Needing to replace the crank sensor on my 99 2500 . Not my everyday truck , so I ve been putting it off not knowing what to expect . I ve got to do it in the parking lot where I have it parked and was worried about not getting it finished in time as to not leave it disassembled onernite .

Is this a big job ? I know the starter needs to be dropped , do I need a forklift for the desiel starter . Are any special tools required ? Any help would be useful , thanks , Charlie

 

Here is what I got from Alldata, sorry no pic's.
REMOVAL

Crankshaft Position Sensor (CKP) Location





The CKP is located on the left/rear side of engine block near the starter motor.



Disconnect both negative battery cables at both batteries.
Remove starter motor. Refer to Starter.
Disconnect electrical connector at CKP.
Remove CKP mounting bolt and hold down bracket.
Pull CKP from engine block with a slight twisting action.
CKP Removal/Installation







Discard old CKP O-ring.
INSTALLATION

Only thing I could add to the above is iirc the starter needs 12 point wrench or sockets to get the bolts out.

 

Thanks Dude , sounds pretty simple and sraight forward .

 

Wow that is a good point to bring to attention , and its probably all metric to boot . Thanks

 

Yep, 10 MM.

I bought a cheap NAPA wrench and made an extension out of 1/2" rod for it to get better leverage. ( cut the open end part off, drilled the rod down 1-1/2", shoved the wrench in and flattened it )

Some 10 MM 3/8" drive 12 point sockets would be good to have as well.

 

I used a small jack on the 10 MM wrench to get leverage when I changed contacts in my solenoid. Didn't need the jack the next month when I changed the CKP. Check your solenoid contacts while you have it off. It may save you a starter R&R.
