I am new to the Jaguar world and am either trying to find a link to good manual or the procedure for changing the spark plugs on an 02 X type 2.5L V6.

 

I always take a look at this guide, it has everything you need to know.

Hank, do a search here for "JTIS". That is the service manual for your car plus some other jags. But, that will answer just about any question that you have. it is a free download on the main X-TYpe page.

 

I would highly recommend getting the intake gaskets while you're there. If they're the old (most likely original) gaskets, they rarely seal correctly after putting it all back together, can cause a misfire or stumble when cold.
