More than likely this stud you removed was one of the front cover blots, that actually works to seal the front cover up also.Remove that same stud again, and install some thread lock onto the bolt, then re=install it.This should correct your problem, Hope I could help...Rate me accordingly! thanks..

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.

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.

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.

Water pump replacement


Disconnect the negative battery cable, then drain the engine cooling system. 2. Relieve the belt tension, then remove the drive belt. 3. Remove the upper fan shroud, then remove the fan or fan and clutch assembly, as applicable. 4. Remove the water pump pulley. 5. If applicable, loosen the clamp(s) and disconnect the coolant hose(s) from the water pump. 6. Unfasten the retainers, then remove the water pump from the engine. Note the positions of all retainers as some engines will utilize different length fasteners in different locations and/or bolts and studs in different locations. To install: 7. Using a putty knife, carefully clean the gasket mounting surfaces. 8. Apply 1052080 or an equivalent sealant to the threads of the water pump retainers. Install the water pump to the engine using a new gasket, then thread the retainers in order to hold it in position. 9. Tighten the water pump retainers to specification: For the 4.3L engine, tighten the bolts and studs to 30 ft. lbs. (41 Nm). 10. If removed, connect the coolant hose(s) and secure using the retaining clamp(s). 11. Install the water pump pulley, then install the fan or fan and clutch assembly. 12. Position the serpentine belt over the pulleys, then carefully allow the tensioner back into contact with the belt. 13. Install the upper fan shroud, then connect the negative battery cable. 14. Properly refill the engine cooling system, then run the engine and check for leaks.

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.

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.
