After 2 belts you should know about how to set the timing marks. With a 17 year old car, the water pump bearing and the belt tensioner are probably worn. They are the cheaper of the items on the belt. If you have A/C remember if it was on the last 3 times the belt failed. I would not suspect the alternator unless you replaced each one shortly after the belt broke.
If you have A/C, the compressor could have momentarily frozen if too much moisture is in the system.
A backfire can cause the timing to jump and will bust the belt. There have been several people on Fixya with similar cars driving along just fine and for no reason the belt pops. Get a good brand of belt and if somehow possible you see a date on it- go for a newer one that is not dry rotted hanging on a shelf somewhere.
Finally, check the alignment of the pulleys which would be the A/C and Alternator. One misplaced washer can change the track of the belt.

How to replace timing belt on a 1992 pontiac sunbird


1989–92 VEHICLES
  1. Disconnect the negative battery cable.
  2. Remove the serpentine belt and timing belt cover.
  3. Loosen the water pump bolts and release tension with tool J–33039 or equivalent.
  4. Raise and support the vehicle safely.
  5. Remove the crankshaft pulley.
  6. Carefully lower the vehicle, then remove the timing belt. Fig. 11: Exploded view of the timing belt assembly — 1989–92 OHC engines 87953118.gif
    To install:
  7. Turn the crankshaft and the camshaft gears clockwise to align the timing marks on the gears with the timing marks on the rear cover.
  8. Install the timing belt, making sure the portion between the camshaft gear and crankcase gear is in tension.
  9. Using tool J–33039 or equivalent, turn the water pump eccentric clockwise until the tensioner contacts the high torque stop. Tighten the water pump screws slightly.
  10. Turn the engine by the crankshaft gear bolt 720°to fully seat the belt into the gear teeth.
  11. Turn the water pump eccentric counterclockwise until the hole in the tensioner arm is aligned with the hole in the base.
  12. Tighten the water pump screws to 18 ft. lbs. (24 Nm), while checking that the tensioner holes remain as adjusted in the prior step.
  13. Install the crankshaft pulley, timing belt cover and the serpentine drive belt.
1993–94 VEHICLES
  1. Disconnect the negative battery cable, then partially drain and recover the cooling system.
  2. Remove the coolant recovery reservoir.
  3. If equipped, remove the A/C belt.
  4. Remove the serpentine belt.
  5. Disconnect the evaporative emission pipe assembly.
  6. Remove the crankshaft pulley assembly.
  7. As outlined earlier, remove the timing belt front cover.
  8. Align the marks on the crankshaft sprocket with the marks on the rear timing belt cover by rotating the crankshaft.
  9. Loosen the water pump retaining bolts, and release the tension with tool J 33039-A or equivalent.
  10. Carefully lower the vehicle, then remove the timing belt. Fig. 12: Timing belt installation and tightening specifications — 1993–94 2.0L OHC engines 87953119.gif
    To install:
  11. Turn the crankshaft and camshaft gears clockwise to align the timing marks on the gears with the timing marks on the rear cover.
  12. Install the timing belt, making sure that the portion between the camshaft gear and crankshaft gear is in tension.
  13. Using tool J 33039-A, or equivalent adjustment tool, turn the coolant pump eccentric clockwise until the tensioner arm contacts the high torque stop. Tighten the water pump screws slightly.
  14. Turn the engine by the crankshaft gear bolt 720°clockwise to fully seat the belt into the gear teeth.
  15. Turn the coolant pump eccentric counter clockwise until the hole in the tensioner arm is aligned with the hole in the base. This must be done with the engine at room temperature, approximately 68°F (20°C).
  16. Tighten the water pump screws while checking that the tensioner holes remain as adjusted as in step 15.
  17. As outlined earlier, install the timing belt cover.
  18. Install the crankshaft pulley.
  19. Connect the evaporative emission pipe assembly.
  20. Install the serpentine drive belt and the A/C belt (if equipped).
  21. Install the coolant recovery reservoir.
  22. Properly fill the cooling system, then connect the negative battery cable.

Timing belt instalation 92 sunbird


Click on the following free direct LinkS. These are for your 1992 Pontiac Sunbird. They have both: the 2.0L 4-Cylinder and 3.1L V6 Engine Diagrams with the various engine options (AC/No AC etc.)
This First Link has the Belt Diagram/Front Engine Diagrams you will need to remove in order to gain access to the Timing Belt Cover, which also has to be removed so you can remove the Timing Belt.
http://www.2carpros.com/car_repair_information/year/1992/make/pontiac/model/sunbird/1992_pontiac_sunbird_drive_belt_routing_diagram.htm
This Second Link are the Timing Belt Diagrams, complete with Instructional Diagrams.
http://www.2carpros.com/car_repair_information/year/1992/make/pontiac/model/sunbird/1992_pontiac_sunbird_timing_belt_diagram_marks.htm

As far as a Step-by-Step procedure: It would literally take dozens of Pages using this type of forum. I strongly suggest for your sake: to purchase a Haynes or Chilton Manual, available at most auto parts stores for around $20-$25. These have every step-by-step procedure you will need; including the Torques Specifications for each and every Bolt and/or Nut you are removing or loosening.

Let me know if this helped, or if you have additional information or questions. Feel Free to contact me at FixYa.com!

My 92 pontiac sunbird engine sound like it is missing. I changed the spark plugs and wires. It sounds better but still misses. What should I do.


I had the same problem with my 92 sunbird. after a long time of fooling around, we finally figured out it was the ignition module, it the part that is responsible for firing the spark plugs, mine was only running 2 of the four cylinders.

How easy is it to change water pump gasket on 91


There are two pulleys running in this engine, and the waterpump runs on the second pully behind a case. so you have to take almost everything off to get at it. Then, the waterpump is actually the belt tensioner for that pulley system. it is excentric (sp?) so when you turn it in place, it tightens the belt. then you secure it back with three bolts. The belt system in question connects the drive shaft with the cam shaft, So you do have to be Very Careful with the belt/ pulley alignment. i marked the pulleys very very carefully so i could get everything lined up again.

Water/coolent leaking from behind the timing cover


Water pump is on the left side of the timing belt in the cover and spins on an O-ring to adjust the belt. Their is a coolant pipe to the the thermostat housing behind the timing covers backing plate also. Be sure to replace the timing belt with the tensioner/ oil seals along with the water pump. Remove the timing covers back plate and you will find two bolt to the pipe as mentioned. It has a large o-ring behind it. Have fun with this one. From: Ronnie Wrench
