It is a pain... I have heard that there was a "puller" that would have mad it a lot easier... I did not use one. I had to find a "chain wrench" (basically a long chain attached to a breaker bar that can be used to grip and turn large things... can often be found in Plumbing sections at home imporvement stores or hardware stores) to hold the crank pulley while a friend used a socket, two fairly long extensions to go through the access point in the passenger side front wheel well (tire must be off with car on jack stand) to break the nut holding the crank pulley in place. once that nut is off you either need to use a puller (recommended, but not used) or find a combination of crowbars, etc. that will give you enough leverage to pry the pulley wheel off. In my experience it was a real pain and there were several times that I thought I was making no progress at all... just keep going. :-)
Removing the crank pulley requires an impact wrench
Im not sure which direction the bolt turns to remove the pulley...the crank shaft turns in clock wise direction when engine is running.
could be the crank sensor, the go out. the have a reputation for that.
No it is not.
take off the belt, use a pulley puller to pull it then reinstall.
There is a large metric bolt right (17 or 18mm) in the center of the main crank pulley. Immobilize the crank using a vise-grip equiped with a locking chain. Wrap an old fan belt (cut-to-size) around the crank and protect the serpentine gooves of the crank pulley, then wrap the vise chain and clamp onto the crank. Use a good breaker bar, or impact hammer to break the bolt torque free counter-clockwise. Note: Don't remove the four 10mm bolts on the crank pulley. The whole thing comes off as one assemble piece.
Next to the crank pulley. Held on with 2 10mm bolts.
The crank shaft sensor is located on the bottom portion of the timing cover to the left of the crank pulley. Look for two wire harnesses and remove them along with the bolt.
the belt only goes around the crank pulley and alternator pulley
You can bypass the power steering pump pulley in your 1993 Buick regal 3.8 liter engine. Measure the distance around the other pulleys, without the power steering pump pulley. Take the measurement to your local auto-parts stores and ask for a belt of that measurement.
you have to remove the radiator and fans the main crank pulley and that should get you to the plastic cover take that off and then loosen the tension pulley and i would recommend changing the water pump and gasket at the same time
I am not sure if it has any but if there is they will be down on the crank shaft pulley
