Crank Sensor with Engine out.

[A-Rok]

Hi, been a member here a while, but never actually posted.
It always got depressing because my SHO has been parked for a year.
Now I'm finally getting my new engine in, however, the previous owner had stripped the crank sensor off (it looks like he just yanked it out). Would the task of replacing it be much easier with the motor in the car, or out of it?

Also, any extra advice on replacing this would be greatly appreciated, thanks.

It depends on wether you have the crank bolt off or not. If the crank bolt is off, which i am assuming it is then the job will be much easier with the engine out of the car. Gap the CPS at .78mm or .03in. SHOtimes.com has a good how to on this job. Good luck.

Oh yeah, the crank bolt is still on both engines.
I need to take the old sensor off the old engine and install it in the new one.
So regardless, I need to get it off out of the car, but I think it would be easiest to replace it into the new one in the car.

Any suggestions or other ideas?

You may want to spend the money now and put a new sensor on... thumb

Get a new CPS sensor. Only $35 from Autozone down here. Not sure what it would cost you up there. It would be a lot easier to replace the CPS with the engine out. Try using a strap wrench on the crank pulley to immobilize the crank so you can loosen the crank bolt. If it were me what I would try would be an extension pipe on the strap wrench so that when you rotate the engine counterclockwise the extension pipe will catch the group. Then a four foot long cheater pipe on your breaker bar ought to do the trick on the crank bolt. Jump up and down on it if you have to.

I'm sure there are some other good (possibly better!) ideas out there for you. Probably a few people on here who have had to loosen a crank bolt with the engine out of the car. Hopefully they'll share what they did.

The CPS (Wells SU242, $34.99 AutoZone) is mounted with two stainless steel screws, probably M4, 10mm or 12mm long. Below are a couple of pictures showing its location and gapping. You will need to position the sensor vanes by turning the crankshaft to have a gap at the CPS so it can be installed. The magnet portion of the sensor is inside the outer diameter of the sensor vanes.

Gapping to .03" (.76mm)
