Spark Plug replacement?
 

Spark Plug Replacement?

Ok this may be a stupid question and I guarantee I can figure it out but at the moment I am laid up from knee surgery and still can't move around to well. I did a search and could not find any info.

Does anyone know how to change the plugs on an H3? Is it very accessible? Does any one have pics?

Thanks for any info.

Doc,
I don't have the answer to your question but I did want to wish you well and I hope you're up and around soon.

On top the head you will see the five ignition packs and connector leads..you remove the (I think two) screws holding it down and the spark plug is directly underneath it..you will have to tug on it a bit as it is secured by a compression fitting boot to the top of the sparkplug

CORRECTION:

I see now that they haveone 10MM bolt holding them into place...The 07's are a little different, so I can't speak to them..

Do be careful with the bum knee..I think the H3 is the hardest truck to reach stuff under the hood...I'm 6'3 and I still have to stand on my tippy-toes

I'm only 6' tall! You need to come to Ohio Dennis when I'm ready to change my plugs. :)

Thanks for the pic Dennis looks just like I remembered, but with better detail.Man imagine if we were under six foot. That would suck.

Ok guys and gals. I am changing the plugs for the first time, and just to make sure. I pulled off the intake and it looks as if the plugs are underneath. Just one question. Is that the injectors I see just to the right on the side of the manifold?

That may have been the easiest plug replacement I have ever done, but I did have to reach to get to the back plug (and I am 6'6").
