Installing new spark plugs in '03 Montana

[sircarlton]

Does anybody know or have some instructions on how to install new spark plugs in a 2003 Pontiac Montana. I have the 3.4 L V6 engine. I am being told because it is front wheel drive that there is about 3 hours worth of work.

I would like to find out what parts I would need to take out in order for me to install the plugs on the back side of the engine. The car dealership wants $475.00, because the labor is more than the parts.

Thanks
RC

I suggest you buy the Haines Manual. If it's like the 2000 (same engine), you have to rotate the engine forward (which isn't as hard as it sounds). The Haines Manual has all of the instructions. AutoZone sells them for around $15.

It isn't easy, but it isn't impossible either. Should be able to do it on a Saturday afternoon. You'll need a selection of extensions for your ratchet set, and one of those hinged extensions might be helpful, too.

I have replaced the 3 rear spark plugs and #3 was the worst shape even smelled of gas. I replaced all 3 plugs and the problem is still there, itseems to me of a dead cylinder.
any thoughts anyone before i buy a code reader.

#1 - jack the vehicle up and use jack stands to support the van in case jack gives out.
#2 - you can reach up and get the plugs from underneath the van, use a light to shine down on the back of the engines from up top
#3 - the first plug on the left you will need a 3/8 ratchet and spark plug socket
#4 - the middle plug you will need a 3/8 spark plug ratchet and a short extension and spark plug socket and you can get both hands on the ratchet and extension, one hand(arm) on either side of the [COLOR=green! important][COLOR=green! important]exhaust [COLOR=green! important]pipe[/color][/color][/color]
#5 - the plug on the right is a bit difficult but not to hard you will need a 3/8 spark plug ratchet and a spark plug socket. To get the boot off you will need a pair of needle nose visegrips to pull it off as you can't get your hand firmly on it enough.
I have changed all 3 rear plugs in about an hour.
Make sure that you twist the spark plug boot first to break the seal they have with the spark plug, then pull your brains out with a twisting motion.
