does any one know what oem part number is for the exhaust manifold bolts and studs? I need to replace the exhaust manifold bolts on my 2000 dodge dakota 3.9l (driver side manifold)... Please help.

 

I think they are 3/18"-16 x 2-1/2". I would buy some grade 8 to replace them. Even if you don't want to purchase them from a dealer, give one a call and ask for the part number. You can look them up online after that and find out what they are, then go to a hardware store and pick up some new ones.

 

does anyone know the exact threading and size? i intend on replacing with grade 8 but i want to make sure i get the right ones and the right tap.. i snapped one almost flush. if its metric a want to see if i can tap it in the next closest SAE threading.. any information would be GREATLY appreciated.

 

so i just called a dealership gave them the part number for one of the studs, they gave me these specs for it, 0.312x18 and 2.25"

im assuming the .312x18 is the diamater and pitch, and the 2.25 is the length.

if some one can check my math, i belive the 0.312x18 is 5/16x18..

thank you
