Alternator YLE500390 for LR3 L319 Range Rover Sport L320 Range Rover L322 4.4 4.2 V8 petrol/gas
When your alternator fails on an LR3, Range Rover Sport L320, or Range Rover L322, the symptoms can escalate quickly. A flickering battery warning light, an overworked cooling fan running at full speed for no apparent reason, dimming headlights, and eventually a dead battery are all signs that the charging system has given up. This is one of the more commonly reported failure points on these platforms once mileage climbs, and getting the right replacement unit in quickly is the priority. This alternator assembly, part number YLE500390, is the correct direct-fit replacement for all 4.4-liter and 4.2-liter supercharged V8-equipped models in the LR3, Range Rover Sport L320, and Range Rover L322 lineup from 2006 to 2009.
The alternator is a 150-amp unit engineered to handle the substantial electrical demands of these Rovers. The 4.4-liter AJ-V8 and 4.2-liter supercharged AJ-V8 are both Jaguar-sourced engines, and the alternator fitted to these variants is specific to that engine family. It is not interchangeable with the earlier L322 models that used the BMW-sourced 4.4-liter M62 V8, so verifying your engine type before ordering is important. If your Rover was built from 2006 onward with either the naturally aspirated 4.4-liter AJ-V8 or the 4.2-liter supercharged AJ-V8, this is the correct unit. It mounts directly to the factory bracket, connects to the factory wiring harness without modification, and restores your charging system to factory output specification.
The alternator diode is the most common failure point on these units. When the diode begins to fail it causes an irregular drain on the electrical system that the cooling fan compensates for by running at high speed, which is one of the most reliable early warning signs that the alternator is on its way out rather than the battery itself. Replacing the entire alternator assembly rather than attempting a diode repair is the recommended approach, and this replacement unit ensures your charging system is restored to the correct 150-amp output the factory specification requires.

[FAQ]
Will this alternator fit my Range Rover L322 from 2003 to 2005?
No. This alternator is specific to the Jaguar-sourced AJ-V8 engine family used in the L322 from 2006 onward. Early Range Rover L322 models from 2002 to 2005 used the BMW-sourced 4.4-liter M62 V8 engine, which requires a different alternator. If your L322 was built from 2006 onward with either the 4.4-liter or 4.2-liter supercharged AJ-V8, this is the correct replacement unit.
What are the most common symptoms of alternator failure on these models?
The most reliable early warning sign is the engine cooling fan running loudly at full speed even when the engine is not hot. This happens because the failing alternator diode creates an irregular electrical drain that the fan control module misreads as a thermal event. A battery warning light on the dashboard and dimming headlights at idle are also common indicators. If you have recently replaced your battery and it is already struggling to hold a charge, the alternator is the next component to check.
Is this a new unit or a remanufactured unit?
This is a new alternator assembly. It is not a remanufactured or rebuilt unit and carries no core charge. It is a direct-fit replacement that connects to the factory harness and mounts to the factory bracket without modification or adaptation required.
