Steps to Check and Maintain Coolant Levels in Your Sonata

Checking and maintaining the coolant levels in your Sonata is a simple yet crucial step in ensuring your engine stays cool and efficient, with a properly functioning radiator preventing overheating. Neglecting coolant maintenance can lead to costly repairs and even engine failure.

To check the coolant level in your Sonata, start by locating the coolant reservoir under the hood. Make sure the engine is cool before removing the cap. The coolant level should be between the ‘MIN’ and ‘MAX’ marks on the reservoir. If it’s below the minimum mark, add a mixture of 50% antifreeze and 50% distilled water until it reaches the desired level.

Regularly checking your coolant level is important to prevent potential issues such as low coolant or leaks that could lead to engine damage.
