When to Service Your 2020 Lexus RX450h Cooling System

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, you need to know the signs of radiator malfunction. The radiator is in the cooling system of your car, and it helps your engine temperature stay within a safe range. 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 RX450h is essential for long-term engine health. Lexus recommends that you replace coolant (also called antifreeze) at certain intervals, but it’s a good idea to keep your eyes open for any indication that your radiator is failing. You could be on the verge of a radiator-induced engine breakdown 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.

What to Expect from Lexus RX450h Radiator Repair

What does radiator repair include? At Firestone Complete Auto Care, we start by performing a thorough inspection of your Lexus RX450h 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 2020 Lexus RX450h engine that you can't put off repairing or replacing. This pump ensures that coolant is always flowing through the radiator, hoses, and engine. 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. If you’re about to lose your cool over a too-hot engine, rest assured that your 2020 Lexus RX450h is in good hands at Firestone Complete Auto Care. After all, we know it’s not just a car. It’s your car.

Common Lexus RX450h Radiator Questions

Wondering how to make your 2020 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.

  • Why is the coolant light on my Lexus dashboard on? 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? 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 RX450h 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 RX450h in for routine maintenance or service, it could be a good idea to opt for a radiator cleaning, too.
  • My RX450h 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 RX450h engine to overheat.
  • 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 it bad to have rust on my RX450h radiator? Yes. Rust in the radiator of your Lexus RX450h can impair its cooling efficiency, cause leaks, and even result in complete failure of the radiator. Over time, rust can eat away at the radiator's cooling passages, forming tiny holes or cracks that can affect its operation. To help prevent rust from causing damage, you should stay on top of radiator maintenance.
