What does an illuminated coolant temperature light mean for my Lexus?

Pay attention to the temperature gauge and lights on your dashboard. If a low coolant warning light comes on or your dashboard temperature gauge keeps rising, it’s likely that your engine is about to overheat (and could leave you stranded on the road). Wait for the engine to cool down, then have your coolant system checked immediately at your nearest Firestone Complete Auto Care.

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.

When should my Lexus GS430 radiator be cleaned?

It could be a good idea to have your Lexus GS430 radiator cleaned out a couple of times a year, maybe at the same time as a tire rotation or oil change.

What is causing my GS430 to overheat?

One of the main reasons your Lexus GS430 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.

Why does the radiator in my GS430 sound like it’s rumbling or boiling?

If your radiator sounds like it's boiling or rumbling, you could have air pockets in the cooling system of your GS430. You might also have a damaged radiator cap (super easy to fix!) or a clogged radiator.

Is rust in my GS430 radiator bad?

Yes. Having rust in your Lexus GS430 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.

When Does My 2006 Lexus GS430 Radiator Need Service?

Not sure what a radiator does? That makes it difficult to know when to have your Lexus GS430 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.

Regular, proactive service on the radiator in your 2006 Lexus GS430 is essential for long-term engine health. To keep your radiator functioning, Lexus recommends replacing your antifreeze or coolant at scheduled intervals but it’s a good idea to keep your eyes open for any indication that your radiator is failing. You could be on the verge of a radiator-induced engine breakdown 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.
