Holly. What fluid you using in the pump.? It doesn’t take long for bubbles to go. There might always be a few bubbles. The belt is your problem. Which piullies you go with ? V belt. 6 or 8 rib ?

I just replaced the fan clutch and my issue is exactly the same. I cleaned all the pulleys and replaced the belt for a 3rd time and still getting the metallic squeal at 2300 rpm or higher.

Nothing is leaking and I have triple checked all the fittings and connections. Could my steering box be allowing air in somehow?

I am at a loss on this one!

My story same issue in this order, soap on pulley, belt dressing, sent power steering pump out for rebuild and tried 3 different belts all cog. Bought a repro belt from Quanta Products, sold by our sponsor and problem solved. Yes, new fan clutch too. The repro one with holes not the cheesy one.

TA - did you fix this?
I am also fighting the bubbles.
I also have a sequel at 2500 - going straight.
All new system. I went with their serpentine system.

Yes finally, it took 3 pumps to get one that would bleed properly and run quiet.

if this noise shows up at 2300 RPM, you dont need to drive the car, just push the throttle by hand until it makes the noise at 2300rpm, then try & listen for where the noise is coming from to narrow it down. if you have a helper they can push the throttle while you listen around for the noise & even use a stethascope or long screw driver to put the end on each item like alt, p/s, water pump & hold the end to your ear, carefully.

as mentioned you can remove 1 belt at a time to see if the noise stops at 2300 rpm, or a short drive if the car needs to be moving for some reason to make the noise, but if its rpm specific you dont need to drive the car.

also just an FYI, you didnt need to buy a new fan/clutch, (if thats what you did) could have just removed the fan & bolted the pulley down tight, then hit the 2300rpm & see if the noise is gone or changes.

hops you can track it down!

Glad the OP got his issue fixed. Just to contribute another cause for anyone reading this thread, several years ago I chased a "chirping" belt on a Tahoe with a 5.3. Replaced several belts and idler pullies before I noticed the PS pulley (which I had never removed or worked on) was out on the shaft about 1/4", making it not line up with the water pump pulley. The belt was slipping forward as it rolled across the water pump pulley, causing the chirp. (My clue should have been the letters wearing off the back side of the belt in just a few weeks after installing it.)

I used a pulley installation tool to run the pulley all the way in on the shaft and the chirp went away for good.

Dodge Trucks with the 318 and 360 were famous for belt chirping and the PS pulley not lining up properly. Usually took a Straight Edge to be sure the belt was straight. One tell tale sign was the worn area on the WP pulley would be wider than the belt.

Have you squrted the fan belt yet? I use water applied with a garden hose. If thats too messy , a squirt bottle will do. Squeal will go away instant ly and return as the belt driys out.
