Engine Code:
AJ26, AJ27, AJ28 (V8 variants)
Engine Type:
4.0L V8 (Naturally Aspirated and Supercharged options in later models, though this manual primarily covers NA 4.0L)
Horsepower Range:
Approximately 290-320 hp (depending on specific year and configuration)
Torque Range:
Approximately 290-305 lb-ft (depending on specific year and configuration)
Fuel Delivery:
Multi-point fuel injection
Bore X Stroke:
86 mm x 86 mm (for 4.0L)
Compression Ratio:
10.0:1 (typical for 4.0L NA)
Coolant Capacity:
Approximately 9.5 liters (10.0 US quarts) with the correct coolant/water mixture.
Oil Change:
Typically every 5,000-7,500 miles or 6-12 months, depending on driving conditions (refer to manual for exact specification).
Spark Plugs:
Around 100,000 miles for platinum or iridium plugs (refer to manual for specific type and interval).
Transmission Fluid:
Recommended inspection at 60,000 miles, fluid and filter change typically advised around 100,000 miles or as per manual.
Engine Oil:
SAE 5W-30 or 10W-30 API SJ/SL or higher (check manual for precise grade and quantity, typically around 8.0-8.5 liters).
Coolant:
Jaguar-approved OAT (Organic Acid Technology) coolant (e.g., Ford Premium Coolant or equivalent) mixed with distilled water.
Piston Washers:
Potential for cylinder wall wash on early 4.0L V8 engines (AJ26) leading to oil consumption and potential scoring.
Timing Chain Tensioners:
Early AJ26 engines had plastic timing chain tensioners that could degrade, requiring replacement with updated metal components.
Coil On Plug:
Individual ignition coil failures are common, leading to misfires.
Water Pump:
Water pump failures can occur, often indicated by coolant leaks.
Transmission Leaks:
Leaking transmission cooler lines and seals can be problematic.
