Is It Time for Service on My 2018 Lexus GS300 Cooling System?

Not sure what a radiator does? That makes it difficult to know when to have your Lexus GS300 radiator serviced, 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. 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 2018 Lexus GS300 is essential for long-term engine health. In fact, Lexus recommends replacing coolant/antifreeze at specific intervals, but it’s also wise to keep an eye out for signs of a failing radiator. You might be driving around (or about to be stranded) with a failing radiator if you notice leaking coolant, overheating, or an illuminated low coolant dashboard light. Visit your local Firestone Complete Auto Care for a Courtesy Check at the first sign of one of these issues.

What to Expect from Lexus GS300 Radiator Repair

What does radiator repair include? 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 GS300. 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. Of all the parts in your 2018 Lexus GS300 engine, the water pump is one that you can't put off repairing or replacing. The role of the water pump is to keep coolant circulating in your engine, radiator, and hoses. Without it, your engine won't maintain its optimal temperature. Our technicians can take a look at your radiator’s components to ensure everything is operating as it should. From the heater core to the radiator cap, we’ll take excellent care of your 2018 Lexus GS300 at Firestone Complete Auto Care. After all, we know it’s not just a car. It’s your car.

Lexus GS300 Radiator Q&A

Take care of your 2018 Lexus GS300 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.

  • Why is the coolant light on my Lexus dashboard on? 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.
  • Can an antifreeze leak wait? Notice a leaking fluid that's green, bright orange, or pink and feels sticky? It might be antifreeze. Antifreeze is toxic but has a sweet smell and taste that's attractive to many cats and dogs. Do your pets a favor and have an antifreeze leak investigated ASAP. Then hose down the driveway or garage floor!
  • Can Lexus GS300 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 GS300 in for routine maintenance or service, it could be a good idea to opt for a radiator cleaning, too.
  • My GS300 overheated! What can cause that? One of the main reasons your Lexus GS300 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.
  • What can cause a GS300 radiator to make boiling or rumbling sounds? There could be air pockets in your GS300’s cooling system. You might also have a clogged radiator or faulty radiator cap (this last one is an easy fix!).
  • Is rust in my GS300 radiator bad? Yes. Rust in the radiator of your Lexus GS300 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.
