When Does My 2020 Lexus RX350 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 RX350 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.

Regular, proactive service on the radiator in your 2020 Lexus RX350 is crucial to keep your engine in the best possible shape for years to come. 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 a low coolant light or higher-than-normal engine temperatures on your dashboard, or if you spot coolant leaks coming from your car. Visit your local Firestone Complete Auto Care for a Courtesy Check at the first sign of one of these issues.

Lexus RX350 Coolant Fluid Exchange

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.

If your radiator is acting up, odds are good that your water pump needs to be checked for proper function, too. The water pump is one part on your 2020 Lexus RX350 engine that you can't put off repairing or replacing. 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. Let our technicians examine your radiator pumps and hoses to help make sure everything is in working order. From the radiator cap to the heater core, your 2020 Lexus RX350 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 RX350 Radiator Q&A

Wondering how to make your 2020 Lexus RX350 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 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? It's better to get it fixed sooner than later. Antifreeze is toxic if consumed, but its smell can attract cats and dogs. Keep your whole family safe by repairing antifreeze leaks ASAP and thoroughly hosing down your parking spot to get rid of any lingering residue on the ground.
  • Do Lexus RX350 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 RX350 in for routine maintenance or service, it could be a good idea to opt for a radiator cleaning, too.
  • What can cause my RX350 to overheat? One of the main reasons your Lexus RX350 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 RX350 radiator sound like it’s boiling or rumbling? Air pockets in your RX350’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.
  • Should I be concerned about rust in my RX350 radiator? Yes. Having rust in your Lexus RX350 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.
