Replace spark plugs and wires, doing #8 the harder way, and then the hard way on a 2013 Escalade 6.2L

I solved the #8 Plug access issue permanently. I don't need rear heat on my machine, so I got rid of the rear coolant lines and heat shield. Instant easy access now! And made my machine more reliable, by eliminating a bunch of coolant leak failure points.

I did spark plugs for the first time ever at the beginning of the summer when my NBS Denali rolled 150k. At 100k I had a buddy do it over at the jeep shop he works for as I just didn’t have the time. This time around though I was like I gotta handle this myself. Surprisingly on the NBS the #8 plug was not the worst plug to do. I did it first and handled it quite easily. The #1 and #3 plugs gave me more of a hassle as there right below the alternator and bracket, which is also where I mounted my catch can. A few swear words were dropped while swapping those ones out.... lol. But it’s a good sense of accomplishment to get the spark plugs changed out. When I finished the job and started the truck up and took it for a spin, I was like yeah this is a good feeling!

I had the dealer do mine. Pricey but worth it. I saved $ by replacing my own Air shocks and air compressor. That was fun.....NOT

I didn't find that job to be too bad, thankfully (no rust). Had to do it on both of ours within a month of each other.

I am in the rust belt and the Denali clearly spent time on dirt roads...

Yeah, that would make it miserable.
