Engine Type:
AJ6 (Jaguar Straight-6)
Displacement:
3.2L (3239 cc) and 4.0L (3980 cc) inline-six.
Engine Code Examples:
3.2L: 7P (VIN check recommended), 4.0L: L (VIN check recommended).
Horsepower 3.2L:
Approx. 210-220 hp (varies slightly by market and year).
Torque 3.2L:
Approx. 210-225 lb-ft (varies slightly by market and year).
Horsepower 4.0L:
Approx. 230-245 hp (varies slightly by market and year).
Torque 4.0L:
Approx. 270-285 lb-ft (varies slightly by market and year).
Fuel Delivery:
Electronic Fuel Injection (EFI) - Bosch Motronic system commonly used.
Fuel Type:
Unleaded Premium Gasoline (91 octane or higher recommended).
Cylinder Head:
Dual Overhead Camshaft (DOHC), 4 valves per cylinder.
Construction:
Lightweight aluminium alloy block and cylinder head.
Oil Change Interval:
Typically every 6,000-10,000 miles (10,000-16,000 km) or 12 months, depending on driving conditions. Consult manual for exact Jaguar recommendations.
Transmission Fluid:
Intervals vary; often recommended around 50,000-80,000 miles (80,000-120,000 km) or as per the service schedule. Fluid and filter change is critical.
Engine Oil:
API SG/SH, SAE 10W-30 or 10W-40 recommended for most conditions (refer to manual for specific viscosity grades based on temperature).
Coolant:
Ethylene Glycol based antifreeze/coolant, typically a 50/50 mix with distilled water. Specific Jaguar coolant types are recommended.
Transmission Fluid:
Dexron III / Mercon automatic transmission fluid (ATF) for ZF 4HP22/4HP24 transmissions. Always verify with manual or VIN.
Brake Fluid:
DOT 3 or DOT 4 brake fluid. Always use fresh, sealed fluid.
Head Gasket:
While the AJ6 is robust, head gasket issues can occur with age and mileage. The manual will detail proper diagnostic and repair procedures.
Electrical Gremlins:
Older Jaguars can be prone to minor electrical issues due to aged wiring insulation, connectors, and body control modules. Comprehensive wiring diagrams are essential.
Suspension Components:
Wear and tear on bushings, ball joints, and suspension mounts are common with age. The manual covers inspection and replacement.
Rust:
Common in older vehicles, especially in areas prone to road salt. Underbody and wheel arches are typical areas. The manual may cover minor body panel repair procedures.
