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.

Radiator Repair Service for Your Hyundai Sonata

What’s included in 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.

Radiator problems often go hand in hand with water pump problems. Some services for your 2023 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. Without it, your engine won't maintain its optimal temperature. Our trained technicians can inspect your car’s radiator hoses and pumps to ensure everything is operating as it should. If you’re about to lose your cool over a too-hot engine, rest assured that your 2023 Hyundai Sonata is in good hands at Firestone Complete Auto Care. After all, we know it’s not just a car. It’s your car.

Questions About Hyundai Sonata Radiators

With regular maintenance and service as needed, you could extend the life of your 2023 Hyundai Sonata radiator. Get answers to common radiator questions, and head to your nearest Firestone Complete Auto Care as soon as you suspect a radiator issue.

  • What does an illuminated coolant temperature light mean for my Hyundai? 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.
  • Is an antifreeze leak dangerous? Notice a leaking fluid that's green, bright orange, or pink and feels sticky? It might be antifreeze. Antifreeze is toxic but has a sweet smell and taste that's attractive to many cats and dogs. Do your pets a favor and have an antifreeze leak investigated ASAP. Then hose down the driveway or garage floor!
  • When should my Hyundai Sonata 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 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? 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.
