Jaguar Plugs

Oct 01, 2005 8 Replies

Okay, its many years since I looked at an engine (I used to do all my own work and used to work on helicopters!!!),



but on a 3.0 litre S Type Jag, where the heck are the spark plugs, and is there anywhere on line I can find a description etc for changing them.



Life is so different now



Many Thanks in Advance


They are under the plastic covers and are placed centrally to the cylinders as are all four valve engines. Aren't they 'maintenance free' iridium plugs with a life of something like

75000 to 100,000 miles?

Thanks huw, luks like a trip to the dealers after all!!

It should be fairly easy to get the plastic cowling off, even if it means using Allen keys or those starry type things. The plugs will be deep down central tunnels and will need a socket designed to grip and lift them out. Quite basic these days.

They may well be seperate coils as well, in which case you won't find any plug leads under the cover. There'll be six (assuming it's a V6) seperate modules. Each one has to be unbolted to gain access to the plug below.

Whatever the Mondeo V6 has, it is likely that the Jaguar will be similar.

Umm, Nigel...

If you can't get to the plugs, then you CERTAINLY won't be able to do the rest of the maintenance that the car will need at that high a mileage and large a service.

They have individual coil packs that sit on top of the plug on a long snout. The whole lot will be hidden under a plastic cover on the top of the head - just undo the screws that look like they hold the cambox cover on and a plastic plate comes off with the coil packs and the top of the real cambox cover then being visible.

Just been reading this month's car mechanics. It seems that the S type V6 has long life plugs that only need replacing every 70k. However, once it becomes necessary to replace them, you have to remove the inlet manifold to gain access! So there's a little more work involved than one would normally assume!
