Ford 6.4 Radiator Failure
6.4 Radiator Failure Possible cause. Pat
Forum Discussion
Bill Hewitt raises (ha ha) an interesting point.
It was EXACTLY in model year 2008, coinciding with the introduction of the 6.4L, that Ford changed the radiator support structure, and the front fender support structure, and the lower front frame.
Every structural element surrounding and supporting the radiator in the 6.4L was all new, and very different from the 10 years of Super Duty production that preceded.
The image that best illustrates the structural changes are in the Ford Super Duty brochure for 2008. I have the paper version, but I could not find a digital version online to share, but I did find some images of the cut away sled that Ford paraded around to the press, with the new structural elements painted in bold yellow and red colors, by Ford, to show the press junket the changes.
Here are some examples:
The yellow and red elements are all new. Notice the deepened front fame horns that were lowered to eliminate the Blocker Beam.
It is not unreasonable to suspect that the increase in radiator failures from 2008 forward... failures that did not occur in trucks built from 1998 through 2007... could be related to these structural changes to the front end.
I'd post this comment under Bill's video, but I do not have an account.
