What can cause my Sonata to overheat?

Low coolant, a damaged cooling fan, a faulty water pump, a malfunctioning thermostat, or a clogged radiator could all cause your Hyundai Sonata engine to overheat.

What can cause a Sonata 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 Sonata. You might also have a damaged radiator cap (super easy to fix!) or a clogged radiator.

There’s rust in my Sonata radiator. Should I be worried?

Yes. Having rust in your Hyundai Sonata 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.

Is It Time for Service on My 2023 Hyundai Sonata Cooling System?

Not sure what a radiator does? That makes it difficult to know when to have your Hyundai Sonata radiator serviced, but you need to know the signs of radiator malfunction. Your radiator is part of the cooling system. It helps regulate engine temperature. When the radiator isn't working properly, your engine can overheat and potentially break down.

Keeping up with regular radiator maintenance in your 2023 Hyundai Sonata is essential for long-term engine health. Hyundai recommends that you replace coolant (also called antifreeze) at certain intervals, but you can also take note of any signs your radiator is going bad. You might be driving around (or about to be stranded) with a failing radiator if you notice a low coolant light or higher-than-normal engine temperatures on your dashboard, or if you spot coolant leaks coming from your car. When you experience one or more of these issues, head to your local Firestone Complete Auto Care for a Courtesy Check.

Our trained technicians can inspect your car’s radiator hoses and pumps to ensure everything is operating as it should.
