What size Helicoil do I need for the crankshaft threads?

Crankshaft Bolt thread/pitch

My crankshaft threads are stripped and I need to know the correct helicoil size for the threads.



Anyone have this information?

um which end of the crankshaft?

The end I'm talking about is towards the front of the car. The place where you screw the crankshaft bolt into

So basically what is the thread pitch on the Crankshaft bolt.

Well you said threads as in plural instead of thread which would have made me thing singular. At any rate take the bolt to the parts store and find a nut that matches it. some parts stores even have a little gadget that allows you to screw bolts into to find out what they are if you dont know. I'd be a little worried about helicoiling a crankshaft but I see you dont have many options at this point. Its not very fine pitch I dont think so your probably looking at a M14 X 1.25. That is a tital GUESS though. I know your looking for an exact answer but unless someone else takes a bolt and finds out for you i dont think anyone knows.
