Hi guys. Merry Christmas to you all.

I've read and re-read the guide below about how to change the spark plugs.....

http://www.omegaowners.com/forum/index.php?topic=90536.0

..... however, my car is a 2.5 v6 and as I've never done this before I'm a but confused about what ''extras'' I need to do in addition to the guide for 2.6/3.2 spark plug changes. Can anyone advise?

Thanks

You have to remove the individual lead from each cylinder, the 2.6/3.2's have a single pack which covers each back.

Thats the only difference

Excellent. Cheers mate. Am I correct in thinking that they just pop off to reveal the spark plugs? And that everything else in the guide should be followed? 

[tunnie]

Yes they just pop out, you may find a special plastic 'tool' to help you pull them out. It will be clipped to the top of one of the leads

sorry guys... at what picture number on the guide do i pop the leads off from the plugs??? pic 2? cheers

Picture two shows the coil packs of a drive by wire car being removed, as you don't have coil packs, you will be able to see 3 HT leads. Just pull each HT lead in turn off its spark plug. Leads can be difficult to pull off though, if you're lucky, you'll have a puller clipped to one of the HT leads.

+1.

Thanks for all the help guys as usual.

Presumably the red ''puller'' is the plastic tool that Tunnie was referring to and can be used to pull off each HT lead as they're al tricky?

Also, do I still need to go through all the stuff on the guide i.e. 18 or so steps?

Sorry as I've never done this before I'm just a tad confused. Are we saying when I release each lead I can unscrew plugs directly and won't have to go through all the other steps in the guide?

Cheers folks and cheers RobG for the piccie

The second and third is that with the newer engines being ‘Drive-by-Wire’ and having no mechanical EGR valve, there is basically nothing at all blocking access to the driver-side spark plugs, making it very easy to work on.

The fourth is that on the newer engines the idle speed is ECU-controlled thus no ICV unit, making access easier to the passenger-side spark plugs.

If working on 2.5/3.0, these items will need to be removed to improve access.

you will have to remove these to get access to unscrewing the plugs (not as hard as it sounds)

Thanks Fiend,

So am I to follow steps as follows:

1
Pull HT Leads out (using pulley if it has one... I'm sure it does)
5
6
7
8
9
10
11-16 seems specifically for engines with coilpack

So at what point do I remove EGR and ICV? And have I got this order right?

Sorry if I've got this totally messed up. Just trying to get my head around it

[Andy B]

Thanks Fiend, .....

You don't

[tunnie]

The guide does not suggest that needs to be done?

You just need to remove each lead from each cylinder, that gives you access to un-screw & remove/replace each plug. Then put lead back on.
