Why is the coolant light on my Hyundai dashboard on?

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?

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 Hyundai Sonata radiators need to be cleaned?

It could be a good idea to have your Hyundai Sonata radiator cleaned out a couple of times a year, maybe at the same time as a tire rotation or oil change.

My Sonata overheated! What can cause that?

If your Hyundai Sonata 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.

Why does the radiator in my Sonata sound like it’s rumbling or boiling?

Your Sonata’s cooling system could contain air pockets or your radiator might be clogged. Another possibility is a faulty radiator cap, which is an easy fix!

Should I be concerned about rust in my Sonata radiator?

Yes. Rust in the radiator of your Hyundai Sonata can impair its cooling efficiency, cause leaks, and even result in complete failure of the radiator. Over time, rust can eat away at the radiator's cooling passages, forming tiny holes or cracks that can affect its operation. To help prevent rust from causing damage, you should stay on top of radiator maintenance.

When Does My 2020 Hyundai Sonata Radiator Need Service?

It can be tough to know when to have your Hyundai Sonata radiator serviced if you don't know what it does, but it’s vital to know what to look for. Your radiator is part of the cooling system. It helps regulate engine temperature. If your radiator isn’t functioning like it’s supposed to, the engine can overheat – or worse, break down.

Keeping up with regular radiator maintenance in your 2020 Hyundai Sonata is a huge factor in the longevity of your engine. To keep your radiator functioning, Hyundai recommends replacing your antifreeze or coolant at scheduled intervals but it’s a good idea to keep your eyes open for any indication that your radiator is failing. You might be driving around (or about to be stranded) with a failing radiator if you see coolant leaks under your car, high engine temperatures, or a dashboard light that indicates low coolant. As soon as you see one of these symptoms, come to your nearest Firestone Complete Auto Care for a Courtesy Check.

What happens during a radiator repair service? If you bring your vehicle to Firestone Complete Auto Care, we start with a comprehensive inspection of your Hyundai Sonata’s cooling system.

Radiator problems often go hand in hand with water pump problems. The water pump is one part on your 2020 Hyundai Sonata engine that needs to be addressed ASAP once an issue is identified. The role of the water pump is to keep coolant circulating in your engine, radiator, and hoses. Without it, your engine won't maintain its optimal temperature.
