What does the coolant light on my Hyundai dashboard mean?

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.

What are the puddles in my driveway or garage floor?

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?

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.

What can cause my Sonata to overheat?

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.

My Sonata radiator sounds like it's rumbling or boiling! What's up?

There could be air pockets in your Sonata’s cooling system. You might also have a clogged radiator or faulty radiator cap (this last one 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.

Is It Time for Service on My 1991 Hyundai Sonata Cooling System?

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. As part of your car’s cooling system, your radiator helps keep engine temperature regulated. 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.

Regular, proactive service on the radiator in your 1991 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 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 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.

Hyundai Sonata Coolant Fluid Exchange

What happens during a radiator repair service? At Firestone Complete Auto Care, we start by performing a thorough inspection of your Hyundai Sonata cooling system. We then do a machine-powered radiator exchange, replenish flushed chemicals, sealants, and lubricants, and then pressure check for leaks.

If your radiator is acting up, odds are good that your water pump needs to be checked for proper function, too. Of all the parts in your 1991 Hyundai Sonata engine, the water pump is one that you'll want to have repaired or replaced as soon as you discover a problem with it. The role of the water pump is to keep coolant circulating in your engine, radiator, and hoses. If it isn’t functioning properly, your engine won’t be able to stay within its optimal temperature range. Our trained technicians can inspect your car’s radiator hoses and pumps to help you stay ahead of any potential engine problems. If you’re about to lose your cool over a too-hot engine, rest assured that we’ll take excellent care of your 1991 Hyundai Sonata at Firestone Complete Auto Care. After all, we know it’s not just a car. It’s your car.
