HEAD GASKET REPLACEMENT

1991 GMC C2500 • V8 2WD Automatic • 180,000 miles

I have a 91 GMC Sierra, working on new head gaskets. 5.7 350cu small block.
the issue is, on the right side of the engine I need to take off the alternator bracket, which also houses the power steering pump. Now, on the front of this bracket is a wheel tthat the serpentine belt spins on. That wheel, how do I remove it?

Are you refering to an idler pulley? If so, remove the pulley and you will then have access to the retaining bolts.
