★ Top Answer
The makers of the Hyundai Sonata Hybrid recommend using pentosin pentofrost a2 hot phosphate Asian concentrate antifreeze as the type of HEV fluid for your car. This fluid is crucial for cooling the electronic motors and components in hybrid cars. Unlike engine coolant, this HEV fluid is specifically designed to prevent rust in the cooling system and to lower the freezing point. Different coolants are formulated with varying ingredients due to the diverse metals used in engine blocks, which necessitate different additives to prevent rust on the metal hoses. It's advisable to flush your cooling system every three to five years or every 30,000 miles to remove rust and debris, ensuring optimal engine cooling.

If it states that the coolant is "not used for direct cooling of the engine" but also mentions the coolant being changed to maintain its cooling efficiency, does this mean the engine is cooled indirectly? Is the engine air-cooled instead? Also, what exactly is "direct cooling"? Thank you.
