Need a quick opinion….

Well it's great you checked in with us, and I am sorry if I scared you, but better safe than sorry.

You were right to bring it up James - the first thing I thought of was how the hose that holds the harness out of the way has failed for others and shredded the harness. Not as devastating as that other case involving the belt tensioner that exploded, but still a journey-ending experience.

@underwhelmed - to give you some additional peace of mind, you might want to make sure that noise isn’t anything in that hose/harness “assembly”, including nylon zip-ties, rubbing against anything as it rotates.

I’d hate to see you miss out on some brookies. I don’t fish but I know how much those who do really like it. Have a safe trip.

This time it’s a wild pig hunt ?

What? Didn’t you see Old Yeller? Be careful.

I'm still going to follow this thread.
For some reason in a few days I feel we are going to hear about a grenaded transmission.

???????????

hope you have a safe trip!
i would see if the sound changes. like cold start wait for it to idle down and be at operating temp and listen for the noise or change to the noises frequency etc. also see if it changes with rpms.

I might get it checked just for piece of mind. I installed the foam engine cover an I thought it helped quiet things down a lot. When I ordered my bronco I figured I'd have to put a cover on it too to fight the noise. Turns out the bronco comes with a foam cover over the pump it's self, looks like the ranger cover is hard plastic. Here's the foam one:

I wonder if there will be an electric fan conversion for the Ranger at some point in the future. It was popular in some circles back in the day for eliminating parasitic drag on the engine.

parsitic drag

Thats the pet name I call my wife , strange to see it here in print ...

Yes, the sound bite you posted appears to be just the HPFP noise, louder at start up and once the pressure equalizes it quiets down, within a minute or so after start up.
No engine cover = equals the louder it is, no foam cover absorbing and muffling the sound.

Now, the area and part you are describing is the fan clutch, the black electronic module on the back side of the Fan-Clutch is designed to float and it is not a rigid secure mount.
With engine off, you can rock it side to side, however with engine running it should pretty much be stationary.
This is the unresolved theory on the Fan Clutch failure, what precisely is causing the hose to break, is it degradation of the hose or is it the Fan Clutch putting too much stress on the support hose.
Or a combination of both.

Either way, per the service manuals there is zero guidance on the Fan Clutch failures expect for Code Only troubleshoot.
One way to tell for one that is Failing is to watch the operation and note how much rotational force is being applied to that hose.
This one failure item has sparked my interest and would love to get my hands on a failed clutch just to see what is actually happening or a documented dealer tech explanation as to why the intended or unintended outcome for a full fan clutch failure result is the hose and wiring harness being ripped out.
I have a hunch it is a bearing and or raceway causing the electronic module to hang and grab and is being forced in the direction of fan rotation, the support hose is only a support it is not designed to handle a great force being applied.

So, if my hunch is correct replacement of the hose is just a band-aid fix to the actual issue of a failing (expensive) fan clutch.
The reasoning for my hunch is that when I watch my fan clutch, I see zero rotation force on the module. It stays stationary,
The problem is I have not seen any failing fan clutches to do a side-by-side comparison and note any difference between them.
Is a good one different from one that has had the hose actually break?

I am in agreement with you. IMO, the hose is there only to keep the harness free and clear.
One way to verify this would be to disconnect the hose and harness, then see if the assembly can be rotated by hand. My guess is it can't.
Any volunteers?

If I understand your 'hunch' is that under normal operating conditions, the stock set up could be just fine, but when the clutch itself fails, it's gonna wipe it all out.

Agreed. IMO, if that happens, no particular hose or metal bracket will prevent it.

I wonder if there will be an electric fan conversion for the Ranger at some point in the future. It was popular in some circles back in the day for eliminating parasitic drag on the engine.

Maybe, but electric fans will never draw the amount of air as the stock fan. I wouldn't want to risk overheating.

That is certainly correct, my shrouded clutch fan cooled better than the electric type with no shroud but it was a track car. I don't know if the Ranger would have an overheating problem.

I don't hear anything other than direct fuel injection pump and injector noise in the video. Based on that, I would say no abnormal noise heard.

Really? Mine doesn't sound like that. I get normal fan and engine noise. No noisy clacking/scraping sounds like I heard in that video. I'd have it looked at.

Just normal high pressure injector and pump sounds are all I hear in the video. Those sounds are normal for every high pressure direct injection engine I've ever encountered. I've driven a few rental car Mustangs and Explorers with the 2.3 and they all sounded the same to me.

You could be right. Quality of the video perhaps. Just sounds clacky-screechy to me.

It does sound a bit extra, but I also recorded a video of mine in the past. The video recording playback always seemed to sound a bit extra noisy when compared to in person. Something with how phones capture sounds for videos I guess. I'm assuming yhat is the case with the OP's video.
