How do you change spark plugs on a Jaguar X type?

Answer 1

I have not done the job yet but this is what I am going to do. Remove plastic cover over the engine ( three screws) You then have access to the front three spark plugs ( cylinders 1,3,5) remove the nut which holds down the independent coils and remove the spark plugs, fit new spark plugs and fit coils on the three front cylinders.

Now it gets a little tricky, you will only be able to access number 2 back cylinder so you have to remove the induction manifold (12 bolts I think) to access the back three cylinders (2,3,6,) properly. Then proceed as with the front three spark plugs, refit manifold and plastic cover, job done.

Removing the inlet manifold on Jaguar X-Type

After disconnecting all the plugs and hoses to the inlet manifold (I left the throttle body on the manifold, disconnected the two small heater hoses) remove the two bolts holding the cable harness at the rear, then the single bolt just below the cable harness. This bolt is located lower and to the right hand side (looking at the engine) difficult, DON'T DROP IT)) remove the bolt securing the inlet manifold to the support bracket. (R/H side.) undo the SIX BOLTS (WARNING. These bolts are of various lengths NUMBER THEM SO THEY GO BACK CORRECTLY) remove manifold. (Make sure just tighten the first time round, once all are fitted and tightened then torque them down)

It is advised to change the upper inlet manifold gaskets, there are SIX of them.

To change the Plugs at the front it is necessary to remove the air cleaner box, after removing the two bolts and bracket at top remove the air filter, you will see two screws inside the bottom of the box, remove these, then pull the box in an upward direction.

Refitting is a reversal
