What does the coolant light on my Lexus dashboard mean?

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.

Can an antifreeze leak wait?

It's better to get it fixed sooner than later. Antifreeze is toxic if consumed, but its smell can attract cats and dogs. Keep your whole family safe by repairing antifreeze leaks ASAP and thoroughly hosing down your parking spot to get rid of any lingering residue on the ground.

Do Lexus IS350 radiators need to be cleaned?

It could be a good idea to have your Lexus IS350 radiator cleaned out a couple of times a year, maybe at the same time as a tire rotation or oil change.

What can cause my IS350 to overheat?

If your Lexus IS350 engine overheats, it could be because of a clogged radiator, a damaged thermostat, a faulty cooling fan, a malfunctioning water pump, or low coolant levels.

What can cause a IS350 radiator to make boiling or rumbling sounds?

There could be air pockets in your IS350’s cooling system. You might also have a clogged radiator or faulty radiator cap (this last one is an easy fix!).

Is it bad to have rust on my IS350 radiator?

Yes. Rust in the radiator of your Lexus IS350 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.

When Does My 2018 Lexus IS350 Radiator Need Service?

Not sure what a radiator does? That makes it difficult to know when to have your Lexus IS350 radiator serviced, but it’s vital to know what to look for. 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 2018 Lexus IS350 is a huge factor in the longevity of your engine. Lexus recommends that you replace coolant (also called antifreeze) at certain intervals, but you can also take note of any signs your radiator is going bad. 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. As soon as you see one of these symptoms, come to your nearest Firestone Complete Auto Care for a Courtesy Check.

What to Expect from Lexus IS350 Radiator Repair

If your radiator is acting up, odds are good that your water pump needs to be checked for proper function, too.

Let our technicians examine your radiator pumps and hoses to ensure everything is operating as it should. From the heater core to the radiator cap, your 2018 Lexus IS350 is in good hands at Firestone Complete Auto Care.
