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?

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!

When should my Lexus GS450h radiator be cleaned?

It could be a good idea to have your Lexus GS450h 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 GS450h to overheat?

Low coolant, a damaged cooling fan, a faulty water pump, a malfunctioning thermostat, or a clogged radiator could all cause your Lexus GS450h engine to overheat.

My GS450h radiator sounds like it's rumbling or boiling! What's up?

If your radiator sounds like it's boiling or rumbling, you could have air pockets in the cooling system of your GS450h. You might also have a damaged radiator cap (super easy to fix!) or a clogged radiator.

Should I be concerned about rust in my GS450h radiator?

Yes. Rust in the radiator of your Lexus GS450h 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 to Service Your 2009 Lexus GS450h Cooling System

Not sure what a radiator does? That makes it difficult to know when to have your Lexus GS450h radiator serviced, but it’s vital to know what to look for. The radiator is in the cooling system of your car, and it helps your engine temperature stay within a safe range. If your radiator isn’t functioning like it’s supposed to, the engine can overheat – or worse, break down.

Keeping up with regular radiator maintenance in your 2009 Lexus GS450h is a huge factor in the longevity of your engine. To keep your radiator functioning, Lexus recommends replacing your antifreeze or coolant at scheduled intervals but it’s also wise to keep an eye out for signs of a failing radiator. Your radiator could be close to causing an engine breakdown if you notice a low coolant light or higher-than-normal engine temperatures on your dashboard, or if you spot coolant leaks coming from your car. When you experience one or more of these issues, head to your local Firestone Complete Auto Care for a Courtesy Check.
