Hello from France
I would like to change the spark plugs on jaguar xj x351 with the compressor V6

Do you have to remove the compressor to access the spark plugs?

Is there a workshop manual for the xj awd gasoline model 2014?
I tried the forum links but nothing opens
THANKS

 

Hello Paris , you are thinking of ze german invaders , no such thing as a kompresser in any jaguar car only a supercharged unit and no it don't have to come of to replace the spark plugs

 

[QUOTE=George05;2641468]Bonjour Paris, vous pensez à ze envahisseurs allemands, pas de kompresser dans n'importe quelle voiture jaguar seulement une unité suralimentée et non il n'est pas nécessaire de remplacer les bougies d'allumage[/QUOTE
]thank you for the answer and clarification
The spark plugs would last the life of the car?
Currently my car has 115,000 km, so not urgent
Not speaking your language I use the google translator, be indulgent on language mistakes

 

Correct, no need to remove the SC to replace the spark plugs on the AJ126.
But it can be a real pig of a job as there is very little room to move to access the coils and then the plugs, especially the rear plugs.
Also the plastic/rubber covers over each bank are a real bear to replace.
Maybe a little more room and hence easier on an XJ compared to say an XF or F-Type but I doubt it.
Bottom line - not really a job for a first timer better to get it done by someone experienced.

 

No.
Spark plugs are to be replaced at 100,000 miles/150,000 kilometers.
UNLESS you have a diesel engine, which has glow plugs instead of spark plugs.
Check you owner's manual, it's in the service information.

 

thank you for the information
I have the gasoline V6 with the supercharger.
I couldn't find the info in my owner's manual.
Maybe not mentioned in the French edition
