In this short video, I will explain to you what inverter coolant means in the Sonata Hybrid. This is the vehicle with two separate cooling lines that work for the engine and high-voltage battery systems. It’s not that hard to locate the tanks and to understand what tank holds what coolant.

Please keep in mind that the two tanks will require different types of coolant if you need to top up or replace the fluid.
