Hello all. Searched the forums, google and youtube and can't seem to find a good solid answer. My girlfriend has a 2007 G6 with the 3.5. This of course means that three of the plugs are in a wonderful (sarcasm) place behind the engine. I managed to find a video on how to get to the front ones which seems pretty simply. But what about the rear ones? Looking to take apart the least amount of stuff as possible as this isn't my car haha.

I am sure this has been posted here plenty before so I am sorry to be "that guy" and asking all over again. Thanks though guys. Also, new to the site and so far I like what I see! :)

I have a 2006 3.5 so might not be totally similar, but I took off the coil pack and the coil pack bracket. I also took off the alternator and was able to easily get at them all from the passengers side of the engine bay, just have to climb on top of it a little...

Alright. I own a Ford Escort and have only ever worked on it haha. Is removing those two things a cake walk?

I haven't touched the plugs on my G6 yet, but you may find it easier to remove the wiper cowl to gain access. It is a bit of a reach. Gotta love these transversely mounted engines!

I have a 2008 with a 3.5 and let me tell you, they are not as hard as you think. You need an extension or two and a swivel and your good to go. Make sure the engine is not really hot when you do it. The engine warm will make removal easier for you. And make sure to thread them on by hand. But i did mine in like 20 minutes for the back 3 the first time i did it.

Yeah, taking a further look at it, it didn't look impossible. I will take a look at one of the front ones first to see if they even need it. Looks like all I may need to buy would be a swivel.

Me and my brother did it in the driveway in about an hour for all 6 plugs, and wires. It was a bit of a contortionist scene to watch I'm sure but we did it with 2 extensions and a swivel.

Ref: 2007 Pontiac GT G6 Hardtop convertible. I managed to remove/replace my front 3 spark plugs... I ran through the posts here about removing the 3 rear plugs. I have been procrastinating because I really don't want to remove the alternator (absolutely, I am wining) as I really don't see that as being much help. I know a lot of women are strong, but I'm lacking a bit in that department so I have to improvise with additional tools or other (i.e. a man) to compensate. I found a video on you tube the other day (and of course no longer can find) about removing the motor mount bolts and pulling the engine forward with straps like the ones you tie down furniture or other with??? Any thoughts on this method?

using straps is more for like the 3800 series 2 motor cause they have motor mounts on top in the front above the radiator. Your best bet is literally just to snake your arm back there. that or pay someone else to do it.

So my husband trying to change out the spark plug wires for the 2008 G6 GT didn't pay attention to the fact the new wires has no numbering on it. How can he check to see if he placed them in the right order? Is there a video because I am having a hard time finding a video on this. Can someone please help?

I have changed the rear plugs a couple of times. Two tricks:

1. You need just the right length of socket extension. I use in a short one which is shorter than the normal first extension, about two inches.
2. Not essential but hugely helpful, I use a 3/8 ratchet wrench that turns by twisting the handle. It means even the tiniest movement of a degree or two can be fully utilized and, once the plug is loosened, it is rapidly removed by twisting the handle back and forth?

Absolutely no need to remove components to do the job, just contort a bit, reach over and feel your way.

The Coil bank the plug wires plug into can be removed.
Its only a couple bolts and it makes back spark plug access much easier.
