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.

Timing chain 96 maxima broke


Check your owner's manual for the recommended mileage for replacing your timing chain. Replacement for a Nissan Maxima is 60,000 miles.2 Locate the timing chain. Replace it if the automatic chain adjuster (also known as the tensioner) is damaged or worn.3 Release the pressure in the fuel system, drain the cooling system and disengage the negative battery cable. 4 Undo the upper radiator hose, engine drive belts, power steering pulley and pump with bracket, air duct, passenger front wheel and engine side and undercovers, front exhaust pipe, cylinder head front mounting bracket and head cover, rocker cover, distributor and distributor cap and spark plugs.5 Take off the intake manifold support and move the No. 1 piston at "Top Dead Center" (TDC) of the compression stroke.6 Disconnect the cylinder head front cover, water pump pulley, thermostat housing, upper and lower tensioner and slack side timing chain guide, idler sprocket bolt, camshaft sprocket bolts, sprockets, mounting caps and camshafts. 7 Disengage the cylinder head with the manifolds, idler sprocket shaft, upper timing chain, center crossmember, oil pan and strainer assembly, crankshaft pulley, engine front mount and bracket and the front timing cover. Remove the oil seal and unfasten the timing chain cover, idler and crankshaft sprockets and the oil pump drive spacer. 8 Unfasten the timing chain guide. install Your Timing Chain 1 Grease the oil seal lip with engine oil and place it in the front cover. Verify that the No. 1 piston is at "Top Dead Center" (TDC) of the compression stroke. 2 Reconnect the crankshaft sprocket (marks should point toward the engine's front), oil pump drive spacer and timing chain guide and the lower timing chain. Line up all mating marks.3 Hook up the crankshaft sprocket and pulley, lower timing chain, front cover assembly, engine mount and front mounting bracket, oil strainer and pan assembly and center crossmember.4 Reattach the upper timing chain, idler sprocket (to the back side), cylinder head assembly, idler sprocket bolt and exhaust and intake camshafts. Place the intake camshaft knock pin at 9 o'clock and the exhaust pin at noon. Connect the camshaft bearing caps and distributor brackets and secure all mounting bolts.5 Eliminate any old material from the pan and cylinder block mounting surfaces. Rub on a 3.5 to 4.5mm bead of liquid gasket over the oil pan and cylinder block.6 Attach the upper timing chain to the idler sprockets and secure the cylinder head bolts.7 Refill the cooling system. Hook up the negative battery cable and any other disconnected items. Start the engine and look for leaks.

ALTERNATOR REPLACEMENT


Assuming this is a XG 350, the process is lengthly.
1. Remove the RH radiator cooling fan (two 10mm bolts at the top & wiring harness connector to it).
2. Lift vehicle to remove the Right Front wheel (then remove 4 10mm bolts securing the plastic splash shield & remove it)
3. Loosen the 14mm nut on the alternator belt tensioner pully
4. Loosen the tension on the belt by rotating (counter-clockwise) the 14mm bolt at the bottom of the idler pully and remove the belt.
5. remove the pully & the idler pully (three 12 mm bolts)
6. Loosen the 14mm nuts at the top and bottom mounting points of the alternator.
7. Using a floor jack (or vehicle lift), support the engine using a jack-stand & 2x4 piece of wood under the oil pan.
8. This is tricky - lift the engine 'SLIGHTLY' to take pressure off the front engine mount - loosen the 17 mm nut on top of the mount itself and observe engine movement. If the engine moves upward 'slightly' remove the 17mm nut - if not, raise the engine slight more until you see the mounting bracket rise off the mount.
9. Remove the remaining 17mm nut (deep well socket), and two 17mm bolts and remove the engine mount bracket.
10. Here's another tricky step. Some 350's bottom Alternator bolt bores are 'SLOTTED'... some are NOT. You'll need to determine wether you'll need to REMOVE the lower bolt, or just loosen the mounting sleeve at the bottom bolt. If it's 'sleeved', I use an air hammer to loosen the sleeve. If it's not slotted, I remove the lower bolt (it's the only way to remove the alternator and pry it off).
11. At the top is an "L" bracket which uses two 12mm bolts to attach it to the engine (head). One of the two 12mm bolts is difficult to get to -- do your best to remove it because the battery cable to the alternator is in the way.
12. Disconnect the alternator wiring (battery cable & regulator harness connector)
13. Lift the engine as high as it will go & pry the alternator off its lower mounting.
14. manuver the alternator upward taking care not to damage the radiator.
15. Installation is in reverse order.
NOTE: If your XG's lower mounting point was slotted, your task is easy. If it isn't, your task now becomes more difficult as you must align the new alternator to facillitate re-insertion of the lower bolt.
PS If not slotted, I use a telliscoping magnet to help re-insert the lower bolt.

Any other way to to replace the serpentine belt from a 1997 park avenue without having to raise the moter mount...there is a mount that blocks the belt from sliding off


Yes at the bottom by the air conditioning compressor is a spacer/bushing that runs through the mount and into the block.I think the nut is an 18mm it is on a stud that is an inverted torx towards the bottom.Many times removing the nut will also unthread this stud.If it does not you will need the inverted torx to remove it .After that is out wiggle that spacer around and it will dislodge and allow just enough room to get that belt off and back on.

How do replace the tensioner pulley on a 2.2 engine 4 cyl. 1998 chevy cavelier .


there are two bolts located behind the pully on the mounting bracket arm, (you have to use a 1/2 inch drive bar in the idler pully to move it so you can see the bolts) That will help you with locating the bolts, while you are moving the pully you might as well take the belt off to save time, After you remove the old idler pully install the new one, use your 1/2 drive bar on the pully to put your belt back on. Pretty simple job, good luck!

that is not an idler pully that is the power steering pully if you feel through the holes in the pully you will feel the 13 mm head bolts that hold the pump to the block remove those bolts the pump will drop down and you can then remove the water pump also you have to remove the studs using the inverted torx end on the stud to unscrew it then the mount will come out

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.
