Maintaining the cooling system of your Kia Seltos is essential for ensuring optimal engine performance and longevity. Flushing the coolant system helps remove rust, debris, and old coolant that can cause overheating and damage. Here’s a step-by-step guide on how to properly flush your Kia Seltos’s coolant system.

Tools and Materials Needed

  • New coolant (check your owner’s manual for the correct type)
  • Drain pan
  • Wrench set
  • Coolant flush solution (optional)
  • Hose for flushing
  • Safety gloves and goggles
  • Rags or towels

Preparation

Ensure your vehicle is on a flat surface and the engine is cool before starting. Wear safety gloves and goggles to protect against hot coolant. Gather all tools and materials beforehand for a smooth process.

Flushing Process

Drain the Old Coolant

Locate the drain plug at the bottom of the radiator. Place the drain pan underneath. Carefully loosen the drain plug using a wrench and allow the old coolant to drain completely. Dispose of the coolant responsibly according to local regulations.

Flush the System

Close the drain plug and fill the radiator with distilled water or a coolant flush solution. Start the engine and let it run for about 10 minutes with the heater on high. Turn off the engine and let it cool. Repeat the draining process to remove any remaining debris and old coolant.

Refill with New Coolant

Once the system is thoroughly flushed, close the drain plug and fill the radiator with the recommended type of coolant. Fill the overflow reservoir to the indicated level. Start the engine again and let it run with the radiator cap off to remove air pockets. Watch for bubbles and top off the coolant as needed.

Final Checks

Turn off the engine and inspect for leaks. Check the coolant level once the engine has cooled down. Properly dispose of any used coolant and clean up your workspace. Regularly flushing the coolant system helps keep your Kia Seltos running smoothly and prevents costly repairs.
