Land Rover Part Number: LR122709 - Heater Manifold
LR122709 is a heater manifold that provides the sealed connection between the engine block and the heater inlet hose; where fitted it incorporates the temperature sensor mounting and forms part of the vehicle heating circuit. On 5.0 litre AJ133 V8 petrol applications it routes coolant between the engine and the cabin heater circuit, ensuring flow to the heater core. Correct sealing and secure hose attachment at this manifold prevent coolant loss, maintain heater performance during normal and boosted engine operation, and help ensure correct sensor readings. During replacement, confirm hose routing and sensor mating match the vehicle configuration.
