How can i keep the crankshaft from turning when removing the bolt?

Remove old crankshaft pulley ( Harmonic Balancer), by putting sturdy socket,think its 19mm, or 3/4 " on the center crankshaft bolt, with a good size breaker bar, wedge the breaker bar in between the suspension, and drive axle, to keep the breaker bar from spinning, while, you now turn the key inside the car, to engage starter, to spin the crankshaft,which may take several attempts, of turning the key, and putting socket back on, they are very stubborn,to break the center bolt loose,
Then remove harmonic balancer, with a PULLER, which requires 2 bolts, in the threaded holes, one on each side of the now empty center bolt hole, autozone , advance, has these to loan out, only requires deposit, which they give back to you, when you return it.
Put square key in slot on bare crankshaft, slide harmonic balancer,(crankshaft pulley,while lining up the square key,and tighten crankshaft bolt.

Place the drain pan under the radiator drain plug, open the plug and allow it to drain. Close the plug. Loosen the four nuts on the water pump pulley but do not remove them yet. Loosen the adjusting bolts in the alternator and the power steering pump with a wrench, push them away from the belts and remove the belts.

2Remove the bolts securing the fan shroud to the radiator support using a 10 mm socket. Remove the four nuts on the water pump pulley, then remove the fan and shroud as an assembly. Remove the bolts in the crankshaft pulley using a socket. Loosen and remove the crankshaft bolt using a socket.

Remove the top radiator hose. Extract all the 10 mm bolts securing the top and bottom timing covers and remove the covers.

4Install the crankshaft bolt temporarily. Use a socket on the bolt and turn the crankshaft clockwise until the mark on the crankshaft sprocket aligns with the timing mark on the block at the 12 o'clock position. Look at the camshaft sprockets and make sure the left sprocket has the "I" facing straight up and the right sprocket has the "E" facing up. At the same time, notice that there is a line on each sprocket adjacent to each mark--make sure they line up with the notch on the cylinder head at 12 o'clock. This allows for perfect alignment. If they do not come close to aligning, rotate the crankshaft one more time and they will align.

5Loosen the tensioner bolt and push the tensioner away from the belt. Loosely tighten the bolt to maintain position. Remove the belt.

6Install the new belt starting on the right side away from the tensioner. Keep all the tension on the right side. Loosen the tensioner bolt and allow it to apply tension on the belt. Do not tighten the bolt yet. Rotate the engine two turns clockwise and re-align the timing marks. Tighten the tensioner bolt to 35 foot-pounds.

7Install the timing belt covers. Remove the crankshaft bolt and install the crankshaft pulley. Reinstall the bolt and tighten. Install the radiator shroud and fan as an assembly. Place the fan on the water pump pulley, install the four nuts loosely, install the bolts in the fan shroud and tighten.

8Install the belts around the crank pulley, water pump pulley and alternator and pull the alternator up to tension the belt and tighten the bolts using a socket. Tighten the water pump pulley nuts using a wrench.

9Install the belt on the power steering pump, pull the pump out to tension the belt and tighten the bolts. Install the upper radiator hose. Fill the radiator with antifreeze

Hi,
The sensor is located to the right of the crankshaft behind the vibration dampner (harmonic balancer). You will need a balancer puller and a special tool to space the new sensor correctly.
(can be done also with eye spacing, but the tool is recommended to ensure proper spacing as to prevent damage to new sensor and / or harmonic balancer.) You will also need a strap wrench to hold balancer pulley in place while removing and re-installing balancer to crankshaft bolt. (helper required)

Procedure for replacement:
Remove negative battery cable.
Set parking (emergency) brake.
Release tension on serpentine drive belt and remove belt from harmonic balancer pulley. ( large pulley at bottom of engine)
Break loose lug nuts on passenger side front tire, do not remove bolts yet.
Raise and support vehicle on passenger side, remove wheel.
Remove plastic splash guard (cover) from passenger side wheel well.
Remove dampner / balancer center retaining bolt (counterclockwise, it is torqued very tight.) Use a strap wrench around pulley and have a helper hold that in place while using a 1/2" breaker bar and socket to turn pulley bolt out of crankshaft. Be careful not to rotate engine in a counterclockwise direction while breaking the bolt loose.
Using balancer puller, remove dampner / balancer pulley from engine.
You will now see the crank sensor to the right of the crankshaft bolted to the timing cover.
Disconnect sensor wiring and remove retaining bolts, remove sensor.
Put new sensor in place and screw in bolts, do not tighten them yet.
Reconnect wiring to sensor.
Now use special tool to properly space sensor. If you cannot find one at the parts store, you can space the sensor with the balancer pully held in place (not installed yet) and space the sensor evenly with the veins on the hub of the balancer pulley. Take your time and be sure it is as evenly spaced as possible.
Tighten sensor bolts.
Clean balancer hub free of any oil and dirt deposits using brake or carbeurator cleaner.
Reinstall balancer to crankshaft by tapping around the inner surface of pulley with a rubber hammer.
It is a press fit, so be sure you have it started evenly and progress slowly in a circular motion to ensure you are keeping it aligned straight with the crankshaft.
Reinstall balancer bolt using the same method as removal, torque bolt to 110 foot pounds, then tap around balancer again twice with rubber hammer, turn the engine 2 full revolutions clockwise using the balancer to crankshaft bolt, then tighten bolt an additional 1/4 turn.
Replace splash guard, put wheel on tightening lugs to finger tight and then wrench tight in a star pattern.
Lower vehicle until wheel makes contact with floor, tighten lug nuts to 115 foot pounds in a star pattern using a torque wrench.
Fully lower vehicle, remove jack.
Re-install serpentine drive belt
Re-connect negative battery cable.

End of procedure....Hope that helps!.....Mike

Good question, however you need to be able to keep the rest of the engine from turning while removing the bolt. While you are sitting front of the crankshaft you will turn it counter-clockwise. I hope this assisted you.

Instructions Difficulty: Moderate Things You’ll Need:

• Set of ¼-inch drive sockets ¼-inch drive ratchet Set of ½-inch drive sockets ½-inch drive ratchet Set of 3/8-inch drive sockets 3/8-inch drive ratchet Set of metric wrenches Floor jack Jack stands

Step1 Raise and support the vehicle on jack stands. Remove the intake air temperature wiring, the breather hose and intake air hose. Take off the air cleaner assembly. Step2 Remove the right wheel. Remove the accessory belts. Remove the crankshaft bolt and the crankshaft pulley. Remove the power steering bolts and the timing belt covers. Temporarily install the crankshaft bolt and turn the engine clockwise until the mark on the crankshaft pulley, which is a triangle stamped into the crank sprocket, is aligned with the corresponding triangular mark on the block. Step3 Make sure that the timing marks are aligned on the camshaft sprockets. These are a line on each sprocket that runs through a tooth on each sprocket. These lines should line up in the middle between each sprocket and point toward each other. If they do not line up, turn the crankshaft one more time and they will line up. It takes two turns of the crank to one complete revolution of the cam. Step4 Loosen the water pump bolts; using the 3/8-inch ratchet, turn the water pump clockwise away from the belt and loosely tighten the bolts to keep it there. Remove the timing belt. Make sure the timing marks are aligned and install the new belt starting on the right side from the crank sprocket and working counterclockwise. Keep all the belt tension on the right side away from the tensioner. Step5 Loosen the bolts in the water pump and rotate the water pump counterclockwise to apply tension to the belt. Watch the tensioner, which is above the water pump, and apply tension with the water pump until the pointer on the tensioner lines up with the notch above it. Lightly tighten the water-pump bolts. Step6 Turn the engine two more times and align the timing marks perfectly. Loosen the water-pump bolts and, using the ratchet, apply tension to the belt until the tensioner pointers are aligned. Tighten the water-pump bolts. Step7 Install the timing-belt covers and the bolts in the power-steering pump and tighten. Remove the crankshaft bolt and install the crank pulley and the bolt, then torque the crankshaft pulley bolt to 70 foot pounds of torque. Install all components in reverse order of removal.
