How do you replace the drive belt on a 2000 Nissan Altima?

Answer 1

There are two belts on the 2000 Altima, the A/C compressor belt and the main belt. Remove the A/C belt first by loosening the nut in the middle of the idler pulley (the pulley below the compressor) and then loosening the tension bolt on the bottom of the idler pulley until enough slack is in the belt to pull it off. Remove the main belt by loosening the alternator which acts as an adjustable tensioner. Loosen the top and bottom bolts first then lossen the tension bolt until there is enough slack to remove the belt. To install new belts follow these instructions in reverse. Tighten the belts to about a 1/4" deflection and be sure to tighten all bolts. Notes: The lower dirt shield under the car may have to be removed first to gain access. Make sure to note the position of the belts through the pulleys before you remove the old ones. There may be a diagram under the hood of the belt route to use for a reference.
