alright so i want to change the plugs on my 07 2500 hemi but it appears different from the 1500s as the coil covers both plug locations, thats not the issue getting it off is, i pulled the 2 bolts off and it comes loose, somewhat.

but i can't just pull it off i don't want to just rip it off and damage something.

does anybody have any tips or advice? cause i sure don't want to pay the dealer 350 for plug replacement

any help would be greatly appreciated

thanks

 

Just pull. They have pretty good suction. The newer hemi's (with MDS) have no wires at all, just 8 coil packs covering 2 plugs a piece. I don't believe the 2500's are any different.

thanks for the reply, yah its just one large pack the covers both plugs so only 8 i started to pull but it had a ton of suction so i didn't know if i kept pulling if i'd screw something up. i'll give it another go later. only other question is once the pack is off does it expose the plug or is there a small wire from pack to plug?

 

There is no wire. Once the coil is removed, you can reach the plug. However, they are in there deep, and the threads are long (compared to every other spark plug I've ever seen). I had to use an extension + plug socket just to reach the easy ones.

Joe thanks again, did you use anit seize on the new ones or any di electric grease?

 

Northern Tool sells decent sockets that are a little bit thinner-walled than Craftsman. They fit in there much better.....less headache.

 

Yes, I used both anti-sieze and dielectric grease. 30k miles is a long time for me. It's taken me almost 2 years to put 7k miles on it.
