Land Rover Part Number: PBC500051 - Oil Cooler Assembly
PBC500051 is an Oil Cooler Assembly fitted to AJ Petrol 4.2 V8 Supercharged engines. It transfers heat from engine oil to the engine coolant within the engine lubrication cooling circuit by routing warm oil through internal cooling passages where heat moves into the coolant. That temperature control helps to limit oil viscosity rise under sustained high load and reduces thermal stress on bearings, seals and other lubricated components. This assembly is specified alongside the oil filter circuit; replacement is recommended when corrosion, internal leakage or external damage is present because a compromised cooler can allow coolant and oil to mix or reduce cooling capacity.
