In this video I show you how to install a serpentine (fan, pulley, accessories) belt on a Nissan VQ40DE 4.0 six cylinder engine. This process also applies to the Nissan Xterra and Pathfinder. You only need to have a good socket set with a 3/8" ratchet end. Having a serpentine belt tool will make it easier to do. The whole installation only takes about fifteen minutes to complete. The belt cost me around $40.
