The water pump circulates coolant through the engine block, cylinder heads, and radiator to maintain operating temperature on Land Rover's 4.4 AJ-V8 and 4.2 supercharged V8 petrol engines. On these engines, water pump failure typically presents as coolant leaks from the pump weep hole, overheating under load, or bearing noise from the front of the engine. Replacing with the correct OEM-specification pump ensures proper flow rate and seal compatibility with the original housing.
