Iridium spark plugs last about 120,000. If they go out or are going out the coils & wires won’t be far behind. I recommend doing the job in its entirety for best results
@@rhurtadorh32 I agree. This is reason to change the spark plugs early, like 5 to 10K before recommended interval. This way the spark plug gap does not widen enough to stress the coils, and plug wire insulation. If in doubt, do an electrical check on the coils. If they are good, use them.
good job overall. BUT..i alwayd use fender protective covers on a customer car..especially a high end car..you will inevitably scratch or drop a tool on the paint..which would piss me off if it was mine....be professional. 2: using an electric wrench is the quickest way to strip or cross thread...use for taking out only. you shoukd have showed how to get to the right rear...I usually pull the oil stick bracket bolt and move it aside...then it is doable..tight..but doable. 4use a piece of fuel like..3 inches to the top of the plug..and they will find their way back into the holes..and you wont damage if u cross thread bc you cant app too much torque w the rubber...5..if you got a torque wrench on that right rear..youre better than most :) 6 good use of dielectric grease..often overlooked. i give you a "C" bc my mantra is just like the hypocratic oath..First do NO harm. the best skills in the world dont overcome damage to a customers vehicle...otherwise...B+
I use denso plugs made for the 6.2 big mistake oem is the best for this engine now I gotta do it again these suv are highly sensitive must be oem all the way
Glad I read this comment I was definitely gonna use Denso plugs. I use to use them for my 98 F150 and they made it run/sound amazing. Very responsive throttle. What happened when u used them for the Caddy?
🤌🏾🫵🏾If it makes you feel better the old spark plug wires are red the new ones were black at 8:11 you’ll see the new coil and wire so I must’ve changed the back one it’s simply easier on the driver side didn’t want to be redundant
Lol you didn't want to be redundant? So you don't show the hardest one. The reason why most people will watch the video... but you'll be redundant on an the other ones... gotcha@ultimatediyguy395
Hey Man I want to DYI on my 2018 Lade but I haven’t found a Vid to check it out
Bout to do a tune up should I do the coils or leave them alone since they are fine

@@mack606you dont need to change the coils unless there faulty. Wires yes you must changed them.

@@darrenreynolds7985 I used them on 2011 Yukon Denali xl 6.2 misfire and skipping switch to ac delco wires and plugs and everything is smooth
Why didn't you show you doing the last one because you didn't shame on you
