A Word to the Wise
When replacing the number 8 cylinder coil over plug pack (COP)...which is not easy due to the fuel rail, EGR tube and various vacuum lines in the way...DO the following...
- Unplug the electrical socket from the COP
using a 1/4” drive ratchet with 3” extension and a 7 mm socket, loosen the COP attaching bolt
- When ratchet no longer clicks when listening, remove extension from ratchet, place that with the 7 mm socket back on to bolt and finger loosen turn
- Once bolt is out of engine head (bolt no longer moves up while finger loosening)
- Use mechanical fingers, from the side of the bolt and head of bolt, grasp and remove bolt. This ensures you don’t drop the bolt...
- Tilt COP down towards you to remove. Tilting clears the fuel rail.
- Liberally coat COP boot that goes over the plug, with “boot anti sieze grease.
- Using the same way you tilted and removed the COP, install the new COP. As best as you can, rotate the COP down onto the spark plug head. You won’t here a “click” as the boot spring engages the plug head...no worries...just make SURE the distance between the COP and the engine head is almost even.
- Using the mechanical fingers, “grasp” the installation bolt in same position used to remove
- Place bolt over COP mounting hole...ensure tip of bolt goes in the mounting hole and is horizontal to the COP, meaning it’s in the threads of the engine head.
- Use the extension and socket to start the bolt into the engine head...don’t force this. You will strip the threads. Just finger turn the extension and socket until you are sure it’s going in straight.
- When you can no longer finger tighten, put ratchet back on extension.
- Tighten per torque specs for the COP.
- Fire up a smoke and pop a beer open...you’ve earned it!

Anymore comments? I do not respond well to those when I post a mechanical comment. I have probably been turning wrenches and busting knuckles longer than you have been alive 😁. Admins...this reply is NOT a personal attack...just a reply to a smart elect reply.
Not too sure how stating his personal opinion, as you also did, is being a "smart elect"... although I think you mean smart aleck. I tend to agree with MBB here, but if you like your method, have at 'er.
Something any newb can do without instructions
But apparently you consider it a big achievement so congrats to you. Way to go.
Tell us how to change a tire next please, people are struggling with that too.

Well...I see that this forum is a lot like all other truck forums. Ye disrespect posts that actually HELP newbies. Like I replied to the original *** post , I posted THIS TO HELP NEWBIES. Tell ye what, YALL KIN KISS ME ****.
All you did was post a logical common sequence of events to change a single coil.

A (very little) more time to pull two bolts and be able to easily R&R, vs. messing with tilting, turning, using a reach tool, and risking dropping the bolt I to the nether regions of the motor. I know which one I prefer (having done this task several times, and "probably been been turning wrenches" as long as you.) But different strokes.
As for the attitude... Wow.
