Nissan Altima Serpentine Belt
I have a 2002 Nissan Altima, 2.5L (4-cylinder) engine and would like information on how to release the serpentine belt tensioner and replace the belt. Also, please let me know what special tools (if any) will be required for peforming this service.

RE: Nissan Altima Serpentine Belt
Here are some instructions and picture. No special tools needed.

Remove front RH engine side cover.

With box wrench, and while securely holding the hexagonal part in pulley center of automatic tensioner, move the wrench handle in the direction of arrow (loosening direction of tensioner). CAUTION: Avoid placing hand in a location where pinching may occur if the holding tool accidentally comes off.
Insert a rod approximately 6 mm (0.24 inch) in diameter through the rear of engine into holding boss to fix tensioner pulley.
Leave tensioner pulley arm locked until belt is installed again.
Loosen auxiliary drive belt from water pump pulley in sequence, and remove it.
