When Does My 2012 Lexus RX450h Radiator Need Service?

If you’re not sure what the purpose of a radiator is, it’s hard to tell when to have your Lexus RX450h radiator serviced. Nonetheless, it’s vital to know what to look for. Your radiator is part of the cooling system. It helps regulate engine temperature. 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.

Keeping up with regular radiator maintenance in your 2012 Lexus RX450h is crucial to keep your engine in the best possible shape for years to come. 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 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.

Radiator Repair Service for Your Lexus RX450h

What does radiator repair include? When you come to Firestone Complete Auto Care, we’ll begin your radiator repair with an in-depth inspection of the cooling system in your Lexus RX450h. We’ll do a machine-powered coolant exchange on the system, and then we’ll top off or replace the fluids that were removed (like chemicals, lubricants, and sealants). Lastly, we’ll perform a pressure check to look for leaks.

If your radiator is acting up, odds are good that your water pump needs to be checked for proper function, too. Of all the parts in your 2012 Lexus RX450h engine, the water pump is one that needs to be addressed ASAP once an issue is identified. The role of the water pump is to keep coolant circulating in your engine, radiator, and hoses. If it’s not working well (or at all), your engine can easily overheat. Our trained technicians can inspect your car’s radiator hoses and pumps to ensure everything is operating as it should. If you’re about to lose your cool over a too-hot engine, rest assured that we’re here to give your 2012 Lexus RX450h the top-notch service it needs. After all, we know it’s not just a car. It’s your car.

Lexus RX450h Radiator Q&A

Take care of your 2012 Lexus RX450h radiator and it will last. Check out our top questions and answers about Lexus radiators below, and visit your nearest Firestone Complete Auto Care at the first sign of an overheating engine.

  • 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.
  • Do Lexus RX450h radiators need to be cleaned? To keep your Lexus RX450h radiator running well, it’s wise to get it cleaned out a few times a year.
  • Why is my RX450h overheating? Your Lexus RX450h engine could overheat due to low coolant, a clogged radiator, a damaged water pump, a malfunctioning cooling fan, or a faulty thermostat.
  • What can cause a RX450h radiator to make boiling or rumbling sounds? There could be air pockets in your RX450h’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 RX450h radiator? Yes. Rust in your Lexus RX450h radiator could reduce cooling efficiency, cause leaks, and even lead to radiator failure. Left unchecked, rust can damage the radiator's cooling passages causing small holes or cracks in the radiator. Maintain your radiator system to help prevent rust.
