EXPERIENCE IN A BOOK

Help for the Jaguar XJ- S owner

by Kirby Palm

Compiled by an XJ-S owner, Experience in a Book is a unique type of automotive resource providing the sort of how-to information not found in either owner's handbooks or repair manuals. The information provided includes maintenance tips, common problems, suggested modifications, and some sources for parts. The book is not intended to replace a repair manual, but rather to complement it.

This is not a small pamphlet; the book is 739 pages when printed with a 10-point proportionally-spaced font, and includes quite a few illustrations and schematics. It grows as more information becomes available.

Experience in a Book may be downloaded, free of charge, from the World Wide Web at:



Yes, you read right: This whole thing is free. If you have a computer, internet access, and a printer, all it costs you is the effort to log on and download plus the paper and ink to print. There are no catches; this is a hobby, not a profit-making enterprise.

This book -- along with a great deal of other Jaguar-related stuff -- is also available on the Nine Lives CD-ROM. There are links to online ordering from the URL provided above, or you can order it directly from:

Coltrane Productions PO Box 932 Morgantown, WV 26507

The cost is $2 plus shipping, and shipping is $0.97 in the US, $1.20 to Canada, $1.66 to Mexico, or $3.40 to the rest of the world.

Experience in a Book is a work in progress and is revised when new information becomes available. If you have learned something about your XJ-S that the rest of us should know, please visit:



and log on to the xj-s@jag- or v12-engine@jag- e-mail discussion lists and post your discoveries there. Most of the contents of this book came from these discussions.

The door locks are electric, so they are discussed under Electrical. However, the handles themselves are discussed under Body.
