Filter for Coolant?

The cavitation problem was in the 7.3 i have one also where you have to add FW16 to the coolant now to the coolant filter one of the best moves you can make to clean the casting sand and other junk plus the big killer in the 6.0 is the Ford Gold crap coolant the silicates can't take the heat then fall out and plug the oil cooler the 6.4 should be the same. If you are out of warranty you should look into a flush and ELC coolant get a good set of gauges like the new Edge Insight to check deltas EOT-ECT the 6.0 max set by Ford 15* mine after a flush 3* it's all about heat. Here is the coolant filter.

Nope, this motor is not the same. A coolant filter is not so much needed on this motor. There is no issue with oil coolers being plugged or failing. Proper testing of the nitrates and changing at the recommended interval will be fine for this motor.
A filter for the coolant can be added if you desire but I see no reason for it.

Cavitation problems on the 6.4 show up primarily in the front cover of the engine / back of the coolant pump. Cavitation causes pinholes to develop here and allow coolant and oil to mix.
Regular coolant nitrite testing and VC-8 addition as needed is critical. The specified test intervals have been reduced and the testing is now specified for all maintenance schedules, not just the severe duty schedule. Given the low cost of the test strips and the ease of testing (sampling from the degas bottle is ok), I'd recommend testing at every fuel filter change (~10k intervals).
The front cover has also had a design change that seems intended to reduce cavitation issues. One of the techs posted pictures of a cavitated old style cover and the new style cover that it was replaced with. The new style cover had an extra tab of material added in the coolant flow path near where the cavitation damage showed on the old style cover. This tab would seem to be intended to modify the coolant flow and eliminate a low pressure area where cavitation is most likely to occur.
Cavitation has nothing to do with filtering of the coolant, so a filter would not have any effect on the cavitation issue.
