Hasta con manga larga se puede hacer…
Sounds good, ill be doing my tune up on my 07 H3 soon I just got her but I rather do it so I can track of my Maitnance on her thanks a lot
You can skip checking the gap distance on the AC Delco Iridium spark plugs. According to the AC Delco website, you should use a gap distance of 0.043″ for the 41-103 plugs with Hummer H3’s.
I have always double checked the gap before installing, never know what happens during shipping. but i’m checking for a big gap difference.
2006-07 and up requires a gap of 1.08 mm 0.042 in
2008-10 and up requires a gap of 1.02 mm 0.040 in
Great video awesome detail, one question I do have is what are the plugs gapped at???
Hi David,
Yes, I had to pull up on the wire harness. There is no vibration.
Hi, excellent video, thanks for posting it. One question: how do you move the wire harness over coil #1? Did you just pry it up off the engine block? I would like to move it without breaking those plastic clips if possible. Thanks.
Glad you liked it. I had fin with it. Thanks for the compliment.
Hey Leafy!
Great, Great, Video! Costs $400 and some dollars to have someone else do it. Thought it was very detailed and consistent. Your video will save people a lot of time..and money.. For new ones, it looks complicated, but you made it easy.. Thanks AGAIN!
