2004 Toyota Prius Q&A
2004 Toyota Prius Question: What is Inverter Service? How will it improve performance?
It won't improve performance. It will increase the longevity of your car. The coolant used on the inverter is only effective for 2~3 years, and needs to be flushed. http://artsautomotive.com/publications/7-hybrid/116-prius-30k-service/ - TheWindBlows
