Question about Buick Riviera

How do I change the serpentine belt on a 1996 Buick Riviera? I have removed the nut off the stud on the bottom leg of the cast bracket. I can't get to the stud and how do you get it out without damaging the threads on it?

As an ex dealer tech we use to hate that design. All of us ended up purchasing a stud removal tool that would take it out without any thread damage and it made into a fairly easy job.In your case after you have loosened up everything you can pull it out enough to get behind the bracket with some vice grips and get out that way,and where your gripping the stud it does not mater if you damage the threads some. I know this is not a lot of help I wish I could redesign it or loan you my stud extractor. Don't forget your floor jack and block under the oil pan to raise the engine to help get out the mount!!!

How to change serpintine belt for 97 buick le sabre


These were a real pain in the neck to change, you may want to take it to a shop if you don't have a lot of experience. The hassle of doing it yourself may outweigh the cost.
Here's the procedure, but it is easier said than done:

REMOVAL
  1. Remove the following components.
    1. The engine mounting bracket lower nut.
    2. The engine mounting bracket lower stud.
    3. The engine mounting bracket lower spacer.
  1. Remove the belt.
INSTALLATION

  1. Install the belt. Refer to Engine Mount in order to install the following components:
    • The engine mounting bracket lower nut.
    • The engine mounting bracket lower stud.
    • The engine mounting bracket lower spacer.daves944.gif

How to replace drive/serpentine belt for '97 buick le sabre 3.8? do u have to remove engine mount/bracket or just engine mount?


You don't have to remove the mount. Go thru the wheel well on the passenger side and remove the motor mount bolt just right of the crank pulley. Then remove the stud that the nut was on. Then remove the sleeve that the stud goes thru. Then you can change the belt.

There is no diagram for replacing my broken serpentine belt on my 1996 regal 3800


On the bracket that attaches the motor mount to engine, the lowest nut and stud must be removed (can reach by removing wheel and from bottom). Then remove spacer (that goes around stud), install belt then reinstall spacer, stud and nut.

97 Buick Lesabre-Am I crazy or do you have to unhook the engine mount to replace serpentine belt,I hope im just missing something. Thanks for any help. Don


Not the whole mount! Raise the car, remove passenger front wheel. Remove two clips that hold splash guard that is in front of the lower part of that engine mount. You'll then see the lower stud with a nut on it. Remove that nut, remove stud with a socket, then remove the spacer that was around stud between bracket and engine. That opens a gap to allow the belt to go on.

  1. Remove the belt guard or coolant recovery reservoir as required.
  2. For 1996-99 supercharged engines, perform the following:

    2. Remove the right-hand splash shield.
    3. Remove the connector from the crank sensor.
  3. For 1996-99 vehicles, remove the engine mounting bracket lower nut, stud and spacer. Carefully lower the vehicle.

CAUTION To avoid personal injury when rotating the serpentine belt tensioner, use a tight fitting wrench that is at least 24 in. (61cm) long.

  1. Take note of the belt's routing. Lift or rotate the tensioner using a suitable sized breaker bar in the square opening or box end wrench on the pulley nut. Remove the belt from the pulleys.

How to replace accessory serpentine belt on 1996 Riviera


The supercharged 3800 engine uses two accessory drive belts. The outer belt drives the supercharger. The inner belt drives the generator, power steering pump, coolant pump and air conditioning compressor. All driven accessories are rigidly mounted to the engine. Drive belt tension is maintained by the spring loaded belt tensioner. Each belt has its own tensioner.
Remove: Place a jack with a block of wood on it under oil pan to support engine. Caution : Be sure the wood block extends past the width of the oil pan to avoid damage. 
Torque axis engine mount bolt where it connects the mount to the engine mounting bracket. 
Electrical connector from crank sensor. 
Engine mounting bracket lower stud and lower engine to allow stud to clear frame rail. 
Raise engine and reinstall bolt into torque axis mount. Lower engine to allow spacer to be removed. 
Belt(s)

Istalling: Belt. 
Spacer. Remove bolt from torque axis bracket and lower engine. 
Electrical connector to crank sensor. 
Mounting bracket stud. 
Raise engine and install torque axis mount bolt. 
Tighten bolt to 87 Nm (52 lb. ft.) 

Good luck and hope this helps.
