6.7 Cooling System

Can anyone explain the cooling system on the new 6.7 diesels? Specifically, why does it have 3 coolant reservoirs, each with their own cap? I checked the owners manual and, unless I missed something, all it says about checking coolant is to maintain it at the proper level in the reservoir; I guess that means all 3.

Should only be 2 reservoirs. There is a primary and secondary cooling system, each cooling a different group of components.

Go here and check out the 6.7 coffee table books. Tons of good information including the cooling system info.

You are correct, there are only two reservoirs for coolant. I can neither confirm nor deny that I might have been looking at the wrong thing.
