I had used three bolts they have to be 6mm thik and like about 6 inches long then you install some flat washers by the head and use a regular crank pulley remover, you'll see three little holes inside the groevs at front side of pulley and there is where you install the bolts

I'm trying to remove a harmonic balancer. I've got to the point of taking it off. The pulley remover is placed. But the bolt when completely down only turns the balancer. How to fix please


Are you using a gear puller or an actual harmonic bal. puller? You can use air tools(carefully), or to hold the balancer/pulley still, use a chain wrench with an old belt wrapped around to prevent damage. I would not recommend a 2 or 3 jaw type gear puller.

How do i replace a crank shaft sensor on a 2001 buick lesabre


The crankshaft sensor is located behind the harmonic balancer. There is a special tool you can rent/loan from your local auto parts store in order to remove the harmonic balancer. Once it is off 2 bolt hold the crankshaft position sensor in place. Note there could be many other factors causing your engine to stall or not restart; but those crank sensors do tend to go out on those engines.

What makes the car die after running for so long


Loss of spark is the common reason on this year of buick, that means you either have a defective Crankshaft position sensor or a defective Ignition control module, either one can cause the symptom. Of the two parts the crankshaft position sensor is the most common failure point, to replace it you must remove the front crank pulley and the harmonic balancer behind that pulley, the crank sensor is behind that and is triggered off the harmonic balancer. You access the pulley through the passenger wheel well, you must remove the plastic or rubber splash guards to access it, you will need some special tools, a harminic balancer pulley puller of course will be required. There is also a special tool needed to set the air gap from the sensor to the pulley, so to get around that tool measure the old sensors air gap with a feeler gauge and set the new one the same.

Where is the crankshaft sensor on a 3.8L in a 97 buick lesaber


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

Find crank position sensor


The crankshaft position sensor should be located behind the vibration damper/harmonic balancer and it will have to be removed before the crankshaft position sensor can be replaced. (Let me know if you require assistance with the proceedure)

Also, it usually requires a special tool to align that sensor (available from most auto part stores) and if the sensor is not properly aligned then damage to the sensor or the tone ring can occur.

Here is an image of the crankshaft position sensor with the vibration damper/harmonic balancer removed.

Crankshaft pulley (harmonic balancer) removal- disconnect neg battery cable, remove belts, it would be a good idea to soak the bolt w/ penetrating oil overnight, there is a special 'crankshaft pulley holding tool' available to secure the pulley while removing and installing the bolt. Some parts stores loan tools for free if u purchase parts from them, I don't know if this is available, but it would be worth checking out. Attach holding tool and remove bolt securing pulley. Carefully remove pulley from crankshaft, Do NOT pry off. Remove key from crankshaft sprocket,
Install: install key on crankshaft sprocket, slide pulley on, apply clean oil to bolt threads but NOT to washer contact surfaces, secure crankshaft w/ holding tool, tighten to 159 ft lbs (91-93 Accord), install belts, re-attach neg cable.
