What direction do you turn to remove the crankshaft pulley bolt for a 1996 oldsmobile 88

There are 4-8 mm bolts holding the pulley on. Usually, you can hold the pulley by hand while breaking them loose. If they are too tight or you can't hold it tight enough, leave the serpentine belt on to help hold the pulley while you begin to loosen the bolts.

1 Locate the crankshaft pulley on your vehicle. This is usually on the driver's side, but may be on the passenger's side if your timing belt is located on the passenger's side. Place the end of the tire wrench over the lug nuts of the appropriate wheel of your vehicle and turn the wrench about 45 degrees. 2 Put your emergency brake on. Then use the floor jack to jack up the vehicle's front jack point (an extension of the frame).3 Put the jack stands under the frame of the vehicle. Then, lower the vehicle onto the jack stands. 4 Continue to loosen and remove the lug nuts, and pull the wheel off.5 Remove the plastic rivets that hold the splash guard in place in the wheel well. To do this, you need to wedge the screwdriver in between the rivets and the splash guard and pry them out.6 Locate the crankshaft pulley. It will be right behind the splash guard you just removed.7 Remove the crankshaft bolt using the crankshaft bolt remover tool. Place the tool over the crank pulley bolt in the center of the pulley. This device prevents the pulley from rotating while you loosen the bolt.8 Place the socket end of the impact wrench over the crankshaft bolt remover tool. Set the impact rench to turn counterclockwise and turn on your air compressor. Wait until the compressor is fully charged. Then, work the bolt loose. It may take a while as this bolt normally requires in excess of 800 ft lbs of torque to remove.9 Attach the arms of the crankshaft pulley removal tool over the pulley and tighten the tool to the pulley using the tool's supplied bolts. Continue to tighten the tool using the bolts until the crankshaft pulley is pulled off the crankshaft.

Timing belt installation

Timing Belt and Sprockets REMOVAL & INSTALLATION 2S-ELC, 3S-FE and 5S-FE Engines

1. Remove the timing belt covers as previously detailed.
2. Raise the engine just enough to remove the weight from the engine mount on the right side.
3. Remove the thru-bolt, two nuts, and right hand mounting insulator.
4. Remove the retaining bolts and remove the right hand mounting bracket (from the side the alternator was removed from).
5. Remove the timing belt and timing belt guide. If the timing belt is to be reused, draw a directional arrow on the timing belt in the direction of engine rotation (clockwise) and place matchmarks on the timing belt and crankshaft gear.
6. Remove the bolt retaining the No. 1 idler pulley and tension spring.
7. Remove the No. 2 idler pulley.
8. Remove the crankshaft timing gear , if it can not be removed by hand, use two flat bladed tools to pry it off. Make sure to position shop rags to prevent damages to the components.
9. Remove the nut retaining the oil pump pulley. To install:
   
10. Align the cutouts of the oil pump pulley and shaft, and slide the pulley on. Retain the pulley while tightening the nut to 21 ft. lbs. (28 Nm).
11. Align the crankshaft timing pulley set key with the key groove of the crankshaft pulley, then slide the pulley on.
12. Install the No. 2 idler pulley with the bolt and tighten to 31 ft. lbs. (42 Nm). Be sure the pulley moves smoothly. NOTE: Remove any oil or water on the idler pulley and keep it clean.
    
13. Temporarily install the No. 1 idler pulley with the retaining bolt. Hint: use a 1.65 inch (42mm) bolt in length. Do not tighten the bolt yet. Install the tension spring. Pry the pulley toward the left as far as it will go, then tighten the bolt.
14. Turn the crankshaft until the key groove in the crankshaft timing pulley is facing upward. Install the timing belt on the crankshaft timing, oil pump, No. 2 idler and water pump pulleys. NOTE: If the old timing belt is being reinstalled, make sure the directional arrow is facing in the original direction and that the belt and crankshaft gear matchmarks are properly aligned.
    
15. Install the lower (No. 1) timing belt cover and new gasket with the four bolts.
16. Align the crankshaft pulley set key with the pulley key groove. Install the pulley. Tighten the pulley bolt to 80 ft. lbs. (108 Nm).
17. On 2S-ELC engines, turn the crankshaft pulley and align the 0 mark on the lower (No. 1) timing belt cover.
18. Align the camshaft knock pin with the matchmarks on the oil seal retainer.
19. On 2S-ELC/USA engines, align the knock pin with the pin hole on the timing pulley E mark side. On 2S-ELC/Canadian engines, align the knock pin with the pin hole on the timing pulley. On 3S-FE and 5S-FE engines, align the knock pin with the groove of the pulley, and slide the pulley onto the camshaft with the plate washer and set bolt. NOTE: On 2S-ELC engines, make sure that the Matchmark on the oil seal retainer and center hole of the small hole on the camshaft timing pulley are aligned.
    
20. Using the removal tool to hold the pulley stationary, install and tighten the pulley set bolt to 40 ft. lbs. (54 Nm) on the 2S-ELC and the 3S-FE. On the 5S-FE, tighten the set bolt to 27 ft. lbs. (37 Nm).
21. On 3S-FE and 5S-FE engines, turn the crankshaft pulley and align the 0 mark on the lower (No. 1) timing belt cover.
22. Install the timing belt and check the valve timing as follows:
    1. Align the matchmarks that you made previously, and install the timing belt onto the camshaft pulley.
    2. Loosen the No. 1 idler pulley set bolt 1⁄2 turn.
    3. Turn the crankshaft pulley two complete revolutions TDC to TDC. ALWAYS turn the crankshaft CLOCKWISE. Check that the pulleys are still in alignment with the timing marks.
    4. Tighten the No. 1 idler pulley set bolt to 31 ft. lbs. (42 Nm).
    5. Make sure there is belt tension between the crankshaft and camshaft timing pulleys.
23. Install the upper (No. 2) timing cover with a new gasket(s). On the 5S-FE, align the two clamps for the engine wiring harness with the cover mounting bolts.
24. Install the spark plugs.
25. The remainder of installation is the reverse of removal. Tighten each component to specifications.

camshaft pulley no pulley on the camshaft? Crankshaft pulley is taken off with 3 small bolts theres a kit at your local parts shop to take the pulley off a 3.8l with special bolts to go in it to pull it off.

remove the pressure and return line, the belt, remove the mounting bolts. Use a "power steering pulley puller" to remove the puller. This tool also works as an installer.

On the passenger side behind the crankshaft pulley. You have to remove the serpentine belt and crankshaft pulley, which is best done through the wheel well. Removing the pulley can be quite difficult as some of these require a special puller. It may be worth the 1 hour of labor to just have a shop do it as this could consume a whole day if you don't have the tools for the job. With the crankshaft pulley off it would be wise to inspect/replace the crankshaft seal. There is also a bit of a trick installing the new sensor, it has to be aligned carefully so that the crankshaft pulley vanes hit it.

There are two crankshaft sensors located at the edge of the harmonic balancer. That's the large wheel coming out of the engine, passenger side, the wheel that powers the serpentine belt. One sensor is the crankshaft position sensor and the other is... I forget... crankshaft angle sensor or something. I replaced both on my car. I don't know wich one is your problem. When you buy a sensor, get the one with the mounting bracket already attached. They had problems with the sensor getting damaged from being adjusted wrong. Having the bracket already attached gives you the right adjustment.

Remove the serpentine belt. (It has a tensioner wheel. When that is moved, the belt becomes loose and can be removed.) With an 18 mm wrench, turn the crankshaft until one of the openings in the metal fin is at the sensor, giving a space where the sensor can be removed. One sensor is reachable from the top, but it is real hard to see. The other is reachable from underneath. My guess is, the lower one is you problem only because my lower one failed twice and the upper one only once. Your son has to crawl underneath, unhook the wire from the sensor, and unbolt the sensor mounting bracket. Put the new one in. Keep your fingers crossed.

i use a 1/4" drive 10mm long socket and insert it through the openings on the pulley and turn the pulley to acess all the three or four bolts and the pump should be out but removal of the p/s belt will make it even easier!!
