My 1993 gmc sierra 4x4 4.3L v6 won't stop whining and I don't know what I can do to fix that

Asked by 15004x4 May 24, 2015 at 08:04 PM about the 1993 GMC Sierra C/K 1500

Question type: Maintenance & Repair

My truck has been doing a whining sound
for quite a while now and everyone was
telling me that my p/s pump was getting
ready to quit so I bought a new one and
replaced it and it's still doing the same
whining noise as before as though I didn't
do a single thing to it. What else could
cause that noise?

It has a steering box. Take the belt off and start it up. Is the noise still there? Don't do this more than a few minutes as your water pump won't be turning
