I am replacing the manifold gasket and all the bolts snapped off. So i tore the head off and was wondering what size the bolts are that hold the manifold onto the head. I've called a few parts stores and they don't list them, and the dealer wants $32 for a set of factory studs. Can anyone help me out?
This is on a 3.9L V6 by the way.

 

i dont have the service manual in front of me, but i know that part # and description is there. why dont you call back the dealer who you asked in the first place and ask for the bolt dimensions?

 

The parts guy told me he didnt know the dimensions, only a part # and he could order them, thats it.

 

Well truck is back together and running. Exhaust manifold bolt size is (2) 5/16" coarse x 1", and (2) 5/16" coarse x 2-3/4". Truck runs much better now, but now i get a hesitation and its throwing a code, "TPS sensor malfunction", once i clear the code its fine for another 15-20 miles and it will do it again. The last time it did it I could not use the cruise control. Anyone got any ideas?
