Frequently asked questions

Frequently Asked Questions

6 common questions answered

What are the signs a 2018 Kia Optima needs a coolant service?Signs include a higher-than-usual temperature gauge, a sweet smell, or a puddle beneath the front of the vehicle.

Coolant may also look rusty or cloudy, or the reservoir level may appear low. These signs can reflect depleted coolant, a leak, or another cooling-system concern. The system is under pressure and hot after running, so checking it should be done cold rather than by opening it immediately after driving.

  • Temperature gauge running higher than usual
  • Sweet smell or a puddle under the front of the vehicle
  • Rusty, cloudy or low coolant in the reservoir
What is included in a coolant service on a 2018 Kia Optima?The service drains and refills the coolant, pressure tests the system, and inspects the hoses, cap, radiator and water pump area.

The refill uses the coolant type and concentration the manufacturer specifies for this vehicle. Pressure testing helps determine whether the system holds pressure or whether a leak needs repair. These steps assess both coolant condition and the surrounding cooling-system components.

  • Drain and refill with manufacturer-specified coolant
  • Pressure test for leaks
  • Inspect hoses, cap, radiator and water pump area
How often should the coolant in a 2018 Kia Optima be changed?The manufacturer publishes a maintenance schedule for the 2018 Kia Optima, and that schedule settles when coolant replacement is due.

Coolant condition can also be tested during a service visit between scheduled replacement points. That check can help distinguish normal maintenance from a leak or other condition affecting the system. A recurring drop in level should be inspected rather than treated as routine consumption.

  • Follow the manufacturer's maintenance schedule
  • Have coolant condition tested at a service visit
  • Investigate a level that repeatedly drops
What kind of coolant does a 2018 Kia Optima use?The manufacturer specifies the coolant type for the 2018 Kia Optima, and that specification should guide the service.

Coolants are not interchangeable, so selecting fluid by convenience can compromise the intended protection of the system. Colour is not a reliable guide to what is in the bottle. A Kia service visit can identify the correct manufacturer-specified coolant for the vehicle without relying on colour alone.

  • Use the manufacturer's specified coolant type
  • Do not assume different coolants are interchangeable
  • Do not use colour alone to identify coolant
Can I just top off the coolant in a 2018 Kia Optima?Topping off restores the coolant level but does not restore the depleted additive package, and a level that keeps dropping points to a leak that needs inspection.

The cooling system is under pressure and hot after running, so any level check should be performed cold. Adding fluid may address a low level temporarily, but it does not replace scheduled coolant service or explain why the level changed. A pressure test can help separate a maintenance need from a leak.

  • Check the system only when it is cold
  • Do not treat repeated level loss as normal consumption
  • Book an inspection if the level keeps dropping
