Hi, new here. I just bought an 89 Dodge Ram w250. It is gas with v8 5.9l 360. Realized I have three broken exhaust manifold bolts. I want to order gaskets and bolts so that I can start process of getting all old bolts out. I'm not having luck searching. I can find gaskets and manifolds but not the bolts. Hoping that I don't have to call a dealer cause it seems like they aren't interested in these issues. Anyone else replace these before and if so where did you source your bolts. Thank you.

Any automotive store should have them. Make sure you get grade 8's.

 

Ok I get the grade 8 thing cause that has to do with bolt strentgh. What i am not sure about is finding the right length and diameter and thread pitch. I don't want to strip out that head. And am assuming that the rest are going to break. I don't want to strip head although I have been researching how that comes out to.
I am hoping that someone knows where to get those bolts so i can just order a bag of them. That might not be an option.

 

yes you can just call your local auto parts store and they will order for you 1 hr.

 

You can get the complete set at Mancini racing.com.
About 50 dollars..

 

The ones on my truck were also broken. The end of the manifolds actually use studs and brass nuts. Bolts are used on the rest. The trick is getting the broken ones out of the head. Had to drill mine out. Regular grade 8's will work if you can't find the factory ones.

 

I know I have been doing some research on how to get those out of there. Think I got a good idea on it. Trying to figure out when I am going to do the job bc if I can't get bolts out I am going to have to remove head. One shop told me it could be up to 2100. Since they didn't know what the work would be. I have taught myself some things over the last 10 yrs so I probably going to diy

 

I was noticing the stud thing too went through and drew out a diagram of what was stud and what was bolt. Looks like they use a really skinny stud on middle drivers side where that heat shield fastens.

Did you have to actually drill the bolt with ascending size bits? That sounds nerve bending. I'm hoping I got something sticking out of the head when the manifold comes off.

 

The trick to getting out broken fasteners is center punching the broken bolt dead center . I use a small bit 1/16 then go up from there. Best to use left handed drill bits if your drill will run in reverse. Sometimes the bit will grab the fastener and spin it out while being drilled. If it is rusted use lots of high quality penetrating oil. There is a product called PB Blaster that I like that works well. I have accidentally drilled off center and was able to use a tap to re-thread the hole afterwards. I want to say the holes are 5/16-20 coarse thread.
