Check for a flat washer at the back of the pulley that holds the bearing carrier away from the mounting bracket. If there is no carrier that the bearing is on as it may fit directly onto the shaft then check for a spacer that goes against the inner part of the bearing and the mounting bracket that positions the pulley in line with the belt.

How to tighten belt on 2004 nissan quest


Best to remove the front passenger side wheel. Then snap out the clips that are holding the plastic cover towards the front. Now it will expose the belt area. Loosen the locking nut of the tensioner(idler) pulley located to the right of the Crankshaft Pulley. Crankshaft pulley is the one that handles both belts (alternator and the power sterring pump). Right to that next to it, upwards is the idler pulley. You will find the alternator pulley to the right of that further up. Open the hood of the van and locate the adjusting nut behind the alternator on the idler pulley from top and loosen that as well. Once both these are loosened, belt will loosen and will be easy to remove. Now replace it with the new belt the same way it was wrapped. Go over the crankshaft pulley; under the A/C compressor pulley; over the alternator pulley; under the idler pulley. tighten the adjusting nut from the top through the hood until the play on the belt (when pressed in) is less than 1 inch. Now lock the tensioner pulley by tightening the locking nut. Start and run the car for 15 mins to see if everything is ok.
