I have 2003 Dodge Ram 1500 4.7L SLT. Glad to be part of the community. I need a little help.. While taking off my ignition coils I’ve so far broken a couple of the bolts that mount the ignition coils to the cylinder head. I have no idea where to get replacements and I’ve looked just about everywhere I can think of. Unless I can find a replacement I’m stuck to spend $800 from the stealership to get new coils and bolts, they don’t sell them separately I’m told. All I know is at the stealership they call them coil mounting screws (though they look like bolts to me) and the measurements they gave me .375-16 x 1.00

 

Can you get the old bolts out of the intake? Find out what thread they use then get a section of all thread with that thread. Put two nuts together so that a washer and another nut will hold the coil in place.

 

Thank you, yes I have gotten 2 out so far just haven’t gotten to trying the rest yet I’m definitely going to see if I can try that! Just wondering… do the measurements I listed mean anything to you I don’t know what they mean exactly🙈

 

Take one of the bolts you got out of the manifold to the hardware store. Run the part that goes into the manifold into a thread checker. Then get some all thread of that thread. You can cut a section to make a stud for the coil. You'll need several nuts for that thread. Using two nuts, put one about the same section as the washer on your stud. Two nuts together will hold the rod so you can thread it in. Another nut will hold the coil in place. Just be sure to use a grinder to bevel the end so you can thread a nut onto the rod.

 

Moved to the correct section and created a separate thread for this issue.

 

.375 is 3/8 so 3/8 x 16threads per inch, 1 inch long is how i decipher that. however that bolt looks nothing like that, also I would expect it to be metric no sae
but like mentioned above if you can salvage a good one go to the hardware store and match it up. It looks like the isolator sleeve may be removable and used on the next bolt?

 

How did you remove the broken studs? Do you have to remove the intake manifold to do so? I have a 03 Ram 1500 with the 4.7. Eent to do a tune up and found a few of the coils were not secured due to broken studs from previous owner.

 

Hey there! I'm sorry to hear that you're having trouble finding replacements for the bolts that mount your ignition coils. That can be a frustrating situation, especially if you're being told you have to spend a lot of money to get new coils and bolts from the dealership.
Still, you might want to try looking for these bolts at a specialty fastener store or online. You can also try reaching out to the manufacturer or contacting a local auto parts store to see if they can help you locate the bolts you need.
