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

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.

Can an antifreeze leak wait?

It's better to get it fixed sooner than later. Antifreeze is toxic if consumed, but its smell can attract cats and dogs. Keep your whole family safe by repairing antifreeze leaks ASAP and thoroughly hosing down your parking spot to get rid of any lingering residue on the ground.

When should my Hyundai XG350 radiator be cleaned?

To keep your Hyundai XG350 radiator running well, it’s wise to get it cleaned out a few times a year.

What can cause my XG350 to overheat?

If your Hyundai XG350 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.

What is making my XG350 radiator sound like it’s boiling or rumbling?

If your radiator sounds like it's boiling or rumbling, you could have air pockets in the cooling system of your XG350. You might also have a damaged radiator cap (super easy to fix!) or a clogged radiator.

Is rust in my XG350 radiator bad?

Yes. Having rust in your Hyundai XG350 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 2003 Hyundai XG350 Cooling System?

If you’re not sure what the purpose of a radiator is, it’s hard to tell when to have your Hyundai XG350 radiator serviced. Nonetheless, you need to know the signs of radiator malfunction. The radiator is in the cooling system of your car, and it helps your engine temperature stay within a safe range. When the radiator isn't working properly, your engine can overheat and potentially break down.

Regular, proactive service on the radiator in your 2003 Hyundai XG350 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 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. As soon as you see one of these symptoms, come to your nearest Firestone Complete Auto Care for a Courtesy Check.

What to Expect from Hyundai XG350 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 XG350’s cooling system. Then, we’ll move on to a machine-powered coolant exchange. Finally, we’ll refill the flushed sealants, lubricants and chemicals, then do a pressure check to catch any possible leaks.

If your radiator is acting up, odds are good that your water pump needs to be checked for proper function, too. Some services for your 2003 Hyundai XG350 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 vital part keeps coolant moving through the engine, hoses, and radiator. Without it, your engine won't maintain its optimal temperature. Our technicians can take a look at your radiator’s components to help you stay ahead of any potential engine problems. When it comes to radiator service and repair, we’ll take excellent care of your 2003 Hyundai XG350 at Firestone Complete Auto Care. After all, we know it’s not just a car. It’s your car.
