Depth:
Comprehensive: Covers everything from basic maintenance to complex engine and transmission rebuilds, including detailed diagnostics and wiring.
Oil Change Interval:
Typically every 5,000-7,500 miles or 12 months, whichever comes first (refer to manual for exact specifications based on oil type).
Transmission Fluid Change:
Recommended every 30,000-60,000 miles for the ZF automatic transmission (consult manual for specific intervals and procedures).
Coolant Flush:
Every 30,000-50,000 miles or 2-3 years.
Engine Oil Specification:
Refer to manual for exact viscosity grade (e.g., 5W-30, 10W-40) and API service classification. Often a full synthetic is recommended.
Transmission Fluid Specification:
Jaguar JLM 20242 or ZF LifeguardFluid 5 (or equivalent approved fluid for ZF 5HP24 transmission).
Coolant Specification:
Jaguar Long Life Coolant (Ethylene Glycol based, typically green or orange).
Timing Chain Tensioners:
Early AJ-V8 engines (pre-2001) are known for brittle plastic timing chain tensioners that can fail, leading to catastrophic engine damage. Replacement with upgraded metal tensioners is a critical preventative maintenance item.
Water Pump Seals:
Water pump seals can degrade, leading to coolant leaks.
Nikel-Plated Spark Plug Threads:
Early AJ-V8 engines used nikle-plated spark plug threads which could seize and strip upon removal. Later models used different thread inserts.
Throttle Body Issues:
Electronic throttle bodies can fail, leading to erratic idle or acceleration issues.
Cats (Computer Active Technology Suspension):
Adaptive suspension dampers can leak or fail over time, affecting ride quality and requiring replacement.
