Why is the coolant light on my Lexus dashboard on?

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?

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 LX470 radiators need to be cleaned?

It could be a good idea to have your Lexus LX470 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 LX470 to overheat?

Low coolant, a damaged cooling fan, a faulty water pump, a malfunctioning thermostat, or a clogged radiator could all cause your Lexus LX470 engine to overheat.

What can cause a LX470 radiator to make boiling or rumbling sounds?

There could be air pockets in your LX470’s cooling system. You might also have a clogged radiator or faulty radiator cap (this last one is an easy fix!).

Should I be concerned about rust in my LX470 radiator?

Yes. If you have rust in your Lexus LX470 radiator, it could cause leaks, negatively impact cooling efficiency, and eventually lead to radiator failure. Left unaddressed, radiator rust can erode the cooling passages, creating cracks or small holes. Properly maintaining your radiator system can help stop it from rusting.

When Does My 2003 Lexus LX470 Radiator Need Service?

Not sure what a radiator does? That makes it difficult to know when to have your Lexus LX470 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. If your radiator isn’t functioning like it’s supposed to, the engine can overheat – or worse, break down.

Regular, proactive service on the radiator in your 2003 Lexus LX470 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 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 notice a low coolant light or higher-than-normal engine temperatures on your dashboard, or if you spot coolant leaks coming from your car. As soon as you see one of these symptoms, come to your nearest Firestone Complete Auto Care for a Courtesy Check.

Lexus LX470 Coolant Fluid Exchange

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 LX470’s cooling system. We then do a machine-powered radiator exchange, replenish flushed chemicals, sealants, and lubricants, and then pressure check for leaks.

If your radiator is acting up, odds are good that your water pump needs to be checked for proper function, too. Some services for your 2003 Lexus LX470 engine can wait, but the water pump is one part that needs to be addressed ASAP once an issue is identified. This vital part keeps coolant moving through the engine, hoses, and radiator. 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 radiator cap to the heater core, we’re here to give your 2003 Lexus LX470 the top-notch service it needs. We stand behind our work with our Triple Promise: Fixed Right, Priced Right, Right on Time.
