When Does My 2019 Lexus RX450h Radiator Need Service?

It can be tough to know when to have your Lexus RX450h radiator serviced if you don't know what it does, but you need to know the signs of radiator malfunction. Your radiator is part of the cooling system. It helps regulate engine temperature. 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 2019 Lexus RX450h is essential for long-term engine health. In fact, Lexus recommends replacing coolant/antifreeze at specific intervals, but it’s a good idea to keep your eyes open for any indication that your radiator is failing. You might be driving around (or about to be stranded) with a failing radiator if you notice leaking coolant, overheating, or an illuminated low coolant dashboard light. As soon as you see one of these symptoms, come to your nearest Firestone Complete Auto Care for a Courtesy Check.

Lexus RX450h Coolant Fluid Exchange

What happens during a radiator repair service? At Firestone Complete Auto Care, we start by performing a thorough inspection of your Lexus RX450h cooling system. We then do a machine-powered radiator exchange, replenish flushed chemicals, sealants, and lubricants, and then pressure check for leaks.

Issues with your radiator often coincide with a malfunctioning water pump. The water pump is one part on your 2019 Lexus RX450h engine that you'll want to have repaired or replaced as soon as you discover a problem with it. This pump ensures that coolant is always flowing through the radiator, hoses, and engine. Without it, your engine won't maintain its optimal temperature. Our technicians can take a look at your radiator’s components to help make sure everything is in working order. When it comes to radiator service and repair, we’ll take excellent care of your 2019 Lexus RX450h at Firestone Complete Auto Care. After all, we know it’s not just a car. It’s your car.

Lexus RX450h Radiator Q&A

Wondering how to make your 2019 Lexus RX450h 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.

  • 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.
  • Can an antifreeze leak wait? 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? 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 RX450h in for routine maintenance or service, it could be a good idea to opt for a radiator cleaning, too.
  • Why is my RX450h overheating? One of the main reasons your Lexus RX450h engine might overheat is because you don’t have enough coolant. Other causes include a clogged radiator, a damaged cooling fan, a malfunctioning thermostat, or a faulty water pump.
  • What is making my RX450h radiator sound like it’s boiling or rumbling? Air pockets in your RX450h’s cooling system may cause a rumbling or boiling noise. You could also have a clogged radiator or simply need to replace the radiator cap.
  • Is rust in my RX450h radiator bad? Yes. If you have rust in your Lexus RX450h 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.
