[me and my metro]

The 6.7l ford runs two complete and separate cooling systems. One is for the block, oil, heads and the hot side of the egr system, it runs at about 200 degrees. The second system runs at about 150 degrees, it cools the water to the charge air cooler, the cool side of the egr and the fuel system. It is complicated and not put together very well, we have 6 of these at work and I have replaced the primary radiators in 5 of these trucks. One truck twice in 125k miles. They do run well and are much less problems than the eight 6.4L fords we have. LOL the 6.4L makes the 6.0 look like a good engine.
