This diagram from All Data is correct.
The main bolt that holds the pump on is 14mm and you need to loosen it about 6-7 turns out. You can do that through one of the two holes in the pulley. I cut the old belt so I could hand turn the pulley and line up the hole with this main bolt. BTW, I found all of this easier when I took out the battery, that will provide more working room.
The adjuster bolt is below the pump and is a 12mm bolt. You loosen it to push the pump closer to the engine in order to get the belt on, then tighten it to pull the pump away from the engine to tighten the belt. This bolt head goes into the engine, so your socket should be perpendicular to the direction of the truck. The main bolt mentioned above is aligned with the truck, so standing on the passenger side, you can use your right hand to push down on the ratchet to loosen the bolt.
