SOURCE: crankshaft and camshaft sensors location in nissan altima 2003

You are incorrect sir. There is a very good Youtube video showing you exactly where it is that is how I changed mine. The Crankshaft is located behind the engine block below and around from the cam sensor which is easly spotted looking at the engine. The crankshaft is in a difficult spot but once you figure out where it is it's easy...ish hope this helps

First of all, you'll have to clarify which belt it is you're talking about. Is it a SERPENTINE drive belt or a Timing belt? Two totally different belts.
If its a timing belt, you're in luck as Nissan Altimas have timing chains on the engines which shouldn't need replacing for at the very least 100,000 miles. If you're talking about the serpentine drive belt on the other hand, there's really only one way it can go over the pulleys. One side of the belt it grooved, and one side is smooth. There's only one way it can go over all of the pulleys while having the grooved face sitting on grooved pulley surfaces,... should be really easy to figure out.
