Is It Time for Service on My 2020 Lexus GX460 Cooling System?

It can be tough to know when to have your Lexus GX460 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 2020 Lexus GX460 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. 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. Visit your local Firestone Complete Auto Care for a Courtesy Check at the first sign of one of these issues.

Lexus GX460 Coolant Fluid Exchange

What’s included in a radiator repair service? If you bring your vehicle to Firestone Complete Auto Care, we start with a comprehensive inspection of your Lexus GX460’s cooling system. 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.

Issues with your radiator often coincide with a malfunctioning water pump. Some services for your 2020 Lexus GX460 engine can wait, but the water pump is one part 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. If it isn’t functioning properly, your engine won’t be able to stay within its optimal temperature range. Our technicians can take a look at your radiator’s components 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 your 2020 Lexus GX460 is in good hands at Firestone Complete Auto Care. We stand behind our work with our Triple Promise: Fixed Right, Priced Right, Right on Time.

Lexus GX460 Radiator Q&A

Wondering how to make your 2020 Lexus GX460 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.
  • 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 GX460 radiators need to be cleaned? It could be a good idea to have your Lexus GX460 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 GX460 to overheat? Your Lexus GX460 engine could overheat due to low coolant, a clogged radiator, a damaged water pump, a malfunctioning cooling fan, or a faulty thermostat.
  • My GX460 radiator sounds like it's rumbling or boiling! What's up? Your GX460’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!
  • There’s rust in my GX460 radiator. Should I be worried? Yes. Having rust in your Lexus GX460 radiator can cause leaks, a reduction in cooling efficiency, and even radiator failure. If rust is left untreated, it can corrode the radiator's cooling passages, causing small cracks or holes that can significantly impact the radiator's ability to function. To help prevent rust from becoming a major issue, it's important to properly maintain your radiator system.
