I would be surprised if many of us have the hose with the backflow valve installed at the factory. The TSB effects all 3.7's from 2011-14.
You are right there is no sleeve on the hose that ponie got but the hose is the same and has the backflow valve. I believe Ford has the part numbers for the 2 hoses switched in their online database. If you search the part # on ponie's invoice it looks totally different and is in the wrong place on the diagram.

Checked last night, and no check-valve in my factory hose! Time for an upgrade...are we collectively sure of the part number?

Iguana's number is the other hose that goes to the expansion tank....my early 2012 build does NOT have the check valve.

I certainly wish you were right since there is a $30 difference in the price of the 2 hoses, but if you look at the diagrams the one I posted is correct. I also can't see how the hose with the backflow valve would be the cheaper one. Look at the pic below. Is the hose in question #12 or #13? The part # on ponies invoice is for #13 in the diagram.

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 wouldn't think you'd lose much coolant.

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.

Installed mine this wknd on a cold engine. I lost just a bit of fluid that prob was trapped in the hose, none came out while the hose was off. I just used a med. size channel lock pliers it only took 1 or 2 minutes. The check valve does allow fluid/air to go from the engine to the overflow tank. IDK if it'll do any good but having seen several folks online have their water pump go and having Ford suggest this hose as a replacement I'll recommend everyone do this as a preventative measure. A new hose costs less than $25 and it takes less than 5 minutes. I can't understand why having a check valve in the degassing line would help (although I understand what it does) if anyone has a theory let me know.

Thx to all that posted up info on this.

I am sorry to say that there does seem to be NO measurable HP improvement on the butt dyno.

As info, my 14 v6 vert was built 06/04/14. (of course the engine may have been assembled earlier) It does NOT have the revised hose. Thanks for the info & part, & TSB #. I'll be ordering and changing it myself.

The overflow hose is ER3Z-8276-A. I bought it for $11.78 from Tasca.

This thread was timely. During tire rebalancing last week, the lube tech found a coolant leak. Just took my 2012 (51,000 mileage) car in this AM, and the service advisor called me about an hour ago with the bad news. Same issue as the TSB noted. Will need a new water pump and degas hose (at $450). Won't be covered under warranty because the non-powertrain related check valve-less hose was the "casual part" that took out the pump. Called Ford corp, CSR apologized but said there were no programs or remedies to get pump covered. The service advisor also noted that this issue has created a lot of unhappy customers they've had to deal with and wishes Ford corp would do a recall to get the parts covered. So why is the water pump considered part of the powertrain (and warranted) and the degas hose isn't? Probably a Ford bean-counter decision!

Yep, exactly what happened to me. Hose is the "causal part". Stupid loophole. I don't know how ponie1992 got it covered. Maybe you can try different dealers and see if one will be as nice as his was.

In the meantime, if you get the gurgling sound, top off the coolant and burp the system. Just a band-aid until you get the leak fixed, but will prevent you from running hot or causing more damage by having air run through your system.

Hoses and other rubber parts are not covered because they are subject to "normal wear and tear" like brake pads. Why that hose is considered the "causal part" is what is suspect. The hose did not fail, it was defective from the start because it was missing the check valve. Why that is not Fords fault is beyond me. I am glad I got the new hose, now if the pump fails at less than 50,000 miles they have no excuse.
