it is behind the harmonic balancer.
I tried to change the harmonic balancer of my biuck lesabre 1994, but i can't remove the old one, the bold in the center is very , very tight and i don't know the type of screw, right or left turn.
The flywheel has to be held in place by a holding tool, Remove the mounting bolt, then use a balancer remover to pull the harmonic balancer.
its behind the harmonic balancer attached by two bolts but you must first take off the balancer to get to it
On my 1994 Lesabre it is under the dash about center at edge of carpeting
Remove belt, balancer bolt and get a balancer puller to remove the balancer. Unbolt and unplug sensor to replace it. An air impact wrench that is strong will get the bolt loose.
