Yep, pull off the intake pipe, resonator box with I believe 3 bolts and you are there. Take off the bolts to the coil and pull it out and put the new ones in. Hour if your slow.

 

Hour if your slow.

An hour, man that's really slow!

 

All your coil pack is, is un plugging a clip for the wire and then 1 single bolt. Hardest part is taking the intake tub an box off.

I'm assuming the coil pack is the cover that you remove to get to the spark plug, but I'm just very inexperianced at motor work.
Sorry for the extremely novice question.

 

Yes if you give me an hour or so I'll take a picture of it. I have a cai so mine are exposed

 

A note of caution. The torque spec for the coil mount bolt is only 89 INCH pounds. Breaking the bolt would not be a good thing.

 

Once you take the intake off you'll see them. It's really easy man, don't psych your self out.

 

haha I can see them when I open the hood. I have and volant intake that has a very small resonator box and I can see them there.
Just making sure I was on the right page.

 

 

That's them, those stupid clips are the hardest part. Fuckin GM and those safety clips. :lol:

 

Over time I've broken all the safety clips and never replaced them.
I intended to, just never got around to it.

It's hard for me to imagine that connection is gonna came apart (from vibration) without them, even being that its on top of the engine.

 

While I'm in there I think ill swap out my spark plugs too. Yall have a favorite brand etc or does it matter?

 

I have a stack of them in the garage, once they come out I never put them back in. :lol:

 

Bro, some times the spark plugs can be harder to get out than replacing a coil. Used compressed air so debri doesnt fall into the chamber. Once broke loose you can use a fuel hose to thread out and once gapped , use same fuel hose to rethread. Then torque to specs.

 

Gotta love how incredibly simple a plug change is on these engines.

On the other hand, they do seem to be pretty sensitive to plug condition...
Yeah, it'll run fine for many many miles on a set of good irridium plugs, but even after only maybe 40k when you do swap em out you can feel the difference.

I'll take that though, no complaints. I love that crazy little 5-cylinder motor.
Too bad it doesn't idle for shit, but other than that it's F-U-N.

 

Super simple. All you should need it a 10mm ratchet. Take the single bolt out of the plugs after removing the resonator box (if you don't have an intake) and unplug them and drop the new ones in and plug them back up. Easy shmeezy.

 

Yep.

I really wish MSD or someone else with good QC made coil packs for our trucks. I'd pay through the nose for good ones and not look back...all 5 would be gone tomorrow and replaced with new.

 

MSD coils wouldn't be cost effective or much of a gain unless you were boosted.

Shit there is countless LS motors with over 600+ still on factory coils. The coil on plug design is pretty Damn good it its stock form.

Coils are like anything else, they fail with time.....some are better then others. Shit my 2004 3.5 is still on its original coils.

Mine too. I used to run a DIS-4, msd coils and a tuned pcm on my GTP back in the day.

I miss it, that's all

WOW
I am pretty embarrassed at my rookie mistake to bring it to the dealership the first go round.
$138 in parts (2 ignition coils) and I timed myself just for curiosity, 23 minutes and I had the truck back on the road.

Thanks for all your insight guys.
I love this forum
