How to Change Spark Plugs & Wires on 6.0L Chevy Engine (Step-by-Step Guide) 

#8 is the one that is misfiring, so... Fun. Thanks for the video. I appreciate the time you took. Keep doing everything for His glory.

I had a few sharks posing as mechanics convinced me to throw parts at my Yukon Denali. They overlooked bad spark plugs and went straight for fuel injectors, throttle body and sensor, MAF sensor and ignition coils. After all of that I was still getting misfire codes on cylinder 6, and I took it upon myself to swap the plug and wire on 6 and wala I’m running like a champ... I appreciate you online mechanics, you guys are doing God’s work with these tutorials and walk throughs. Thanks

Thanks bud, tutorial was very easy to follow along with.

Thank you so much for this. The passenger rear plug kept me from doing this for a long time. But your video was so helpful - that I just did it and it turned out great!

I like to blow each plug hole out with compressed air prior to removing the plug. This will get rid of any sand/dust that could find it's way into the cylinder

Thank you. Cost me $9.76 Sparkplug+grease. I disconnected my battery not sure if that was necessary but it was recommended. Replaced the sparkplug for cylinder 7. Truck runs great again. Appreciate this video!

Thank you for your time and effort making this video, You did a great job with the instruction . American Iron all the way!

- Spark plug boot tool useful to prevent damage from pliers. - Thread length looked different on new plugs? - I would not trust pre-gapped plugs due to shipping, dropping & returns.Can gently check with gap tool.

Best video by far!

Passenger side is easier to get if you remove the front tire. Direct access to the 2 rear plugs

Was just asking a buddy this morning about using any kind of lube on replacement spark plugs for my 6.0 GM boat motors...helpful tip on this subject, thank!

Just picked up a 2011 Silverado 3500 6.0 at auction with 170k. Truck runs good no codes, had it serviced ( oil& multipoint inspection) at local dealership no issues found also I changed air filter. All that being said and not knowing the history on the truck (one of the downsides to buying auction rigs) I'm thinking at a minimum plugs and wires, question would be with these miles do the coils as well or wait?

Great video as well as good info from comment help !! Thanks!!

Hey, so the manual says to use ACDelco 41-962, but some people say to use ACDelco 41-110. I've been using the 41-110 and I've had to change the knock sensor three times already. The engine light is still on. What do you think I should do?

Thank you for your help. God bless you sir

2:30 dam a squirrel. That has to be a rare thing. He had to hungry haha

Is there any downside to still putting some dielectric grease on there just in case?

Thank you!
