Depth:
Comprehensive, covering everything from basic scheduled maintenance to full engine and transmission rebuilds. Includes detailed diagnostic procedures.
Crash Test Results:
While official NHTSA/Euro NCAP ratings for these specific years and models are less readily available than modern vehicles, the X100 was designed with a focus on occupant safety, featuring a robust structure.
ABS:
Standard Anti-lock Braking System (ABS)
TCS:
Standard Traction Control System (TCS)
Airbags:
Front airbags, side airbags (depending on trim/year).
Seatbelts:
Pyrotechnic pretensioners for front seat belts.
Oil Change:
Every 10,000 miles or 12 months, whichever comes first.
Transmission Fluid Change:
Recommended every 60,000 miles or 48 months. The manual will detail the specific procedure.
Coolant Change:
Initial change at 150,000 miles, then every 30,000 miles or 24 months.
Engine Oil:
SAE 5W-30 or 5W-40 synthetic oil, meeting Jaguar engine oil specification (e.g., JLM 20302 or similar).
Coolant:
Jaguar Antifreeze/Coolant (Ethylene Glycol based, Orange/Pink color, Jaguar specification).
Brake Fluid:
DOT 4 (or DOT 4 LV for vehicles with specific stability control systems).
Timing Chain Tensioners:
Early AJ-V8 engines (pre-2002 approx.) are known for potential failure of plastic timing chain tensioners, which can lead to catastrophic engine damage. This manual will detail inspection and replacement procedures for these critical components.
Spark Plugs:
The 4.0L V8 uses single-piece spark plugs. While generally reliable, premature failure or improper installation can cause issues. The manual provides torque specifications and installation guidance.
Coil On Plug:
Individual ignition coils (Coil-On-Plug) can fail, leading to misfires. The manual details diagnostic procedures to identify faulty coils.
Nikasil Liners:
Early 4.0L engines (pre-1999 approx.) with Nikasil cylinder liners can be susceptible to damage from high-sulfur fuels. Later models used aluminum liners. The manual may cover identification and specific considerations.
