The manual covers both the '6' (XJ6) and '12' (XJ12) variants. This includes the Jaguar XK inline-six engine (variants like 4.2L and 3.6L) and the Jaguar V12 engine (5.3L and 6.0L). Specific engine codes (e.g., XJ6: AJ6, XJ12: V12 HE) would be detailed.

Performance:

Horsepower and torque figures varied significantly by year and engine configuration, but typically ranged from approximately 170-225 hp for the inline-six and 244-318 hp for the V12. Torque figures would also be detailed in the manual.

Fuel System:

Covered in detail, including fuel injection systems (Lucas/Bosch) for later models and carburetion for earlier ones, fuel pump testing, fuel filter replacement, injector diagnostics, and fuel pressure specifications. Vacuum diagrams are specifically mentioned, critical for fuel and emission systems.

🔧 Transmission

Standard:

Automatic transmissions were standard on most XJ12 models and common on XJ6 models. The ZF 3HP22 and later ZF 4HP24 automatic transmissions are likely covered, along with manual transmissions (e.g., Borg Warner, Getrag) on some XJ6 variants.

Optional:

Manual transmissions were optional on many XJ6 models, providing a sportier driving experience. The specific type and availability would be covered.

Features:

The manual details transmission removal, installation, and in-car servicing. This includes fluid type and capacity specifications, seal replacement, clutch adjustments (for manuals), torque converter checks, and internal component diagnostics.

📐 Dimensions

Exterior:

Jaguar XJ sedans are known for their substantial, long-wheelbase dimensions, offering ample interior space. Exact exterior dimensions (length, width, height, wheelbase) would be listed per specific model year and body style (standard vs. long wheelbase).

Interior:

Luxurious and spacious, reflecting their luxury sedan positioning. Front and rear legroom, headroom, and shoulder room figures would be part of the detailed specifications.

Cargo:

Trunk capacity figures would be provided, typically sufficient for luggage but not class-leading compared to some contemporary rivals due to packaging of drivetrain components and fuel tanks.

Weights:

Curb weights for XJ sedans, especially V12 models, were substantial, often exceeding 4,000 lbs. Gross Vehicle Weight Ratings (GVWR) and axle load capacities would also be detailed.
