SOURCE: can not get the serpentine belt around the motor mount

on some of the 3.8 you do have to remove the motor mount,there is no way around it. It is not as bad as it sounds.

SOURCE: Serpentine belt

You do not need to remove the mount, but one of the bolts on the lower portion of it. You will need to remove the 15mm nut, then the stud comes out with a reverse torx bit. The collar in between the mount will come out with some work. Then you can remove the belt with the mount still in place.

You need to remove the mount, no other way to get the belt on, Labor time is over 1 hour for someone that has done them before.

My belt for the supercharge broke can I still drive the car?? 1997 riviera


Yes, you can still drive the car. No real damage will occur, but performance will be poor. It's not impossible to change the belts, just time consuming with the way the belt is run around the motor mount bracket.

Im going to have to change my serpentine belt on a 96 buick park avenue. 3800 non supercharged. Looked at it yesterday and it looks like I have to unbolt motor mount to get the belt off? Is there an easier...


yes.that is the only way.You have to unbolt the motor mount. To replace the serpentine belt on a V6 3800 series non-supercharged motor, you must jack up the motor and remove a motor mount. Before going any further make sure that the factory belt diagram sticker is still somewhere under the hood; if not, make a detailed diagram of the path of the belt. You must then use a breaker bar with a socket (I believe 13/64") and pull it toward the front of the car to release the belt tensioner. Put the new belt on, tighten it, put the mount back on, and lower the jack. Thanks. keep updated for any more query.you can rate this solution and show your appreciation.

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.

Need to replace the superchager belt, i know that it isn't easy, remove the lower moter mount spacer of the idler pully mounted inside the mount? '96 riviera


If memory is correct it should be driven by the serpentine belt, which runs through one of the engine mounts. 
To change the belt you'll need to support the engine (by something other than the oil pan) and pull the engine mount. 
== here is another opinion== First you have to remove the belt to the alternator then you can remove the belt to the supercharger. To do this you will need a 19/32" socket and breakerbar or long ratchet.  
Put ratchet on belt tensioner nut and pull toward front of car then pull belt off. There is a separate tensioner for each belt. 
I hope this helps and since your doing all that work might as well sevice the supercharger too which is always forgotten.
You can buy a superchaarger lubricant from the dealer or, according to the manual. You can use synthetic 10W30 weight oil, which is a much cheaper route. 
The filler is a small plug located at the bottom of the goose neck of the supercharger. You need an allen wrench to unscrew it. The oil should be up to the bottom of the threads for the screw plug.
Good luck and hope this helps. Dubble check though, i had a long day.
