So i drove my 2019 straight to the dealership when had loss of power bogging and dash lighting up... seen its the tube sensor thing going to clutch fa

I forgot to add- Backorder = High failure rate & High Demand.

I still get the covid and supply chain excuses for backordered parts.

And you think all is as before covid?

There is line of demarcation, but covid had nothing to do with it.

Alternate universes that only overlap on the 5G Ranger Forum I guess.

I hadn't broken two hoses within a year but patched the same one twice. Both times it broke on the end away from the fan.
Yesterday I patched it to (hopefully) make it to the auto parts store.
My thoughts were to just replace the old hose with something stronger.

I asked about some reinforced rubber hose at NAPA and the guy had some cloth reinforced stuff.
He called it multipurpose hose and said some NAPA stores have it in black and some stores have it in red. I
The 3/8" looked a bit small, so I bought a piece of 3/8" and a piece of 1/2".
The fabric reinforcement looked a lot heavier on the 1/2", but 3/8" ended up matching the old hose.
(The 1/2" didn't fit tight on either end so wasn't used.)

When I got home and started to do the repair, my patch from yesterday had already come loose.
(I had wrapped a strip of Gorilla Duct tape around the split, then covered with my extra wide hose clamp. The old hose was just too brittle on that end.)

I re-used the stout crimp hose clamp down at the fan sensor, and used my wide hose clamp at the top.
I tried to get some fancy zip ties like the factory ones that carry the wire harness piggyback, but couldn't find any and just used regular zip ties.

This hose should hold a few years, it's built much better than the soft rubber factory hose.

Thanks for the write up sandog. Going to go this route myself after my hose deteriorated and snapped at passenger side connection

I am still highly curious if this is a band-aid fix, I was hoping that owners who were getting it replaced by the dealer would get or able to get a (DETAILED) reason for why this fails this way.
I have a theory but zero proof.
For me, I find it hard to believe that this is normal wear and breaking, especially one above with 2,700 miles on it.
Something in that clutch is causing too much force being applied to the support hose.

The reason why, I feel something is amiss, is on my 22, the module barely moves with engine running and I carefully reached down and held it and also moved it in the opposite direction of fan rotation expecting it to resist me. It did not.
Basically, the point is, there is no way enough force is being applied to break the hose on a working clutch.

So, I would monitor closely after doing this to ensure it holds.

I had no interest in having the dealer replace the hose with the same inferior rubber that failed in the first place.
Surely (Shirley ?) Ford could have chosen a more suitable material for the hose.

Interestingly, most failures of the hose seem to be at the same end, the end away from the fan.
There might be an even stronger alternative to the cloth fiber reinforced hose I used, but anything is an improvement over the factory material.

I am with you on this. IMO, the broken hose is a victim a defective fan clutch. Maybe the bearings are failing, then ripping the hose and harness. To me, it looks like the hose is only there to keep the harness away from the fan and belts. If the clutch or bearings are the culprit, a stiffer hose isn't going to save the harness.

If my hose failure is being caused by a failing fan clutch, then my "band aid" won't last very long.
We'll see, but I'd bet that the new hose will last much longer than the 2 years the factory part lasted.

I would agree with these statements if the hose had a clean break but the hose is literally disintegrating in my fingers. This leads me to believe it’s either poor manufacturing or wrong material for the job.

Let me know what store that is, I wanna get me some of those hoes !

While I've enjoyed the 9 pages of highly technical discussion (which mostly went over my head),
I believe that some tend to overthink this.
It's a crap piece of rubber that deteriorates quickly, it's possible that it's just that simple.
Replace the hose with something better, and check it's condition once in a while.

 

[MarioCart]

rubber always degrades over time.
there's probably a whole bunch of rubber compounds better suited for this location than what Ford chose.
I am sure Ford did their due diligence on selecting a rubber, but they fell short in their findings for whatever reason.
When you attend a dealership for service, including a multipoint inspection, they should be checking this part, as it falls under the "belts and hoses" portion.
If they aren't finding it and reporting the high number of failed or deteriorated parts, then Ford isn't getting the full picture of their poor selection.
