Is It Time for Service on My 2018 Lexus IS300 Cooling System?

It can be tough to know when to have your Lexus IS300 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. 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 IS300 is essential for long-term engine health. In fact, Lexus recommends replacing coolant/antifreeze at specific intervals, but you can also take note of any signs your radiator is going bad. Your radiator could be close to causing an engine breakdown 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.

Radiator Repair Service for Your Lexus IS300

What’s included in a radiator repair service? At Firestone Complete Auto Care, we start by performing a thorough inspection of your Lexus IS300 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 2018 Lexus IS300 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’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 we’ll take excellent care of your 2018 Lexus IS300 at Firestone Complete Auto Care. We stand behind our work with our Triple Promise: Fixed Right, Priced Right, Right on Time.

Lexus IS300 Radiator Q&A

Wondering how to make your 2018 Lexus IS300 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? 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!
  • Do Lexus IS300 radiators need to be cleaned? To keep your Lexus IS300 radiator running well, it’s wise to get it cleaned out a few times a year.
  • My IS300 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 IS300 engine to overheat.
  • What can cause a IS300 radiator to make boiling or rumbling sounds? If your radiator sounds like it's boiling or rumbling, you could have air pockets in the cooling system of your IS300. You might also have a damaged radiator cap (super easy to fix!) or a clogged radiator.
  • Should I be concerned about rust in my IS300 radiator? Yes. Rust in your Lexus IS300 radiator could reduce cooling efficiency, cause leaks, and even lead to radiator failure. Left unchecked, rust can damage the radiator's cooling passages causing small holes or cracks in the radiator. Maintain your radiator system to help prevent rust.
