Where is the belt tensioner on a 2001 nissan pathfinder

SOURCE: How do I replace a serpentine belt for a 2001 nissan sentra.

Hi gj,

It's easy and you won't need a prybar.

• Get a 14mm or 9/16" socket and a long handled ratchet or breaker bar.
• For putting the belt on: Get the belt around all the pulleys except the A/C compressor or Alternator.
• The tensioner pulley is on a spring loaded arm. Get your socket on the center nut of this pulley.
• Slowly pull the ratchet toward the center of the engine. The pulley will pivot on the arm allowing you to get the belt on the final pulley.
  
• Slowly release the tension.
  
• You're done

Disconnect the battery - both positive and negative terminals and remove battery from holder (better access that way). From underneath - remove the plastic shield underneath the front of the car. It is held on by a few bolts. Remove the upper radiator hose (some coolant will drain out). Also free the cable from the support bracket on the top of the platic fan housing. There is an overflow hose that is also clipped to the fan housing unlcip the hose and move it out of the way. From underneath, push in on the clips and the lower half of the fan housing will come out of the bottom. From the top - remove the two bolts holding the upper part of the fan housing and you should be able to work it out from the top. You should now have better visibility and access to the alternator. Loosen the belt tensioner (from below) and remove the belt. There are two mounting bolts on the alternator, a long one through the alternator and a second on the "dog ear" of the alternator. Once the alternator is free - you can get at the battery cable post and the other wires. The wiring harness can be removed by pressing in on the locking clip. Most difficult is the wiring harness support bracket. A short 10mm wrench can get to it. The alternator is now free but will have to be manipulated forward so that it sits below the fan. Once there - you can reach down from the top, and pull the alternator into the larger gap between the fan blades. While rotating the fan, bring the alternator around with it to the top and it will come out. To reinstall -- do everything in reverse. I recommend replacing the belt so you don;t have to do this again.
