Understanding your vehicle's Inverter coolant and the importance of its maintenance
Hybrid and electric vehicles are equipped with an inverter that converts battery energy to the specification required for the electric motor. This component can generate high amounts of thermal energy that is absorbed by the inverter coolant and dissipated through a radiator. Over time, the inverter coolant loses its ability to transfer heat and resist freezing. It may even become corrosive. Coolant level should be regularly checked and it should be replaced periodically.
