A neat trick for threading new plugs in is to slip a piece of vacuum hose over the terminal end of the plug and then use the hose to rotate it and start threading it in. Also I would recommend before doing anything, blow compressed air around the plugs to blast any dirt or debris away that might fall into the hole when the plug comes out.
Awesome video, saved me a lot of time, Thank You!! I did a 2012 LS3, spark plugs and wires in 90 minutes, start to finish going slow per your recommendation on cross threading, I did draw some blood LOL but not too bad. Only 43k miles but a few months ago a wire fell off the coil and a friend suggested changing the wires. Thanks again for a great step by step video..
FYI, I pulled the OEM plugs out of a C6 I bought last summer that had 21K easy miles. One of the iridium tips was GONE! Another one fell off as I was checking the gap. I have heard from others that have encountered this also. Needless to say I will never use an AC Delco iridium plug again. Think about that super hard iridium bouncing around in the combustion chamber! I went with a double platinum plug. It has a bigger center electrode that should be much more resilient to mechanical failure. Again FYI.
@@dennisbarak5195 Not likely. I'm certain they were the OEM plugs and my engine was hand built by GM. My checking the gap was to note how much they had opened up in a mere 21k. I was committed to new plugs from the get go.
You should do the idler pulley, both tensioner pulleys, and both belts! I'm about to dive in next weekend to do the plugs and the belts and tensioners/pulley!
Why don't you use anti seize on the plug threads ?........Also you should put an old towel or blanket on the fenders to prevent any damage to the fender.
Great video. Where both ratches torque ratchets. I didn't know such a thing was made, or was the spark plug socket have a torque setting? If so, what are they called? Thank you.
I had those same Plug wires on mine Good Lord they are hard to get off. Ended up Busting a few of them .Went with the AC Delco Professional Wires So much better to work with..
I'm about to replace spark plugs and wires ... question and sorry it can sound stupid ...do I need to install new heat shields ? Or if the old ones are still good just put them back? I think there is no stupid questions...just Stupids that don't ask lmao 🤣
@@maintainersgarage I will replace wires as my 2005 has the factory ones with 110k miles and reuse the shields ...thanks for responding boss man have a great day
This was also a question I was asking myself, but I was pretty sure I could reuse the old heat shields. For some reason, the boot on cylinder #1 kept coming off, so I'm considering changing all the plugs and wires. The car is nearing the 80k miles mark, so I guess it's already due

Good tips!
That "click-click" torque wrench is the best lol!

You are very welcome!!
Great job, really enjoyed your instruction video thanks
You are very welcome and thank you!
Thank you very informative, probably saved me $150 installation
You are welcome!! Glad I could help! Thank you for the compliment

Thanks for the heads up!
Sounds like someone tried to gap those spark plugs. Iridium plugs should only be gapped at the factory. If the gap is wrong, don't use the plug.

I did the harmonic balancer a year ago and checked the pulleys then and they were good
Thumbs 👍
I was mostly worried about cylinder 7 and whether the brake booster would have to come off. Glad it isn't that involved.
Nope, it's tight, but doable!
Thank you!

No, it is not a torque wrench. I just got snug when i tightened them. Thank you!!
Thx
Thanks for the video, getting ready to do mine. So that was very helpful, did it improve your gas mileage.
I drive like a crazy person so MPG is low on a regular basis
I'M GOING TO HAVE TO WITNESS ALL THOSE TORQUES.
Dan, copy dat! I will go check out a TQ wrench from toolroom and I will send you a call on the call board!!
My G8 has a L76. I wish the clearance was as open as your C6!
I understand. Your engine bay is more cramped as well!
Ohhhh myyyyyy good god!!! 👍
are the channel locks absolutely necessary or could i just do it by hand
Not necessary if you can pull by hand, i could not
@@maintainersgarageI can’t even open it with a channel lock, seems very tight, any recommendations?
@@hosamhassan7721 you saying can't remove spark plug boot from spark plug? If so, try twisting boot with pliers while pulling. They can be very snug

They can be a PITA!
Want to do mine? Lol
Chad, I can supervise if ya need help!! Hahaha
Get what the manufacture recommends. Not what some numb head on the internet thinks.
I can't argue with that.

When in doubt ask questions!
Heat shield is reusable. And plug wires good between 6 years/80k miles or so
@@maintainersgarage thanks brother
You are welcome and good luck 🤞
