Question about 1997 Pontiac Grand Prix

1 Answer

Serpentine belt Because of the supercharger, this car has two belts. The belt off the water pump was gone when I raised the hood, so I have to figure out the routing. Any suggestions? I thought there would be a routing schematic, but it's not under the hood.

    Same problem. Parts store had two different belts, 93" and 93.5". But incorrect routing diagram. What is worse is the original belt was still there, but seemed to have picked up about 8-19" of slack! Be aware of the tensioner pulley, upon popping the hood we found it frozen in place (won't rotate at all).

2006 Mustang GT 3v soch supercharged V8. Where can I get a diagram showing how to replace the serpentine belt?


Diagrams are available from Gates, Dayco, and Continental (Contitech) for most serpentine belts. Replacing the belts shouldn't be undertaken unless you have the proper fitment tools and are familiar with alignment procedures. Serpentine belts are typically replaced every 60K miles and Gates Racing Blue are the finest on today's market, lasting bit longer under demanding driving conditions. Replace any accessory belts, the crankshaft front oil seal and water pump at the same time... you will thank me later!

Maybe your serpentine belt is slipping or gone. Not sure if the water pump runs off the same belt as the alternator on this model.

Serpentine belt on a 3800 supercharger


there should be a decal under the hood somewhere that shows the belt routing. if its gone you can probably go to the library and find a book of your car that will show the routing and you can either draw a picture or take a photo of it.

Serpentine belt replacement


Originally the diagram was on a sticker somewhere in the engine compartment or on the underside of the hood, if that is gone, try the auto parts place where the belt was purchased, they may be able to help. A Ford dealership may be kind enough to provide a diagram also.

How do I remove the belt so I can remove the Water Pump?


If you are referring to serpentine belt, Thisis how to do it. Lift the hood and prop it open. Find thelock nut on the serpentine belt and use a wrench to loosen it. Turn the adjustment bolt counterclockwiseto remove the serpentine belt. This bolt is located under the water pump hose.Remember how you remove the belt so that you can reroute the new beltcorrectly. Install the new serpentine belt by securingit on the pulleys in the same route as the old belt. Check the belt routing onthe underside of the hood to make sure you get it right. Create tension in the back of the belt byturning the adjustment bolt clockwise. Check that the belt is on each pulleyproperly. The belt should be centered on each pulley, not on the edge.Tightenthe lock nut to secure the serpentine belt in place.

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.

Serpentine belt broke and i think the water pump is bad


The battery light and brake light are on because the belt isn't turning the alternator. The house with columns means it is low on antifreeze. You need to put the belt back on an check for antifreeze leaks. I would say you waterpump likely locked up and roasted the belt and that is where the antifreeze is leaking also.
