Is It Time for Service on My 2018 Lexus GS450h Cooling System?

If you’re not sure what the purpose of a radiator is, it’s hard to tell when to have your Lexus GS450h radiator serviced. Nonetheless, 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.

Staying on top of routine radiator maintenance for your 2018 Lexus GS450h 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. You might be driving around (or about to be stranded) with a failing radiator if you see coolant leaks under your car, high engine temperatures, or a dashboard light that indicates low coolant. When you experience one or more of these issues, head to your local Firestone Complete Auto Care for a Courtesy Check.

Radiator Repair Service for Your Lexus GS450h

What happens during a radiator repair service? At Firestone Complete Auto Care, we start by performing a thorough inspection of your Lexus GS450h cooling system. Then, we’ll move on to a machine-powered coolant exchange. Finally, we’ll refill the flushed sealants, lubricants and chemicals, then do a pressure check to catch any possible leaks.

Radiator problems often go hand in hand with water pump problems. Of all the parts in your 2018 Lexus GS450h engine, the water pump is one that needs to be addressed ASAP once an issue is identified. This vital part keeps coolant moving through the engine, hoses, and radiator. If it’s not working well (or at all), your engine can easily overheat. Let our technicians examine your radiator pumps and hoses to help you stay ahead of any potential engine problems. From the radiator cap to the heater core, we’re here to give your 2018 Lexus GS450h the top-notch service it needs. Every job we do is backed by our Triple Promise: Fixed Right, Priced Right, Right on Time.

Questions About Lexus GS450h Radiators

Wondering how to make your 2018 Lexus GS450h radiator last as long as possible? Read on for answers to common questions, and visit your local Firestone Complete Auto Care when your engine shows any signs of a faulty radiator.

  • 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.
  • 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.
  • Do Lexus GS450h radiators need to be cleaned? To keep your Lexus GS450h radiator running well, it’s wise to get it cleaned out a few times a year.
  • My GS450h overheated! What can cause that? 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.
  • What can cause a GS450h radiator to make boiling or rumbling sounds? 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.
  • Is rust in my GS450h radiator bad? 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.
