HINT:
Perform "Inspection After Repairs" after replacing the engine coolant temperature sensor (LandCruiser RM000004NJC03XX.html).

  1. Install a new gasket to the engine coolant temperature sensor.

  1. Using a 19 mm deep socket wrench, install the engine coolant temperature sensor.

    Torque:
    20 N*m{200 kgf*cm, 14 ft.*lbf}

  1. Connect the engine coolant temperature sensor connector.



2. INSTALL INTAKE MANIFOLD

3. INSPECT FOR COOLANT LEAK
CAUTION:
To avoid being burned, do not remove the radiator cap sub-assembly while the engine and radiator assembly are still hot. Thermal expansion may cause hot engine coolant and steam to blow out from the radiator assembly.

  1. Fill the radiator assembly with coolant and attach a radiator cap tester.

  1. Warm up the engine.

  1. Using the radiator cap tester, increase the pressure inside the radiator assembly to 123 kPa (1.3 kgf/cm2, 18 psi), and then check that the pressure does not drop.
    If the pressure drops, check the hose, radiator assembly and engine water pump assembly for leakage. If no external leakage is found, check the heater core, cylinder block and cylinder head.
