Land Rover Part Number: LR124571 - Oil Cooler
LR124571 is an oil cooler used on 3.0 I6 Turbo Petrol (AJ20P6) engines. Fitted into the engine lubrication circuit, the unit cools engine oil and interfaces with the oil filter to maintain correct oil flow and serviceability.
The LR124571 oil cooler reduces engine oil temperature to help preserve oil viscosity and protect bearings, camshafts and other moving components under sustained or high-load turbocharged operation. The unit is positioned in the oil circuit to allow heat transfer to the engine coolant or ambient airflow and is matched to the AJ20P6 engine family to manage thermal load during normal and high-demand driving. Replacement is required where there is evidence of oil overheating, oil/coolant cross-contamination or external leaks. When servicing, confirm correct assembly sequence and use compatible seals and fasteners to prevent leaks and maintain oil pressure integrity.
