What does an illuminated coolant temperature light mean for my Hyundai?

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.

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?

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 Hyundai Sonata in for routine maintenance or service, it could be a good idea to opt for a radiator cleaning, too.

What can cause my Sonata to overheat?

One of the main reasons your Hyundai Sonata 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 Sonata radiator sound like it’s boiling or rumbling?

Air pockets in your Sonata’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 Sonata radiator. Should I be worried?

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.

Is It Time for Service on My 2012 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. So, what happens when the radiator isn’t working quite like it should? You guessed it – your engine overheats, and it may even break down completely.

Staying on top of routine radiator maintenance for your 2012 Hyundai Sonata is crucial to keep your engine in the best possible shape for years to come. Hyundai recommends that you replace coolant (also called antifreeze) at certain intervals, but it’s also wise to keep an eye out for signs of a failing radiator. You could be on the verge of a radiator-induced engine breakdown 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.

What to Expect from Hyundai Sonata Radiator Repair

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. We then do a machine-powered radiator exchange, replenish flushed chemicals, sealants, and lubricants, and then pressure check for leaks.

Issues with your radiator often coincide with a malfunctioning water pump. Some services for your 2012 Hyundai Sonata engine can wait, but the water pump is one part that you'll want to have repaired or replaced as soon as you discover a problem with it. This pump ensures that coolant is always flowing through the radiator, hoses, and engine. If it’s not working well (or at all), your engine can easily overheat. Our technicians can take a look at your radiator’s components to help make sure everything is in working order. From the heater core to the radiator cap, we’ll take excellent care of your 2012 Hyundai Sonata at Firestone Complete Auto Care. We stand behind our work with our Triple Promise: Fixed Right, Priced Right, Right on Time.
