I just bought this (*) and I understand that it is the only workshop manual for the XJ 12 series available. Unfortunately, as the title clearly states, this does not cover the series III latest versions. Is anyone aware of a workshop manual that covers the XJ12 & Double Six series III up to 1992 as some variations were introduced, for example with the A/C R134a gas parts?

Thank you in advance for making your expertise and time available,

Tommaso

Series III V12 owners have always faced a lack of technical/repair info. Whatever the factory offered doesn't seem to be re-published, possibly due to lack of demand.

You might see what JDHT https://www.jaguarheritage.com/ has to offer these days. Years ago they offered a wide variety of re-published technical info on CDs. I have quite a number of these....some are better than others. Some were re-issued with improved content.

In most cases using XJS manuals for engine and driveline work and Series III XJ6 manuals for everything else will generally be sufficient. But there are some Series III features and variations that are different from either of those cars, as you know.

As to the last couple years of Series III V12 production in particular, well, I wouldn't be surprised if Jaguar never published a specific service manual. These were very limited production cars and any unique features and information was probably communicated via supplemental booklets and service bulletins rather than an entire, dedicated service manual.

Let's hear what others have to say. I haven't researched any of this in a number of years. Newer, better information may have surfaced.

you can download free the "everything but the 12 Cylinder engine" Series 3 Factory Shop Manual sections from my website if you don't have them.

Thank you Jose! Unfortunately I can only find XJ6 manuals on your very nice webpage ...

 

Manuals for the Series III XJ6 will be very useful to you as much of what's covered applies perfectly to your 12 cylinder car. Steering, suspension, body, fuel system, most of the electrical, etc

Thanks for your comment about the site. As Doug said, the Series 3 XJ-12 is essentially the same car as the Series 3 XJ-6 except for the engine and transmission.

Body, upholstery. and most electronics are the same in both cars so you can use the Factory shop manual for the XJ-6 for many things.

I have been searching for factory XJ-12 manuals to post in my site but no luck.

I believe there is a Technician's Shop Manual for the Series 3 V12 (1988-1992), a large paper manual issued by Jaguar for Dealers, but not many were printed. Someone must have one.

the Series 3 XJ-6 model was discontinued around 1987 but Jaguar kept building the same body style only with the 12 cylinder engine and renamed it "V12". Not to be confused with the XJ-40 body style built during the same years and which I call the Series 4 XJ that also came with 6 and 12 cylinder engines.

 

Grazie Jose!

I will download everything that is not specific to the engine as I imagine that cooling, ignition, etc will all be different. Again, thank you! It is always very useful to encounter private websites as, in general, they tend to grow and offer useful information. Like yours!
