Yes you can use crank bolt to set it to TDC or turn to adjust valve lash etc. This is how it is routinely done, just go in right direction only and it is easier to turn with plugs removed.

How do you remove a 1976 push rod for the fuel pump if it is stuck?
Try putting a large socket on harmonic balancer and try to rotate engine slowly -- make sure in neutral if std.
How do you rotate a Chevy 4.3 v6 motor by hand?
I use a socket with a short extension on a 1/2 drive ratchet on the harmonic balancer bolt.
How do you rotate the flywheel on a 1986 F-150 to get the starter to engage I want drive it to the repair shop.?
You Can Rotate The Engine By Turning The Harmonic Balancer, ( Crankshaft Pully Mounts On It ) By Using A Socket And Extension That Fits The Nut Holding The Balancer On It Will Be Rather Large Maybe 1 &1/2 Inch Or More. You Can (maybe hold the fan belt tight enough & turn the engine this way. Before I Did All This I Would Make Sure Its The Ring Gear & Not The Starter Drive. Good Luck
How do you rotate the engine in a 1991 3.1 V6 Cavalier?
Rotate? As in rotate the crank manually? Remove the Passenger side splash panel and turn it with an 18mm socket.
How do you rotate the flywheel on a 1989 Chevy Suburban?
There is a big bolt that is inside of the bottom pulley on the front of the engine, It is the bolt that holds the balancer on . Get a socket that fits that bolt and then turn the engine with that and that will rotate the fly-wheel.
How do you set the timing on a Buick 3.8 engine?
the timing is computer controlled when there is no dist.---which became standard in 1987---previous to that you rotate the dist. and set it to the number of degrees advance that the decal under the hood says---some where around 10---the timing marks are behind the harmonic balancer (which is on the end of the crankshaft)
How do you set the timing on a 91 Seville?
Warm your engine up before doing anything. Open the hood and remove the bolt from the distributor. Hook a timing light to the first cylinder and point it to the harmonic balancer. Rotate the distributor until it aligns with the 10 degree mark, then add the bolt back and tighten it.
Location of crankshaft sensor on 92 Pontiac Trans Sport?
On 1990 through 1995 General Motors 3.8 L engines, the crankshaft positioning sensor was located under the harmonic balancer on the left side of the engine. The harmonic balancer is attached to the main crankshaft and must be removed through an access hole located in the right passenger wheel well. Remove the right front passenger tire after jacking up in stabilizing the vehicle. Inside the wheel well is a small plastic panel that can be removed to access the harmonic balancer mounting bolt. Remove this bolt from harmonic balancer. Using a small wheel puller on the harmonic balancer, gently tap and tighten the wheel puller to remove the harmonic balancer itself. Caution -- be very careful while doing this! The harmonic balancer has a soft aluminum rings attached to it that can easily be bent during the removal process. If they are bent, they will not work properly and will damage the crankshaft positioning sensor! Once the harmonic balancer is removed the crankshaft positioning sensor and wiring is exposed for replacement. Follow the wires leading out of the crankshaft positioning sensor to the electrical wiring coupling. Uncouple this union to disconnect the electrical wires of the crankshaft positioning sensor. Carefully clean the area around the old sensor while still mounted on the vehicle. He is a permanent magic marker and carefully outline for Mark the position of the harmonic balancer before removal. This Is Very Important! If the new crankshaft positioning sensor is not in the precise position as the old one removed, it can cause a no pulse situation to the mission module, which produces the sparkplug timing and firing to the sparkplugs. Crankshaft positioning sensor is held on to the engine by two bolts. Carefully remove these two bolts and the old sensor. Clean the area behind the old sensor with steel wool to make a clean surface for the new sensor mounting. But the new crankshaft positioning sensor in place were the old sensor was removed, follow closely the marks made earlier to position the new sensor at the right location. Mount the new sensor with the two bolts that were removed. Attach the electrical wires from the new sensor following the same path as the old wires on the sensor removed and reattach the electrical coupling to the wiring harness. Carefully replace the harmonic balancer back in place on the crankshaft. Do Not Force the harmonic balancer if you feel any resistance! The circular aluminum fins attached to the harmonic balancer may be pressing against the crankshaft positioning sensor if the crankshaft positioning sensor is not aligned correctly. If you feel any resistance from the harmonic balancer you'll have to climb into the engine area and carefully check to see if the new crankshaft position sensor is in the right location to allow the aluminum fins on the harmonic balancer to fit between slots on the new crankshaft positioning sensor. If the slots do not accept the fins on the harmonic balancer, slightly loosen the two mounting bolts for the sensor and reposition it where you can clearly see that the slots will accept the aluminum fins on the harmonic balancer. Once you have done this, lightly slide the harmonic balancer back into place and check again at the aluminum fins fit cleanly into the slots of the new crankshaft positioning sensor. With the sparkplugs removed, it is possible to rotate the crankshaft and harmonic balancer clockwise to ensure the aluminum fins pass cleanly through the slots of the crankshaft positioning sensor. Once you have verified this, re-tighten but not over tighten, the mounting bolts on the crankshaft positioning sensor. Reinstall the harmonic balancer on the crankshaft and replaced the bolt that holds it to the crankshaft. Be sure to tighten this bolt securely. Again and rotate the crankshaft clockwise by hand very slowly. Listen and feel for any resistance at the harmonic balancer to this turning. If you hear any, remove the balancer and check the crankshaft positioning sensor alignment again. If no resistances felt, the job to be done. Using a cheap spark detection tool, available at most part stores, you can have someone cranked the engine and check for spark plugs. If you have installed the new crankshaft positioning sensor correctly, have it aligned correctly so that the aluminum fins on the harmonic balancer ride smoothly through the slots, you should see spark now at the plugs. This is assuming of course all of the components, the ignition module, the coil packs, and electoral connections are in good working order. When the engine is running and the harmonic balancer rotating on the crankshaft with the aluminum fins sliding through the crankshaft positioning sensor, this provides electrical control pulse to the ignition module, that tells it where the crankshaft position is and regulates when the spark to each plug is released. In this Distributorless design, the crankshaft positioning sensor is a simple Hall Effect switch. While not very complex, it is an integral part of the Distributorless SPARC system for the vehicle and often is suspect to failure. The failure of the crankshaft positioning sensor causes a no spark situation at the plug and the engine just stops running. This can happen at any time. Meaning, you can be driving along, the engine is running fine and then it just suddenly quits! After a short period of time, you can suddenly restart the engine and it runs fine again. This condition generally is caused by the crankshaft positioning sensor overheating and stops producing the needed control pulse to the ignition module which controls the spark at the plugs. Many mechanics misdiagnosis this problem when the vehicle is brought in. 1990 to 1993 onboard computers do not have a trouble code for a bad crankshaft positioning sensor. 1994 and up vehicles have a different onboard computer, called OBT2, and a trouble code for this condition. An intermittent crankshaft positioning sensor can also cause erratic engine operation, from rough idling and power loss, to poor gas mileage. As a general rule, if your vehicle as the 80,000 to 125,000 miles on it, it is a good preventative measure to replace the crankshaft positioning sensor, even if you are experiencing no problems with it. The crankshaft positioning sensor only costs about $35 at most part stores but because of its critical role, it is a part not be ignored in preventative maintenance. I hope this helps some people resolve a serious condition I call The Sudden Stop Syndrome. Otherwise, a 3.8 L V-6 engine has been a fairly reliable engine for General Motors. If you have any questions, be sure your vehicle is serviced by a competent mechanic. C.08 - DERICKUSA1
How do you adjust ignition timing on 1995 ford bronco 5.8?
If it has a distributor, there is a bolt near where the distributor shaft enters the engine. Loosen it. Use a timing light gun, it connects to the number 1 cylinder spark plug wire and shoots a light. Aim that light on the harmonic balancer while the engine runs. There should be a little metal/plastic tab with degree markings on it. When the light shines, you should see a mark (usually a groove) on the harmonic balancer right in the range of that metal/plastic tab. Rotate the distributor to make that mark/groove line up with the right timing degree. Dont have a timing light gun and dont want to buy one, do it by ear...with just slight movements of the distributor, you can hear when the engine is running its best. Won't be perfect, but will be close enough. If it has coil packs and is electronically controlled, you can probably just reset the computer (disconnect the battery and leave it till the next day).
How can i spin manually the flywheel on a 03 neon....i have tried to rotate it from the drive shaft and it wont spin...why...is there any other way to spin it?

What would make a loud clanking noise at the front of a 92 Buick Century engine when idling that goes away when revved up?
The fan blade may be loose. You can determine this when the engine is off by moving the fan blade by hand or by watching it rotate when the engine is running. if its a real loud then i would check out the harmonic balancer. to check this. with the engine OFF grab the belt and try and move it back and forth if it does and u hear a noise than its the balancer. i had the same problem i fixed it my self saving $$$$$$$, but it was a pain....u need atleast 2 people to fix this. good luck On my 94 Buick Century the water pumb made a loud clanking noise at idle, which would go away when revved up. A day later the water pump seized up and the belt smoked up a storm where it rubbed over the stuck pulley.
