Is It Time for Service on My 2018 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 vital to know what to look for. The radiator is in the cooling system of your car, and it helps your engine temperature stay within a safe range. If your radiator isn’t functioning like it’s supposed to, the engine can overheat – or worse, break down.

Staying on top of routine radiator maintenance for your 2018 Kia Optima is crucial to keep your engine in the best possible shape for years to come. To keep your radiator functioning, Kia recommends replacing your antifreeze or coolant at scheduled intervals but it’s a good idea to keep your eyes open for any indication that your radiator is failing. You could be on the verge of a radiator-induced engine breakdown if you notice leaking coolant, overheating, or an illuminated low coolant dashboard light. As soon as you see one of these symptoms, come to your nearest Firestone Complete Auto Care for a Courtesy Check.

Kia Optima Coolant Fluid Exchange

What does radiator repair include? If you bring your vehicle to Firestone Complete Auto Care, we start with a comprehensive inspection of your Kia Optima’s 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. Some services for your 2018 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. Our technicians can take a look at your radiator’s components 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 your 2018 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.

Questions About Kia Optima Radiators

Take care of your 2018 Kia Optima radiator and it will last. Check out our top questions and answers about Kia radiators below, and visit your nearest Firestone Complete Auto Care at the first sign of an overheating engine.

  • What does an illuminated coolant temperature light mean for my Kia? Your engine might be about to overheat. If your low coolant light is on, pull over in a safe area and wait for your engine temperature to go down. Once it’s safe to do so, bring your car to your nearest Firestone Complete Auto Care to have the coolant system inspected.
  • Can an antifreeze leak wait? 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!
  • Can Kia Optima radiators 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 Kia Optima in for routine maintenance or service, it could be a good idea to opt for a radiator cleaning, too.
  • What can cause my Optima to overheat? Your Kia Optima engine could overheat due to low coolant, a clogged radiator, a damaged water pump, a malfunctioning cooling fan, or a faulty thermostat.
  • What is making my Optima radiator sound like it’s boiling or rumbling? There could be air pockets in your Optima’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 Optima radiator bad? Yes. Rust in your Kia Optima 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.
