What does the coolant light on my Hyundai dashboard mean?

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.

What are the puddles in my driveway or garage floor?

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.

Why is my Sonata overheating?

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?

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!).

Is rust in my Sonata radiator bad?

Yes. Rust in your Hyundai Sonata radiator could reduce cooling efficiency, cause leaks, and even lead to radiator failure. Left unchecked, rust can damage the radiator's cooling passages causing small holes or cracks in the radiator. Maintain your radiator system to help prevent rust.

When to Service Your 2018 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 still extremely important. The radiator is in the cooling system of your car, and it helps your engine temperature stay within a safe range. 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 2018 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 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. Visit your local Firestone Complete Auto Care for a Courtesy Check at the first sign of one of these issues.

Radiator Repair Service for Your Hyundai Sonata

What does radiator repair include? When you come to Firestone Complete Auto Care, we’ll begin your radiator repair with an in-depth inspection of the cooling system in your Hyundai Sonata. 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. Of all the parts in your 2018 Hyundai Sonata engine, the water pump is one that you can't put off repairing or replacing. The role of the water pump is to keep coolant circulating in your engine, radiator, and hoses. If it’s not working well (or at all), your engine can easily overheat. Our trained technicians can inspect your car’s radiator hoses and pumps to help make sure everything is in working order. If you’re about to lose your cool over a too-hot engine, rest assured that your 2018 Hyundai Sonata is in good hands at Firestone Complete Auto Care. We stand behind our work with our Triple Promise: Fixed Right, Priced Right, Right on Time.
