This isn't my idea but had learned about this from another Forum. There is nothing about this 'possible' fix to our water pumps going out a low mileage on this Forum so i thought i would share this with you all. My water pump is still good after 5 years and 22,000 miles, but have read on a lot of Mustang Forums about several 3.7L V-6 water pumps going out at pretty low mileage. When the 'dealer' changes the water pump, they also replace the degas (overflow) hose with one that has a 'check valve'. Why? I don't know, some people 'thinks' air is getting sucked in with coolant, causing the water pump bearings to get hotter and causing failure after time passes.

I replace my degas hose with the one the dealers are using when they change water pumps on our V-6's. It was only $25 so i figured it couldn't hurt. Could this new hose with the 'check valve' make my water pump last longer? I don't know Here are some pictures of the old and new hose. Sorry this Thread is longer than i had planned

The part number is ER3Z-8276-A

 

Thanks for the heads up! this is the first that I've read about this potential issue. its definitely worth the investment if it means peace of mind and saving your water pump!

 

Anytime. I'm a member on 8 Mustang Forums. This Forum has the least V-6 activity of any of the other Forums i'm on but, "this (The Mustang Source) is my favorite Forum". I like the people on here the most.

I went on a 150 mile drive yesterday and didn't see anything different on the temperature of my engine so, thats a good thing

 

There's other mustang forums?

 

Yeah, I've tinkered and stared at the gauges a bit as well. the temperature has been pretty consistent through the seasons but, that doesn't mean there isn't any extra stress (extra wear due to air) going on in the background. I'm definitely going to pick this up. I'm due for a new air filter. I'll pick this up at the same time!


lmao!

 

Thanks again for the tip, David! I got my part ordered. dealer will have it tomorrow and it was $39 before Taxes here! not too bad for peace of mind.

 

The fiancee's 2012 6'er had 133k miles on the clock when we traded her in a few weeks ago. She was eating a small amount of coolant (maybe a cup every 10k miles)... I wonder if the water pump was the cause.

 

Picked it up! This must hold true, this new hose has the check valve built in. Hoping to get this done Saturday afternoon

 

Excellent information! What is the procedure for install is this going to leak out everywhere?

 

+1^ Just ordered the part, also curious about install.

 

I say...Snake Oil Sorry This is just my opion only.
It's just a hose with a check valve tha allows fulid to flow in one direction only. Thats all a check valve dose. Now if it was an air eliminator valve, that would be a different story.
I cant see any benifits to a check valve on the overflow tank. A check valve is a moveable part that can stop working and stop the flow of coolant all together.
Not for me at all.

 

Maybe so. Why is it when a dealer changes the water pump under warranty, the hose is changed to this new one with a check valve on the v6's. Thats the mystery of the new hose

 

I did lose a little coolant when i changed mine. Should have had a short hose with a screw in it to plug the hole while i got the screw on hose clamps ready on the new hose. Some people are using the factory hose clamps but i had a couple of screw on hose clamps laying around so i used them

Hope this helps.

 

How exactly did you do the install. Did you disconnect from the engine first or the overflow tank? Where would you have placed the short hose with the screw? Just trying to picture the procedure you used.

 

If you do the 'engine' end of the hose first then the overflow tank second you shouldn't lose any coolant. I did it backwards

 

LOL!!! This is the Forum i'm on where i learned about the hose

 

Perfect, thanks for the feedback!



Yeah, I had a feelin'.

 

I didn't buy this hose because of the check valve. I only really noticed it had a check valve once I got it in my hands. I bought it because of the different bends in the hose. my warranty will be up really really soon and would very much prefer to spend $40 and do some PM and have the peace of mind that its running as best as it could be.

 

Is this something most dealerships have on hand?
