6.0 and 6.4 radiator cap

[GoFastPadre]

I was at the stealership this morning having some work done and my service advisor tells me that the engineers at Ford have discovered the cure for the ongoing egr cooler problems. It is supposed to be the radiator cap. They have a new one that has the same psi reading, but it is supposed to build the pressure differently. The cap was only $15 bucks and if it saves the egr cooler great............ till I am out from under warranty and I delete the pice of crap Valve and all!!

I've heard of this about a month ago. Someone even posted the part number. If it works as advertised well worth the $15.

My truck had a train whistle noise and by getting the 08+ cap the nise has since went away. I think it is a good part for the money

Ya they gave me a new cap that takes more effort to click.

This doesn't make any sense to me...

Does anyone ever have coolant leak out their radiator cap? Mine comes out the overflow... as does every other one I've seen...

Mine puked one time out of the cap so I guess this would be a good item to buy.

What does the fixed cap look like? Mine has a white sticker with red lettering. Is this the new one?
