Location of Crank Position Sensor
I want to replace the crank position sensor on my 88 bonneville, but I can't find it. I have the front driver'* side wheel removed, but don't see it anywhere. Is it behind a cover? Anyone have any pictures they can post?
Thanks
Thanks

It'* behind the Harmonic Balancer on the passenger side. Not sure about Series 1 engines, but normally you must pull the balancer to change the semsor.

So now I've got a pull tool for the harmonic balancer, and a 28mm socket for the bolt on the harmonic balancer. How do I keep the crank from spinning when I am trying to unbolt it? I'm so close to having this done, but my chilton'* manual is entirely useless.

Remove the cover under the torque converter/flexplate and clamp a vise-grip on the flex plate to stop the engine from turning. I have also heard of people threading a bunch of small rope in through the spark plug hole on a cylinder to stop the piston but I have never tried this. The damper should not require a puller, it is a slip fit on the crank, although it may require a good tug.

You'll definantly want a puller for the balancer.....They don't just fall off with a tap of the wrist.
Also, the rope trick works...Just make sure you use twine, or rope that isn't freying or cheap and ratty that could leave a bunch of dust in the cylinder.

I don't know if I like the idea of the rope trick. It would create uneven pressure on the head, valves or piston. And if you do it on a stroke with an open valve, however slightly, light bend a valve.

I personally don't like the vice grips on the flexplate idea....they're pretty flimsy, and if you f it up....you have to pull the motor to replace it.

no no no, you guys are doing it all wrong! you gotta get one guy under the car, in the flywheel with a tire iron <has to be a strong guy too> and another one up top with a 24 inch breaker bar. that is the way to go, for both times we did it
