  1. Pull up on the release lever to open the hood.
  2. The release lever will be located on the driver's side, under the dashboard.
  3. Underneath the Hyundai symbol in the front of the car, there will be a lever. Move the lever to the side to unlock the hood, then you should be able to lift the hood up.

  7. This is the coolant reservoir, which holds your cars coolant to keep the engine from overheating during use.

  9. Open the radiator cap.
  10. Turn car off and wait 30+ minutes. This ensures the coolant is not at a dangerous temperature and pressure while opening the radiator cap.

  11. Take the cap off, pour the coolant into the tank then close the cap.
  12. The cap should be marked "Coolant" or as it says in the picture, "Engine Coolant." Consult your vehicle's service manual if you are unable to confirm this.
  13. Make sure you choose the correct coolant. Different climates require different antifreeze mixtures.
  14. Do not overfill your coolant. Check your service manual to see how much is needed. A fill line may be referenced on the coolant reservoir.

  18. Leave the engine running for 10-15 minutes more.
  19. This will let the K-Seal liquid run through and close the hole where the leakage was coming from.
