Radiator Service & Repair for 2016 Toyota Avalon

Common Toyota Avalon Radiator Questions

• Why is the coolant light on my Toyota dashboard on? Your engine might be about to overheat. If your low coolant light is on, pull over in a safe area and wait for your engine temperature to go down. Once it’s safe to do so, bring your car to your nearest Firestone Complete Auto Care to have the coolant system inspected.
• Can an antifreeze leak wait? 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.
• When should my Toyota Avalon radiator 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 Avalon in for routine maintenance or service, it could be a good idea to opt for a radiator cleaning, too.
• My Avalon overheated! What can cause that? Your Toyota Avalon engine could overheat due to low coolant, a clogged radiator, a damaged water pump, a malfunctioning cooling fan, or a faulty thermostat.
• Why does the radiator in my Avalon sound like it’s rumbling or boiling? Air pockets in your Avalon’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.
• There’s rust in my Avalon radiator. Should I be worried? Yes. Having rust in your Toyota Avalon 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.
