It fixed itself after I put some miles on it. Must've had air in the system, Ive been keeping an eye on the fluid levels

I have a 2000 M1123 with the built in PS reservoir, not the remote. The PS level is right on the cold mark in the morning. It seems whine noticeable.. Almost obnoxious. Maybe it will go away with time or should I open the PS cap and turn the wheels left and right to see if there is any air trapped somewhere??? Definitely a noticeable whining sound.

Any chance it could be the Cadillac valve gremlins trying to get out?

Will the Cadillac valve get noisy if it's unhappy or dying?

Most, when fan clutch is disengaged have a high pitched ultrasonic sound that can be conducted to it's mount, amplified by the foot well shelf...
Intermittent detection due to fan cycling on or off.

Wonder if I could put a 1/4" rubber pad between the Cadillac valve and the aluminum body panel if it would quiet things down???

Get a 6 1/8” long piece of rubber 2” wide and wrap it. I was amazed at the difference.

Something like a strip of inner tube?

I used a thicker rubber from another project but inner tube will work but probably 6” long.

Before going through all the trouble make sure it is the Cadillac valve, the "noise" will change between the fan running and not, you can simply unplug the wires from the valve to activate the fan, if the noise stays the same it is not the valve.

It's not the fan engaging... I know what that sound is. This is a whining sound. Not a serpentine belt sound, either. Slightly higher frequency sound. The Cadillac valve is working OK... Like CAMO said it may be making a high frequency/ultrasonic sound that insulating may help dampen.

If the cadillac valve is making noise it will change when the valve turns on the fan, the noise will not stay the same is what I am trying to say.

A popular joke in the C141 community goes like this:
What's the difference between the C5 crew members and the C5 engines?
The engines stop whining when they block in.
Is there any possibility you're hearing the turbo?

Just make sure your fluid is topped of and give it a little time, it sometimes takes awhile to get all the entrained air out of the fluid.
Does it change when you steer the truck?

I'll have to drive it again and pay attention as to where it is or if it changes at all. Right I think it's all the time, but I'll focus on various driving conditions.
