How do you prop off the cables from the coils do you remove the cover?

great job buddy. my truck is turning 160,000km and im doing this job. Is the wire neccesary?

Those plugs are only suppoesd to be like between 11 to maybe 16 lbs of torque, not much more depending.

How much would it cost for thread repair on the 8th cylinder (hard to get to one)? I cross threaded it but shes in there pretty tight. Just sitting at a different angle than the rest of them. Mines a 2014 silver as well.

that adapter is called a Universal look like the Universals on your drive shaft

I removed the wheel cover and never open the hood. Pretty easy

Matco makes a 3/8 the ratchet that is the size of a normal 1/4 inch ratchet. Makes the job simple.

#8 is the trouble child. The rest are doable.

Nice job, I'm going to install mine following your example

I wish I would have known this when you posted this video. That plug now has over 4000 hours or 157000 miles on it... now tomorrow it's getting replaced.

What’s the use of making a video if you’re not gonna show how you took the spark plugs out.

Was your check engine light on ?

Any reason you didn't show pulling plug wires off the coil packs??

Great job! I couldn’t tell you take the tire off as well or just the fender liner?

Great video thanks for sharing

Sergio thanks for the video. Can you drop the link for these in the comments please ? I’m having a hard time finding them online.

Thanks for the tutorial. I learned a lot. I’m doing mine tomorrow.😊

How often do u them

If one or two spark plugs fail it can start the car not?

You can also take the wheel out and removed the trim from around the wheel and it gives you access to all 4 spark plugs

What kind of plugs did you use? Ac delco 41-114?

Why did you go with "34/78" size instead of the "H6", which is the recommended size for all 2014-2018 Chevy Silverado/GMC Sierra 1500? Not only does the H6 have 50 more CCA (800) than the 34/78 (750), it is made to fit in the 2014-2018 GM 1500 trucks, and is the size Optima recommends for them. The H6 also has 140 minutes of reserve capacity (72 AH), whereas the 34/78 only has 120 minutes (55 AH). As far as size, the 34/78 is taller and not as long as the H6, which is why it didn't fit properly and why you had to do all those modifications and buy extra parts. The H6 is already 2+ less in length than the OEM battery size (94R/H7) and the 34/78 is another inch shorter than that. Doesn't make much sense why you went with the 34/78, because the H6 is obviously superior in every way compared to the 34/78 for 2014-2018 GM 1500 trucks. Thanks for posting the install video though, since at this time, Optima doesn't make a direct replacement (94R/H7 size) for the OEM battery. Optima had a press release at the end of 2017 stating it was adding the H7 size to the yellow top lineup, but as of November 2019, it is still not available.

How did you secure the bottom on the battery

Great video I’m trying to do the same with my GMC Yukon very similar set up

What do you do if you need to jumpstart the truck?

Thanks for choosing OPTIMA! Keep your YellowTop fully-charged to ~13.0-13.2 volts whenever possible and it will serve you well
