Why is the coolant light on my Kia dashboard on?

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.

Is It Time for Service on My 2017 Kia Optima Cooling System?

It can be tough to know when to have your Kia Optima radiator serviced if you don't know what it does, but it's still extremely important. As part of your car’s cooling system, your radiator helps keep engine temperature regulated. If your radiator isn’t functioning like it’s supposed to, the engine can overheat – or worse, break down.

Keeping up with regular radiator maintenance in your 2017 Kia Optima is a huge factor in the longevity of your engine. To keep your radiator functioning, Kia recommends replacing your antifreeze or coolant at scheduled 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. Visit your local Firestone Complete Auto Care for a Courtesy Check at the first sign of one of these issues.

What to Expect from Kia Optima Radiator Repair

What’s included in a radiator repair service? At Firestone Complete Auto Care, we start by performing a thorough inspection of your Kia Optima cooling system. We’ll do a machine-powered coolant exchange on the system, and then we’ll top off or replace the fluids that were removed (like chemicals, lubricants, and sealants). Lastly, we’ll perform a pressure check to look for leaks.

Issues with your radiator often coincide with a malfunctioning water pump. Some services for your 2017 Kia Optima 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. Let our technicians examine your radiator pumps and hoses to ensure everything is operating as it should. When it comes to radiator service and repair, your 2017 Kia Optima is in good hands at Firestone Complete Auto Care. After all, we know it’s not just a car. It’s your car.
