so my 6.4 has a turbo pulling on another turbo that is pulling exhaust & blowing in top of cyclinders? i dont really understand 2 turbos in sequence. also how does the turbo/pump/ antifreeze cooling system work? is it just a fuel cooler?
Two turbos: you have a low pressure and a high pressure VGT. The two turbos in sequence are meant to get you power from low rpm to high rpm. That’s why they are set up the way they are. The radiator fluid is simply to cool the fuel cooler, and also the VGT (if you use the old VGT). The new VGT no longer uses coolant.
Lol! There doesn’t seem to videos of this taken apart… that I could find. Maybe they are out there, but there just didn’t seem to be much. Which is why I made this video. Plus, I found it to be very cool to see how it all works.
