Hi Guys
Can anyone advise me on how difficult it is to change the spark plugs and pencil coils on my 2002 3 litre X- type . Looking under the bonnet and taking off the engine covers I cant even see them .

 

Phill,

Check this link for procedure with pics:

Engines may look tidier nowadays with all the covers but it certainly makes things harder to find!

phill54, replacing plugs is not difficult, but it isn't a 30 minute job like it was on older cars. You will have to separate the top half of the intake from the engine, remove the air box from the car. From there, it is pretty straight forward. The big thing with the intake is there are 4 hidden bolts (all 10 mm) that you have to remove before the intake will be able to be rotated. There's 2 against the firewall, 2 in the opening between the intake and the throttlebody.

 

it is relatively easy to change them, but unlike most cars, a lot of equipment needs to be removed to access them, they are truly "buried" in the engine.

Following the various step by step posts on here is essential for first time removal. Don't even try without reading up on here how to do it. I don't think it is even possible unless you know all the steps and what to remove....BUT, like i said, it is quite easy when you know how, it takes about an hour to complete the job

 

I recently changed the plugs... took me around three hours... go to google and search "jaguar project sparks". You will find a specific detail article. Read it and if you understand it go for it. If not, better to someone else to do it for you.
