When Does My 2018 Lexus RX350 Radiator Need Service?

It can be tough to know when to have your Lexus RX350 radiator serviced if you don't know what it does, 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 2018 Lexus RX350 is a huge factor in the longevity of your engine. In fact, Lexus recommends replacing coolant/antifreeze at specific intervals, but it’s also wise to keep an eye out for signs of a failing radiator. 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. When you experience one or more of these issues, head to your local Firestone Complete Auto Care for a Courtesy Check.

What to Expect from Lexus RX350 Radiator Repair

What does radiator repair include? If you bring your vehicle to Firestone Complete Auto Care, we start with a comprehensive inspection of your Lexus RX350’s 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.

Issues with your radiator often coincide with a malfunctioning water pump. The water pump is one part on your 2018 Lexus RX350 engine that you can't put off repairing or replacing. This vital part keeps coolant moving through the engine, hoses, and radiator. Without it, your engine won't maintain its optimal temperature. Our trained technicians can inspect your car’s radiator hoses and pumps to help make sure everything is in working order. If you’re about to lose your cool over a too-hot engine, rest assured that we’ll take excellent care of your 2018 Lexus RX350 at Firestone Complete Auto Care. After all, we know it’s not just a car. It’s your car.

Lexus RX350 Radiator Q&A

Take care of your 2018 Lexus RX350 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 the coolant light on my Lexus dashboard mean? 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.
  • What are the puddles in my driveway or garage floor? 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!
  • Can Lexus RX350 radiators be cleaned? Cleaning your car shouldn’t be limited to the parts you can see. Regular cleaning is good for your radiator, too! When you take your Lexus RX350 in for routine maintenance or service, it could be a good idea to opt for a radiator cleaning, too.
  • My RX350 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 RX350 engine to overheat.
  • What can cause a RX350 radiator to make boiling or rumbling sounds? Your RX350’s cooling system could contain air pockets or your radiator might be clogged. Another possibility is a faulty radiator cap, which is an easy fix!
  • Is rust in my RX350 radiator bad? Yes. If you have rust in your Lexus RX350 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.
