Just did this to my 2002 Silverado 1500. Got it done in about 2 and a half or 3 hours. Followed your video and it worked perfectly, so thank you! Hardest part IMO is taking the wires off the bottom where the spark plug is. I had to use a adjustable wrench and a lot of force to get them off. Spark plug pliers are a must if you want to do with ease.

Truck turns on beautifully now. did this all on my own thank you so much! Very helpful video. Tip: I used a small hose clamp to tighten onto the heat shields and then use pliers to grip into the clamp and wiggle out heat shields without causing damage. Much tougher using hands

[@dalegjerding6954]

To install a sparkplug, I believe it is best to use a rubber fuel line hose to thread the sparkplug in, then tighten it down with a ratchet and socket. This makes it easier to get the plug started, and avoid cross-threading.

[@backyardchevy328]

Yea, that works too..the socket has a rubber insert as well..but yea just gotta make sure to install em by hand to avoid damaging threads

[@vandalsgarage]

I just completed one of these spark plug r&r for a neighbor. My hands are big ol arthritic clubs, so getting into tight spaces is not much fun. I found it to be a whole lot easier to go in through the wheel wells. Takes about ten minutes to remove the wheels and pull back the splash liners, saves a lot of time and you can actually see most of the plugs. In fact, I probably had more trouble with number one than with 8. Do one bank, then start the truck. That way, if you have an issue, you can narrow it down to bank one or two.

[@backyardchevy328]

Good tips👍

[@vandalsgarage]

@@backyardchevy328 By going through the wheel wells, no 8 was not difficult at all. The truck I was working on is a 2004, and the driver side may be a bit tighter than the newer versions. Number 3 give me the most trouble. I didn't have a long-handled flex head ratchet with me, if I ever do this job again, that's a must-have tool.

[@JoeL-re1dc]

A trick I used back in my mechanic days..... push a piece of fuel line onto the spark plug to make a flexible extension to help you get the threads started in those hard to reach and sometimes hot places....

[@shuriKen469]

if i'm not mistaken, that hard one to get to on the passenger side (bank 2) with the plate in the way is slightly more accessible from underneath (5:27). though if it's really stuck on there, i'm not sure what adapters or attachments would be suitable given the lack of space. i was tempted to just remove that shield/plate (4 small bolts?), but i fortunately got the spark plug loose with just a stubby 3/8". cheers for showing that view mate!

@@Native_love thats awesome🙂 well i would recommend swapping the coil from 4 to 2 and vice versa if the misfire switches then its ur coil..then id try checking compression to make sure u got nothing like a valve that may be affecting it..and once u determine thats ok..then id lean towards injector possibly being partially clogged, since it happens under load

[@mikemarler8224]

I just did one of these for a neighbor (pro bono). Had I ever done a spark plug change on the 2nd gen GM SUV, I'd have told him no. lol I found it much, much easier to remove the front wheels and pull back the splash liners. I used an assortment of extensions and u-joints. I don't have a flex head ratchet, probably need to get one. I'm retired, and don't (for a bunch of reasons) take any side jobs for pay. So very rarely do I work on a car that doesn't belong to a direct family member.

I am glad I was changing the wires too because they were on the plugs so tight the ends pulled off the wires. I could not pull them off by hand.

Hey bro, what size gap should I use for my 2002 Chevy Silverado 1500 LS 4.8 ? It says .060 on the manual but the AC Delco plugs I bought are at .050. Yet my engine is very shaky with the check engine light on after the tune up I did. The plugs and wires are new, thanks.

[@backyardchevy328]

They have a new revised gap..because .060 was a little wide..so it was updated to .040..but they do tend to come pregapped at around .044 which is a good gap still. Have u scanned what the check engine light is for? The gap shouldnt cause a misfire if theyre all the same..only if the tip is closed or fouled...i would go around and make sure all the wires clicked in fully into the plugs.

[@raulchavez3856]

Are you Satisfied with the Bosch iridium plugs?

[@alberto_el_tiburon9127]

Can any loose spark plugs or wires cause my engine light to come on??

[@backyardchevy328]

Yea if the wires not clicked in fully itll misfire, the rubber boot will insulate it...loose spark plug can too, if loose enough it may lose compression and also not go in far enough to ignite mixture

What's the best spark plug for the 5.3 ? Your opinion

[@backyardchevy328]

I honestly would go with the original ac delco iridium's ive seen those go over 100k miles and hardly have any issues and theyre not as expensive as other iridium's

AC Delco. They came with the vehicle from the factory.

@@apolloniaaskew9487 if you have an 06 4.8l chevy silverado like I do there is no option for acdelco iridium. There's option for copper, platinum and double but not iridium; however, Bosch is listed as OE double iridium on multiple websites. Iv never changed mine so I don't know

Howdy! Is the gap the same on a 4.8 liter? .040?

[@backyardchevy328]

Hello🙂..yes the gap is .040 for the 4.8L engine as well.

[@AdamSFNews]

Backyard Chevy thanks dude! Changing on my spark plugs this weekend, then my knock sensors the next! Hoping that fixes my problems!

[@backyardchevy328]

@@AdamSFNews thats awesome..hope it all goes well...whats wrong with it?

[@ArmenArmenjs]

what is the recommended mileage for changing the SP?

[@backyardchevy328]

Manual actually recommends at 100,000 miles on the original ac delco plugs, but i change em every 40k-50k. Or if its running rough i like to check one or two of em to see how the plug looks, if u see a lot of carbon definately change em.

What is the gap size for a 4.8 engine

[@backyardchevy328]

Its .040 gap

[@hidalgor1387]

Is this the same with the 2007 chevy avalanche?

[@backyardchevy328]

Yes, itll just have slight differences like the air intake tubing, the engine cover and the heater hoses routed slightly more in the way.

Do I have to disconnect the car battery

[@backyardchevy328]

You dont have to but its always safest to disconnect battery..in case u drop any tools and it contacts starter or if a tool hits on the positive connector and ground...so i would do it to be safest
