Yes a harmanic balancer from tha corolla is the same thing. I had to do the same thing with my 95 geo. It works out to be a lot cheaper buying for a toyota than a geo.

I have a '94 Tempo, it had a "ticking" sound. It was the "harmonic balancer" (crankshaft pulley) a local mechanic changed it for $60, the part cost me $120 (I work for a Ford dealership) $180 without employee discount. you can get one for much less at a junkyard if you can find one. Good luck, Sean

SOURCE: Mitsubishi Eclipse Harmonic Balancer 3.0L Removal

There is a panel inside the wheel well that you can take off that gives you perfect access to the harmonic balancer. A special tool is required. i had my dad make one because he has access to whatever he needs at the factory. but you can get them at the dealer. i have no clue how much they cost. I can't see any way of doing it without the special tool. after you get the tool its pretty simple to get off. it takes alot of force to break the bolt loose though. i used the handle off my jack as a cheater bar. hope this helps...

How do I replace mycrank sensor on a 1991 Buick Centry 3.3

Crankshaft Sensor REMOVAL & INSTALLATION 3.8L Engine On vehicles with a manual transaxles, the crankshaft position sensor is easily accessed from beneath the engine. On vehicles with automatic transaxles, the rack and pinion heat shield and the converter intermediate exhaust assembly must be removed first.
  1. Disconnect the negative battery cable.
  2. Disconnect the electrical connector at the sensor.
  3. Using a 28mm socket and pull handle, rotate the harmonic balancer until any window in the interrupter is aligned with the crank sensor.
  4. Loosen the pinch bolt on the sensor pedestal until the sensor is free to slide.
  5. Remove the pedestal to the engine mounting bolts.
  6. While manipulating the sensor within the pedestal, carefully remove the sensor and pedestal as a unit. To install:
  7. Loosen the pinch bolt on the new sensor pedestal until the sensor is free to slide.
  8. Verify that the window in the interrupter is still in the correct place.
  9. Install the sensor and pedestal as a unit while making sure that the interrupter ring is aligned within the proper slot.
  10. Install the pedestal and tighten the engine mounting bolts to 22 ft. lbs. (30 Nm).
3X Sensor
  1. Disconnect the negative battery cable.
  2. Remove the sensor harness connection to the sensor. Fig. 1: Unsecure the harness, then unfasten the bolt to remove the CKP sensor 86815102.gif

  3. Unsecure the sensor block bolt.
  4. Remove the Crankshaft Position (CKP) sensor from the vehicle. Inspect the O-ring for cracks and replace if needed. To install:
  5. Install the new O-ring if needed and lubricate with engine oil.
  6. Install the sensor into the hole in the block.
  7. Install the mounting screw and tighten to 71-88 inch lbs. (8-10 Nm).
  8. Attach the sensor harness connector, then connect the negative battery cable.
Dual Crank Sensor Sections 3 and 4 of this manual also cover testing, removal and installation, and adjustment of many computer controlled components.
  1. Disconnect the negative battery cable.
  2. Remove the belt(s) from the crankshaft pulley.
  3. Raise and support the vehicle safely.
  4. Remove the right front wheel and inner fender access cover.

How do you replace the harmonic balancer pulley on the 2000 oldsmobile intrigue

The short answer to your question is:

1. Raise the car on the passenger side and remove the front wheel.
2. Remove the belts on the harmonic balancer.
3. Remove the retaining bolt.
4. With a puller, jack the harmonic balancer off of the crank shaft. You can rent a puller at your local auto parts store. It is easiest to access the harmonic balancer through the fender, hence the need to remove the wheel.
5. You should also consider replacing the seal around the harmonic balancer to minimize the possibility of a leak later.
6. Install the new harmonic balancer and tighten the retaining bolt to the specified torque (I don't know this off the top of my head).
7. Replace the belts and wheel, and voila...mission accomplished.

This was a short answer to your question. You may wish to consult a repair manual for illustrations, torque specifications, additional instructions, etc. This job is not for the faint of heart. Good luck!

Where is the crank sensor located on a 1999 oldsmobile intrigue 3.5 engine???? easy to replace or not...

usually all crankshaft sensors are located right next to the main drive pulley (Harmonic balancer). As far as being easy is concerned some are not so easy as some require the removal of the harmonic balancer to get to it.. but you might be lucky Gm is pretty good at making the Crankshaft sensor accessible without removing the harmonic balancer.
