Loosen the tensioner pulley. When the tensioner pulley is loose the belt will come off. Put the new belt on and tighten the tensioner pulley.

If the belt only drives the ac compressor, loosen the compressor mounting bolts to let pressure off of the belt. Remove the belt and put on the new one. Pull the compressor to the side and put enough pressure to tension the belt as you tighten the bolts.

The "serpentine" belt does not serpentine. It runs the alternator and water pump only. To change you will need to work from underneath. If you have AC remove the AC belt by loosing the AC adjuster bolt and sliding the compressor over. If you have to take the AC belt off better change it, they are cheap and you don't want to do this again for a long time. Loosen the alternator adjuster pinch bolt. Some Fireos has a adjuster screw, some don't Move the alternator to loosen belt. Remove and install new. Tension belt to recommended tension on packaging on new belt. Reinstall AC belt, use the tension instructions on the package.

You actually expect to get an answer. Would that be a Ford, Chevy, GMC, Dodge, Toyota, Nissan, or any other of the makes of trucks out there?

The ac belt will need to have the tensioner to take the belt off. The serpentine belt is in front of the compressor belt and will have to be removed first.
