THERMOSTAT INSTALLATION


  1. INSTALL THERMOSTAT


    1. A01CIICE03

      Apply a continuous bead of seal packing (diameter 1.5 to 2.5 mm (0.06 to 0.10 in.)) as shown in the illustration.

      Seal packing
      Toyota Genuine Seal Packing Black, Three Bond 1207B or equivalent.

      Note


      • Remove any oil from the contact surfaces.

      • Install the water pump within 3 minutes of applying the seal packing.

      • Do not start the engine for at least 2 hours after the installation.

    2. A01CI6X

      Install a new gasket onto the thermostat.

    3. Align the jiggle valve to the position shown in the illustration and install the thermostat.

    4. A01CGNU

      Install the water outlet with the 3 bolts.

      Torque:
      29 N*m  { 290 kgf*cm, 21 ft.*lbf }

  2. CONNECT INLET RADIATOR HOSE


    1. A01CJ8P

      Connect the inlet radiator hose with the clamp.

  3. ADD ENGINE COOLANT


    1. Add engine coolant.

      Specified capacity
      14.7 liters (15.5 US qts, 12.9 Imp. qts)

      Note

      Never use water as a substitute for engine coolant.

      Tech Tips


      • TOYOTA vehicles are filled with TOYOTA SLLC at the factory. In order to avoid damage to the engine cooling system and other technical problems, only use TOYOTA SLLC or similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite, non-borate coolant with long-life hybrid organic acid technology (coolant with long-life hybrid organic acid technology is a combination of low phosphates and organic acids).

      • Contact your TOYOTA dealer for further details.

    2. Check the coolant level inside the radiator by squeezing the inlet and outlet radiator hoses several times by hand. If the coolant level goes down, add coolant.

    3. Install the radiator cap sub-assembly.

    4. Slowly pour coolant into the radiator reservoir until it reaches the full line.

    5. Bleed air from the cooling system.


      1. Warm up the engine until the thermostat opens.

        While the thermostat is open, circulate the coolant for several minutes.

      2. Press the inlet and outlet radiator hoses several times by hand to bleed air.

        Note


        • Be careful as the radiator hoses are hot.

        • Keep your hands away from the radiator fan.

    6. Stop the engine and wait until the coolant cools down.

    7. Remove the radiator cap sub-assembly and check the coolant level.

    8. If the coolant level has dropped, add coolant.

    9. Check the coolant level inside the radiator reservoir tank again. If it is below the full level, add coolant.

  4. INSPECT FOR COOLANT LEAK


    1. Remove the radiator cap sub-assembly.

      CAUTION:

      Do not remove the radiator cap sub-assembly while the engine and radiator are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.

    2. A01CIGLE02
      Text in Illustration
      *1 Radiator Cap Tester

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

    3. Warm up the engine.

    4. Using a radiator cap tester, increase the pressure inside the radiator to 137 kPa (1.4 kgf/cm2, 19.9 psi), and check that the pressure does not drop.

      If the pressure drops, check the hoses, radiator and water pump for leaks. If no external leaks are found, check the heater core, cylinder block and cylinder head.

    5. Install the radiator cap sub-assembly.
