SOURCE: Harmonic Balancer

I have had the balancers come off just by unbolting it, and popping it off with a pry bar. Other times, I have used 2 pry bars, each behind the pulley, and popped it off. A few times, I have had to get out the puller. Just depends how long the balancer was on, and how rusty it is. But, they are not so tight that a puller will not do the job. Try the 2 pry bars, that usually works. Hope this helps, and thanks for choosing FixYa. The graciousness of a FixYa rating would be greatly appreciated. Thanks.

usually all crankshaft sensors are located right next to the main drive pulley (Harmonic balancer). As far as being easy is concerned some are not so easy as some require the removal of the harmonic balancer to get to it.. but you might be lucky Gm is pretty good at making the Crankshaft sensor accessible without removing the harmonic balancer.
