Anything Dorman is JUNK
I didn't think dorman made one for the 6.4? either way the 6.0 ones are horrible!! we recently finished one that needed 3800 in repairs from failed dorman cooler installed by the ford dealer!!!! I think we have pulled at least 10 of them this year because the gaskets turned to green mushStick with the ford cooler. Dorman is what you use when you can't get anything else. They are not horrible but this is the kind of thing you only want to do once. The ford kit is not that expansive if you order it from tousley (where i got mine).
:whs: there are a few ford dealers selling parts . that look like 10% over cost.Yea ebay is great for new in box parts. Just make sure they are new, unopened, oem and from a seller with a good rep. Just do a search for the ford part number.
