Well, lo and behold, my truck problems have been put behind me and I took it back home today. Today it even made it all the way home to my garage so life is good. I've got two questions though for any Ford 6.4L owners. First, when I shut it down after driving for awhile, the radiator fan seems to free spin for a brief time after turning the key off and you can hear it spinning and winding down. It makes a rumbling noise as it does so. My 7.3 never did that. Is that unusual? Secondly, in the 7.3 you had to maintain an additive in the coolant which helped prevent cavitation internally. I don't see anything in the owners manual of the 6.4 about this. Is this no longer a requirement?
Thanks,
Pete
btw...... I sure do like the feel of the new truck. This is one quiet and smooth diesel.
