Land Rover Part Number: LR005765 - Thermostat Assembly - 4.2 Petrol V8 Supercharged & 4.4 AJ Petrol V8
LR005765 is a thermostat assembly for 4.2 Petrol V8 Supercharged and 4.4 AJ Petrol V8 engines. Fitted into the engine cooling system, this assembly regulates coolant flow and engine operating temperature by modulating routing between the engine and radiator. It restricts flow when the engine is cold to allow rapid warm-up and opens as temperature rises to route coolant through the radiator and maintain normal operating range. This design is specified for V8 petrol applications where higher coolant flow rates and operating temperatures require a matched valve and housing. Replacement of a failed LR005765 restores temperature regulation and prevents temperature-related engine performance faults; it replaces part numbers 4362512 and PCP500050.
