Sudden loss of power steering, power brakes, air conditioning and the battery light stays on. However the truck is still drivable.

Did the serpentine belt snap?

Did the serpentine belt snap?

Thanks the belt did snap, went to replace it and found the Power Steering Pump Mounting Bracket cracked in half. Looks easy to replace, just a couple of bolts correct?

You shouldn't have any trouble. Be sure to replace the tensioner pulley, before you install the new serpentine belt. Afterwards, empty and refill the power steering reservoir with Mobil 1 Synthetic Multi-Vehicle ATF.
