Land Rover Part Number: LR036340 - Water Manifold
LR036340 is a Water Manifold fitted to the cooling and heating system. It connects auxiliary circulation and heater hose circuits and routes coolant between the engine cooling circuit, the auxiliary circulation pump and the vehicle heater hoses to ensure correct distribution to the cabin heat exchangers. On vehicles fitted with auxiliary circulation pumps or fuel-fired heaters the manifold provides the connection points used by those components; when installing, match each manifold port to the correct hose or pump feed to maintain intended coolant routing and prevent leaks.
