Based off the circled picture the hose in question is number 13

On further examination of my car I think you are right. I just ordered the hose for $22 shipped. I am hoping it has the valve and will post when it is received. Sorry for the confusion.

Maybe this will help. This is a screen shot of the TSB info the dealer uses.

^ That clears it up! Good thing its the cheaper part.

Now, can swapping out the hose be accomplished without draining much coolant?

It's basically just a vent/over flow tube from the looks of it. Do it with a cold motor and you should lose nothing. Someone correct me if I'm wrong.

^ That was my thinking, but then the very design of the hose (without checkvalve) would encourage air to be pulled into the pump...weird.

I would assume that since the pump end is the lowest, that would be subject to the most loss.
I believe I would connect the new hose to the expansion tank first and then to the water pump last. The connection to the pump should be fairly fast to minimize loss of fluid. Another person to put their finger on the open connection may come in handy.;)

This looks a little scary. I am glad I stumbled up on this thread. I am going to go and check this hose on my car today.

I guess I'm lucky that my late-2012 build's water pump hasn't given up the ghost yet... but don't want to push my luck.

My June 2011 build 2012 has no leaks either. That is the question? Why does the hose cause pump failure on some but not others? My replacement hose is coming on Friday. Should I stop driving it until it arrives? Not hardly. It's gone nearly 37,000 miles without a backflow valve a few more won't matter. At least if the water pump does fail they wont' be able to say it was the hose that did it and that's not covered.

I just received my hose and it has the backflow valve. It took 15 minutes to install mostly because of those goofy clips Ford uses. The old hose was full of air and no coolant was lost in the install. I would say it was worth the $22 but then my water pump will start leaking next week so I won't.

^ Thanks! Thinking I might upgrade to some normal hose clamps when I upgrade.

Yea, I wish I just got a couple of stainless clamps too but now that the spring ones are on I don't want to mess with them again. I think it is worthwhile upgrade, hoses need replacing anyway and keeping air out of the waterpump is a good thing.

Agreed. But the worst have to be tower clamps. My dad and I have exorcized those from our 69 Camaro resto.

Oetiker clamp (those are the ones with two ears that you have to crimp)

^ I stand corrected. Those win the prize for the worst.
