Flushing Anti-Freeze; Coolant & Hybrid Systems
My 2016 C-Max is 5 years old....which means, according to the Ford maintenance Schedule....the Engine Coolant and ...maybe if its separate...Hybrid Battery coolant needs to be flushed and replaced.
Vehicle has 14,000 Miles on it....I think Coolant losses its protection qualities by both Mileage (50,000 Recommended) and years...in my case again, vehicle is over 5 years old.
Here what is very perplexing...I called 3 Ford dealers, Flushing Engine Coolant and New Anti-Freeze
Managed to pull this from the workshop manual CD I have for my 2013. It does have the procedure for drain/fill/bleeding the hybrid coolant system. Also included the listed procedures for trans fluid drain and fill. So the procedures are there. It may be terminology throwing people for a loop. As noted, the inverter cooling system has nothing to do with the HVB cooling. So wouldn't be surprised if someone not familiar with the vehicle is unaware of the second cooling system or how to work on it.
