Can anyone identify this noise?

It's coming from just behind the radiator. You can really hear it when I reduce the throttle.
Thanks!

Hey there,

Did you check to see if the fan is nicking the radiator overflow tube?

I hope that's it, because it's easy to fix.

I'm pretty sure it's not. I made sure the overflow tube is well secured, and it showed no damage.

Hi,
If your fan belt is too long, so the fan is up too high, the fan tips could be hitting in the top of the shroud, or whatever is up there. It can't be seen up under the hood, without a light probably.
The new belts I buy at Case IH make the fan shaft a little below half way up the slots in the engine front cover.
It might be noisy running belts, hard to tell without being there.
The fan hub needs oiling too, the instructions are in the owner's manual. :)

It sounds like a very light hit, such as a wire (left head light wire falling down, maybe hitting belt, bearing needing oiled are getting worn either in fan or generator. Another possibility is very tip end of fan blade barely contacting shroud.
If you are not part of the solution,
you are part of the problem!!!

The Fan is hitting the shroud. Bend it out of the way
