I've only changed the plugs on my HEMI once, I'm coming due soon to replace them, like I said before I do not remember having any trouble changing them... ...I do remember swapping around tools, and I think that was because there was less room for tools on a few of the plugs, but if that is all I remember, than it couldn't have been so tight is much of a problem, other than I had to swap around the tools I'm using to get into the tighter space....Thanks Jim. You are first to mention the degree of difficulty with space on one side. Is it so severe that it incurs a dealer increase in labor cost?
I am a bit skittish about plug removal since I broke my first and only one off at age 14 before I knew there was such a thing as a torque wrench. .
Anyone else on this situation and how to handle?
If you broke a spark plug off it must have been in an iron head, an aluminum head you will strip out the threads... ...read my advice above about using anti-seize or lube with a torque wrench.... ...getting plugs tight is not that critical, especially with crush gaskets that Chrysler/FCA usually uses on their engines (don't know if they're on the V6) you'll get much better results just following the instructions on the box, tighten to finger tight and then 3/4 of a turn with the wrench, when the wrench stops moving with a moderate force on the wrench, you're done.... ...I've never had a plug back out....
What's your question?Thanks for all of the Spark Plug change advice. Now for a change of subject.
I have 2013 Jeep GC Overland w/hemi. Just checked mileage with 110,000 miles on original plugs.
At 60, Adaptive cruise control, GS parkway. 26.1
At 65 " " " " 24.7 minus 1.4 mpg.
A check at 55 might be 27-27.5? .
