Question about 2002 Buick Regal

Change the serpentine belt on a 2000 Buick Regal

There is not enough clearance to get a socket wrench on the hex part of the tensioner due to the windshield washer reservoir being to very close to the tensioner. Do I remove the reservoir, get a special tool or what do I do to make this replacement? I need to put a wrench on the tensioner to release the old belt and provide clearance for the new belt when it is installed. Thanks.

How to replace serpentine belt to alternator

You'd better hope you have a belt routing picture under the hood. Usually the belt is released at the tensioner pulley, which is spring loaded to keep the belt tight. The pulley is unloaded by using a 3/8 long handled socket wrench. Find the square hole.

How do i remove the drive belt on a 2006 Toyota Solara?

Serpentine belt replacement is not complicated and requires only one tool. Find the tension pulley located at the bottom of the motor. This pulley is attached to a very strong spring and holds the belt tight against the pulleys through its serpentine route around the engine. Use a socket wrench with a matching socket the same size as the hex head bolt in the center of the tension pulley. Attach the socket and set the direction to tighten the same direction the spring action allows the pulley to move. Turn the wrench handle, the pulley moves and the tension on the belt slackens. Take the belt off the pulley and let it hang. 
To install the new belt Once the belt is around the pulleys allow it to hang freely at the bottom of the engine. Again, use the socket wrench to turn the tension pulley far enough so the belt can be wrapped around the pulley. Once the belt is around the tension pulley, release the socket wrench and allow the tension pulley to take up the slack. 
Good Luck!!

How do you change the serpentine belt

ALL serpentine belts have a tension pulley which holds the belt tight to the various equipment it turns (water pump, alternator, a/c compressor, etc). Find the one spot where the belt goes over a component that has nothing connected to it, and you have found the belt tensioner. The tensioner is designer with a nut on the face of it so that you can put a socket wrench on it; by 'unscrewing' the socket wrench, you should be able to release the tension on the belt - it will take some pressure to release. Once you have tested this, you can pull onthe socket wrench and remove the belt; replace it witha new one and take off the socket wrench. Make SURE you have the correct belt and be careful with the socket wrench; it takes lots of pressure to keep the belt tight.

How do I change the Serpentine belt on a 2001 Buick Regal

You have to turn the tensioner pulley clockwise using a ratchet wrench with a 2 or 3 foot bar attached to it for leverage to get the belt off. Then install the new belt according to the diagram sticker at the front of the engine compartment.

Change alternator belt on 1996 buick riviera

The 96 Riviera has a motor mount that interferes with the removal and replacement of the serpentine belt. The motor mount must be loosened and the engine need to be lifted slightly to accomplish the replacement. Not good engineering on this model year.
