6.4L blowing out radiator

I assume i'm at the correct forum location for these 6.4L's. Redirect me moderators if i'm not. This 08 F350 has blown out 2 radiators & International is most likely coming out next week to investigate. Has alot of water & oil deposits in the intercooler. They told me to check the fitting going from the frt. cover to the heater core for restriction. Customer did state that it got hot on the 2nd time in but not on the 1st trip in. Only set a egr cooler temp low voltage code from coolant system getting very low on coolant & not cooling egr properly. Tested radiator cap & does vent properly. wondering if anyone has run across an concern for this. The eng. runs normal w/ no smoking. no missfires or codes this time in, just a P1000 from the last time he was in which was less than a week. Customer is very mad & has contacted ford about this concern.Any info would be helpful.thought i would get a jump on this before international came out. I have all the freeze frame data recorded for this.

Seems like I read an article about these 6.4's having high volume water pumps. Maybe something to do with this???

were you pertaining to your 2001 trk.? i was pertaining to the 6.4L's. the reflashes for your trk. has diminished some what. the only time i reflash one of the earlier models is when one comes in w/ a chip or programmer & they want be to reflash it back to its original configurations. the 6.4L's. have only one so far for the flames shooting out the exh.

It has something to do w/ the fuel strategy & timing lowing the fuel pressure during the particulate filter cleaning stratigy. I'll have to do some more research though. It has something to do w/ fuel control, that much i do know.
