[Solved] Mechanical Fan-like Sound While Idle/Accelerating

[BTomorama]

Anyone else with a 2.3L here this? Sound was not present up until recently and almost sounds like a fan or something else rotating, but nothing visible with the hood open and seems to come from upper part of engine.

Guages normal and no warning messages.

Update:
Found the issue and for me it was extremely easy fix.

A wiring harness gasket in the engine firewall had fallen out. Sound is normal, but with the open hole to the engine compartment made things sound badly.

The spot is on the drivers side in the firewall near close to the fender. Check that spot and if that gasket is in place and you still hear a noise, you should still bring it in.

I do! I was wondering if I should take my bronco to get looked at, or is it normal?

Definitely did not hear it the first two months of ownership, so I would schedule an appointment.

No offence but is it your Turbo? Some turbo cars make a lot of whooshing noises after things break in.

@Ford Motor Company can you please post findings here for the rest of us with 2.3L motors?

Definitely not the turbo. It has a rhythm too it, where the turbo is the whoosh you mentioned. Plus it happens at idle even at Park.

Might be helpful if you could post a picture of the area, and maybe circle the culperate.

Thanks for sharing this!

I'm having the same noise on my 2.3 manual transmission. It wasn't there a few days ago. I only have 400 mileage on it. No warning lights or anything just that noise started out of nowhere. Still looking for the area that gasket is in to see if its missing from the picture you uploaded. Its -5 here right now so I'm probably rushing and missing where that gasket is. Where did you get a replacement gasket? Or was yours just loose?

I believe the gasket the OP is talking about is the hole plug for the clutch linkage. He has an auto (I think) so he has the plug, you with a manual would not have this plug, must be something else.

Thank you! I just looked and yeah I definitely don't have this gasket! Definitely something else. I made a post about it but gonna take it to the dealership even though I don't have any warning lights or errors. Thanks again.
