The bolt came off of my crankshaft pulley whilst driving and I need to get a new bolt. O'Reilly and Advanced Auto don't carry the pulley or the bolt so I was wondering if anyone could tell me the exact dimensions of the bolt. Size, thread pattern, etc. Thanks in advance

 

How does the bolt come off of the pulley whilst driving? You sure the snout didn't break off?

If all you really need is the bolt, call the dealership and order one. You're not going to find it at the hardware store.

 

Take the bolt to your local industrial fasteners place and they will match it with a thread gauge. Then they will either tell you they have a replacement, or dealer is your source. If not from the dealer, get a high-strength bolt only.

 

look down to see if the snout of the crank is still there. if it's gone then you'll need a new crank...which mean you'll probably need a new motor.

 

Wouldn't it be easiest to drop and replace the crankshaft? The VG snouts break between the pulley and sprocket I think.

 

The bolt came loose and fell out i have been talking to him about it and he has explained it to me the snout is there the bolt that holds the pulley in place came loose and got lost

 

Your local Nissan Dealer parts department will be your best bet.

They can look up the part from your description and get you another one ordered. I bet it won't cost too much as long as they have not been discontinued.
