🔧 Maintenance

Oil Change Interval:

Typically every 10,000 miles or 12 months, whichever comes first (using synthetic oil). Consult manual for specific recommendations.

Transmission Fluid Service:

Jaguar often recommended 'lifetime' fluid, but proactive replacement (e.g., every 60,000-100,000 miles) is highly advised for longevity.

Coolant Replacement:

Every 3-5 years or 30,000-50,000 miles, depending on coolant type and condition.

Brake Fluid Type:

DOT 3 or DOT 4, Low Viscosity (LV) if specified by Jaguar.

Power Steering Fluid:

Jaguar P/N JLM 9518 or equivalent (typically Dexron III/VI compatible synthetic fluid)

Engine Components:

Timing chain tensioners (early 4.0L engines, less common on 4.2L but still possible), Nikasil cylinder liners (early 4.0L, replaced with aluminum liners in later 4.0L and 4.2L), oil leaks from cam cover gaskets and oil cooler seals.

Transmission:

ZF 5HP24 can be sensitive to fluid contamination and heat; regular fluid changes are crucial. Mechatronic unit issues can arise with age.

Electrical:

Canbus network issues, ABS/DSC module failures, headlight leveling system faults.

Suspension:

Worn bushings, ball joints, and shock absorbers due to age and mileage. Adaptive damping system sensors and actuators can fail.

Body And Trim:

Convertible top hydraulic system leaks or motor failure, door lock actuator issues, fading paint on plastic trim.
