Radiator Service & Repair for 2017 Toyota Highlander

Toyota Highlander Radiator Q&A

• What does an illuminated coolant temperature light mean for my Toyota? 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.
• Can Toyota Highlander radiators be cleaned? It could be a good idea to have your Toyota Highlander radiator cleaned out a couple of times a year, maybe at the same time as a tire rotation or oil change.
• What is causing my Highlander to overheat? If your Toyota Highlander engine overheats, it could be because of a clogged radiator, a damaged thermostat, a faulty cooling fan, a malfunctioning water pump, or low coolant levels.
• My Highlander radiator sounds like it's rumbling or boiling! What's up? Air pockets in your Highlander’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 Highlander radiator bad? Yes. If you have rust in your Toyota Highlander 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.
