2019 Toyota Highlander Radiator Repair & Service

Common Toyota Highlander Radiator Questions

• Why is the coolant light on my Toyota dashboard on? If the coolant light illuminates on your dashboard, your engine could be overheating. Pull over to a safe area and wait for the engine to cool down. Then, head to your nearest Firestone Complete Auto Care for a coolant system check.
• What are the puddles in my driveway or garage floor? 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 Toyota Highlander 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 Toyota Highlander in for routine maintenance or service, it could be a good idea to opt for a radiator cleaning, too.
• Why is my Highlander overheating? One of the main reasons your Toyota Highlander 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 Highlander radiator sound like it’s boiling or rumbling? If your radiator sounds like it's boiling or rumbling, you could have air pockets in the cooling system of your Highlander. You might also have a damaged radiator cap (super easy to fix!) or a clogged radiator.
• 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.
