That is really a "Two party" question.
Caterpillar fit the water pump belt. This is the inner belt and runs just the water pump. Goes from crank pulley to water pump to idler pulley. It is an old fashion slack adjusting idler pulley.
Your chassis maker speced and fit the other engine accessories like alternator and dash A/C compressor and you will need to check with them for the proper belt (serpentine belt) and it's routing. It is on an automatic belt tensioner.
