Hyundai Elantra (CN7): Maintenance / Engine Coolant

The high-pressure cooling system has a reservoir filled with year-round antifreeze coolant. The reservoir is filled at the factory.

Check the antifreeze protection and coolant level at least once a year, at the beginning of the winter season and before traveling to a colder climate.

NOTICE

• When the engine overheats from low engine coolant, suddenly adding engine coolant may cause cracks in the engine. To prevent damage, add engine coolant slowly in small quantities.
• Do not drive with no engine coolant. It may cause water pump failure and engine seizure, etc.
