To release tension on the Serpentine belt on a 2001 pathfinder you need the following tools:

10mm open wrench, 12mm socket, long socket extension, socket breaker bar, 14mm socket.

Start from above the engine, loosen the fan hood from radiator, use 10mm to loosen the fan from the pulley, ( to remove the belts later), leave up against the radiator but out of your way. Remove the plastic skid plate from under the front bumper. Use the 14mm & breaker bar to loosen the nut on the tensioning pulley, then look at back of pulley- you will see a threaded bolt that is operated with a 12mm wrench on the bolt. Now do the same to the other pulley on the other side of the engine. All tension is released from below the engine.By loosening this bolt you will relieve the tension on the pulley to allow changing of the Serpentine belt. Reverse the procedure after replacing the belts. Check for proper tension and monitoir that nuts on fan are tightened correctly.
