Have just had a code reading done following my previous post; and it is telling me of an ignition problem on #3 cylinder. I'm relieved it appears to be just that - (coil pack or plug apparently). Now, I've look on line to see where is cylinder 3 situated but I keep getting variations..!!! Can anybody help, bearing in mind this is a year 2000, 3 litre model in the UK. Thanks. Geoff H.

 

By convention passenger side of the car is RIGHT,driver's side is LEFT.Using this convention,#3 is on the passenger in the middle,front passenger side is #1 and rear is #5.(Reference:TSB S303-14,p 64 of 70)

 

Pretty close to how I've heard it. I heard left and right are from the driver's perspective. Driver's and passenger's side can change if left or right hand drive. However the driver's pespective of right and left can't change. Unless there's a car where the driver is not facing forward.

The left and right are from the driver's seat. I show the right bank as #1 bank. Bank one are 1,2,3 front to rear and left bank is 2,4,6 front to rear. (ref. illustration #jcfotv6-001 in Alldata.

 

Grab the PDF about Vehicle Specs from the stickies. Has diagram and far more.

 

Cylinder numbering is always a challenge......depends on what document you are looking at and what model year is being considered.

Here's a doc to clarify. You have a 2000 model so #3 will be the rear cylinder on the RH bank as viewed from the front seat.

Good luck!

 

Yes, that's a small part of the info in the PDF I suggested.

 

Ain't that the way it goes; the plug is under the intake manifold.

Curse you Jaguar! (shaking fist)

 

Thanks to all who have offered advice. It does appear that Jaguar/Ford change things more times than the Irish weather..!!! Even the PDF link sent shows a variety of difference configurations. It also appears we have have different ways of viewing an engine. Here in Ireland/UK we view the block from the front of the car, whilst it appears in the USA it is viewed from the cockpit..!!! Having spoken to a guy who has worked on these, it seems MY number 3 cylinder (being a year 2000 European model) is the one nearest the bulkhead on the RIGHT hand side, viewing from the front of the car; which does make it much easier to inspect not having to remove the inlet manifold. Thanks again to you all...(y)

 

Your guy is incorrect. If you'd like proof, let the engine idle and disconnect that rear coil for several seconds. Then have your codes read again and see what number COIL fault you have induced. It won't be number three.

Good luck!

That may be the Irish configuration.

The configuration is universally viewed from the drivers perspective.

The pdf provided by xjrguy indicates the same thing I saw on my information systems. That's 3 differrent sources showing #3 as, bank 1, third cylinder from front of engine.

Another rule is that #1 cylinder is the front most cylinder. I you look at the engine, you'll see that one head is slightly closer to the front (pulley end) of the engine. That cylinder is number one. The bank with #1 cylinder is Bank 1 or Bank A.

The way manufacturers number the rest of the cylinders can vary. On a V6 like the one in question, the possibilities are odd cylinders on one side and even on the other or 1,2,3 on bank 1 front to back and 4,5,6 on bank 2. This is where information systems help you get to the answer.

A test like xjrguy suggested is a good tip to confirm what the information systems are telling us.

I hope you find your answer soon.

 

There's an International standard which Jaguar now follow. They changed from their own (I guess randomly-chosen before I was born) way of doing it. That's why the PDF shows more than one, depending on year of car. Brutal is correct (hardly a surprise).

(I believe the standard makes bank 1 the right (in the sense of RHD / LHD) and cyl 1 is always at the front of bank 1.)
