driveway or garage floor? 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 IS300 radiators be cleaned? Cleaning your car shouldn’t be limited to the parts you can see. Regular cleaning is good for your radiator, too! When you take your Lexus IS300 in for routine maintenance or service, it could be a good idea to opt for a radiator cleaning, too.
  • Why is my IS300 overheating? Low coolant, a damaged cooling fan, a faulty water pump, a malfunctioning thermostat, or a clogged radiator could all cause your Lexus IS300 engine to overheat.
  • What is making my IS300 radiator sound like it’s boiling or rumbling? Air pockets in your IS300’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.
  • Is it bad to have rust on my IS300 radiator? Yes. Having rust in your Lexus IS300 radiator can cause leaks, a reduction in cooling efficiency, and even radiator failure. If rust is left untreated, it can corrode the radiator's cooling passages, causing small cracks or holes that can significantly impact the radiator's ability to function. To help prevent rust from becoming a major issue, it's important to properly maintain your radiator system.
