Recommended every 30,000 miles or as needed based on driving conditions.
Spark Plug Replacement:
Varies by engine; V8 models typically at 100,000 miles (iridium plugs). Refer to manual for specifics.
Transmission Fluid Change:
ZF recommends fluid and filter change approximately every 60,000-80,000 miles for optimal performance. Refer to manual.
Engine Oil Type:
Refer to manual for specific viscosity (e.g., 5W-30 or 0W-40) meeting Jaguar's specifications (e.g., Ford WSS-M2C913-A/B or WSS-M2C913-C). Typically synthetic.
Coolant Type:
Jaguar specified long-life coolant (often a pink or orange ethylene glycol based coolant).
Brake Fluid Type:
DOT 4 or DOT 4 Plus.
Air Suspension Leaks:
Common issue involves air springs, compressor, or valve blocks developing leaks over time. Manual covers diagnosis and repair.
Water Pump Failure:
Water pumps can be a point of failure, especially on the V8 engines. Manual details replacement procedures.
Timing Chain Tensioners:
Some V8 engines (especially earlier variants of the AJ-V8) had issues with timing chain tensioners. While the X350 is generally improved, the manual details correct inspection and replacement.
Aluminum Corrosion:
Due to extensive aluminum use, galvanic corrosion can occur at dissimilar metal interfaces. Manual provides guidance on prevention and repair.
Jaguar Legacy:
Jaguar has a long-standing reputation for luxury, performance, and elegant design, tracing its roots back to the 1920s.
Xj Lineage:
The XJ represents Jaguar's flagship luxury sedan, with a history dating back to the Series I XJ introduced in 1968. The X350 (2003-2010) was a significant redesign featuring the aforementioned aluminum construction.
