How to check the coolant level in Kia Sportage

Regular vehicle maintenance is essential to keep your Kia Sportage running smoothly and efficiently. Checking the coolant level is a crucial part of this maintenance routine as it helps prevent your engine from overheating and potentially causing severe damage. In this article, we will guide you through the steps to check the coolant level in your Kia Sportage.

Safety Precautions

Before you begin, make sure the engine is cool to the touch. Safety should always be a top priority, so wearing safety gloves is recommended to protect your hands. If you’re working under the vehicle, safety goggles can also be used to protect your eyes from any potential splashes.

Locate the Coolant Reservoir

The coolant reservoir in a Kia Sportage is a translucent plastic container located near the engine. It is labeled with markings indicating the minimum and maximum coolant levels. Refer to your owner’s manual if you have trouble finding it.

Check the Coolant Level

With the engine off and cooled down, visually inspect the coolant level in the reservoir. The level should be between the minimum and maximum marks. If the coolant level is below the minimum mark, it’s essential to add more coolant. If it’s above the maximum mark, you may need to remove some excess coolant.

Adding Coolant

If you need to add coolant, ensure that you use the correct type recommended in your owner’s manual. To add coolant, follow these steps:

  1. Open the coolant reservoir cap slowly by rotating it counterclockwise. Be cautious, as there might still be some pressure in the system.
  2. Use a funnel if available to prevent spills. Slowly pour the coolant into the reservoir until it reaches the maximum mark. Be careful not to overfill.
  3. Screw back the reservoir cap securely by rotating it clockwise.

Use Ethylene Glycol Coolant

Your Kia Sportage comes equipped with high-quality ethylene glycol coolant in its cooling system for several important reasons:

Corrosion Prevention

Ethylene glycol coolant contains corrosion inhibitors that protect the various components of your cooling system, including the radiator, hoses, and water pump. This helps prolong the life of these parts and prevents costly repairs.


The ethylene glycol coolant also acts as a lubricant for the water pump. A well-lubricated water pump operates more efficiently and has a longer lifespan.

Freeze Protection

Ethylene glycol coolant has a lower freezing point than water, which is essential, especially in colder climates. It helps prevent the cooling system from freezing in low temperatures, which can cause significant damage.

Inspect for Leaks

After topping up the coolant, it’s a good idea to inspect the engine bay and the ground underneath your vehicle for any signs of coolant leaks. Leaks can lead to a loss of coolant over time and can result in engine overheating.

Recheck the Level

After adding coolant and ensuring there are no visible leaks, start the engine and let it run for a few minutes. This will help distribute the coolant throughout the system. Afterward, turn off the engine and recheck the coolant level. Top up if necessary.

Recheck the Reservoir Cap

Ensure that the coolant reservoir cap is tightly secured to prevent any coolant from escaping.

Check coolant level every month

Regular vehicle maintenance is crucial to ensure the longevity and optimal performance of your car. One essential aspect of this upkeep is monitoring the engine coolant level. Kia recommends checking your engine coolant level once a month to prevent overheating and potential engine damage.
