I think I read 1 person here has removed their plugs.
But someone posted a link to a procedure..
Now im wondering if the person who did replace-- did you remove the INTAKE MANIFOLD among other things as this states?

I have the HELMS repair manual (I have an 09 Enclave).  You will definitely need to remove the intake manifold to get to the spark plugs in the front bank of cylinders.  The guy that changed his plugs had an 08 (non-DI engine) and the manifold wasn't blocking the plugs so he was able to change them without removing it.

ahh- crap!
Intake manifold-- thats the big metal thing that sits on top of the engine right...
I normally do my own plugs-- but this one sounds like shop/dealer.... unless it just sounds hard.
Im  only at 34K- so a long way from doing this.. but was curious.

Are they even metal on these engines?  The last few cars I've owned since about 2005, have all had plastic intake manifolds. Just curious as well.

I dont know what they are on this engine.
I was under the car giving it my inspection- ramdom....
and so I popped the hood and you can clearly see the Spark plug coils in the rear-
But It looks like space on top of that is limited due to the top portion of the firewall.
I didnt remove the plastic engine cover- but I said to myself... 60K before I have to think of this again.

You could probably even go longer than the 60k miles. I know that's what the manual says, but unless you are having a problem, I would prolong until 100k at least. I just replaced the spark plugs on my truck at 190,000 miles, with no visible signs of wear, and with no engine running change, or fuel mileage change after I replced them. I did replace with OEM direct replacements though, so they were costly, but I figure if they lasted another 190k miles, then I won't ever have to worry about them again.  Happy

Also, you can get to the back spark plugs rather easy on a transverse mounted engine by removing one side of the top motor mount. This will allow you to rock the engine forward, and have more access to the rear spark plugs. An old W body trick.  wink

yeah- thats what I meant- 100K... I already have 34K, so in another 60K or so- ill be near that mark.

Id heard of the rocking the engine forward- never done it myself- Ill have to look around for the engine mounts on the traverse... to see if thats possible.

on the Trailblazer- the inline 6 was easy to replace plugs-- theyre on top.
