First id like to say great site and for all the info its provided me. I recently purchased a 92 dakota sport 4x4 3.9 m/t. i purchased it knowing it didnt have any spark and have checked the coil the asd relay and splice and camshaft position sensor. well today i found a problem with the crankshaft position sensor (or lack of one). so the question i have is can anybody give me the info on what size bolts are needed to hold the sensor to the block. thanks 4 any info. GREAT SITE!!!

 

Well I am assuming that you know where the crank angle sensor is located and you will need an allen wrench because the bolts have Allen heads and are about 3 " long. If you bought the truck then look for bolts that will take an 1/4 inch allen wrench. ( Help full you will need an allen wrench about 3 inches long made mine with a drimal and a socket on the moded allen wrench yeah poor mans tools but it works ) Sorry I checked the book no info on bolts sizes but I hope this helps you if your staring at 2 bolts with Allen heads.

 

there are no bolts there the sensor was just hanging by the harness i have located the bolt holes jus seeing if anybody maybe knew the size and tread count so i could maybe go to lowes and pick a couple up after i get a new sensor

 

You can go to the dealer and ask. They can look it up and grab you some too. I had to do that for a few special bolts.

 

Not withstanding length, you should use minimum grade 5 bolts, in 5/16 x18 thread. Typical with TORX head.

 

​​​​I lost one of the mounting bolts for my crank sensor and even the dealer has no information on the specs for this sensor mounting. Did you find anything that fit? I tried the recommended and it didn't fit the hole too large and an M8 was the wrong thread. It's a super unique little bolt that I'm loosing my mind over now

dsg's post is 13 years old so I doubt he'll respond but maybe someone else will or start a new thread might be better.

 

IDK the thread type but the top is hex key I think its 8mm. I use an extended hex for a ratchet from HF and another extension.
