      Install the engine water pump assembly to the timing chain cover with the 5 bolts.

      Torque:
      Bolt A
      26 N*m  { 260 kgf*cm, 19 ft.*lbf }
      Bolt B
      21 N*m  { 214 kgf*cm, 15 ft.*lbf }
      Bolt Length
      Item Length
      Bolt A 35 mm (1.38 in.)
      Bolt B 18 mm (0.709 in.)

    3. Connect the connector to the engine water pump assembly.

  2. ADD COOLANT (for Engine)


    1. Tighten the radiator drain cock plug.

    2. Tighten the cylinder block drain cock plug.

      Torque:
      13 N*m  { 130 kgf*cm, 9 ft.*lbf }

    3. Remove the reservoir tank cap.

    4. Connect the hose to the air release valve.

    5. Loosen the air release valve.

    6. Add TOYOTA Super Long Life Coolant (SLLC) to the reservoir tank filler opening until coolant overflows from the air release valve. Then tighten the air release valve.

      Standard Capacity
      Item Capacity
      Engine coolant

      w/ Exhaust Heat Recirculation System:

      7.2 liters (7.6 US qts, 6.3 lmp. qts)

      w/o Exhaust Heat Recirculation System:

      6.5 liters (6.8 US qts, 5.7 lmp. qts)

      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.

      Note

      Never use water as a substitute for engine coolant.

    7. Disconnect the hose from the air release valve.

      *1 B Line

      Add coolant to B line of the reservoir tank.

    9. Squeeze the inlet and outlet radiator hoses several times by hand, and then check the level of the coolant.

      If the coolant level is low, add coolant.

    10. Put the engine in inspection mode Click here.

    11. Install the reservoir tank cap and air release valve, and warm up the engine sufficiently.

    12. Bleed air from the cooling system.

      Note


      • Before starting the engine, turn the A/C switch off.

      • Adjust the heater control to the maximum hot setting.

      • Adjust the blower speed to low setting.


      1. Warm up the engine until the thermostat opens. While the thermostat is open, allow the coolant to circulate for several minutes.

        Tech Tips

        The thermostat opening timing can be confirmed by squeezing the inlet radiator hose by hand, and sensing vibrations when the engine coolant starts to flow inside the hose.

        CAUTION:

        When squeezing the radiator hose:

        • Wear protective gloves.

        • Be careful as the radiator hoses are hot.

        • Keep your hands away from the radiator fan.

      2. Squeeze the inlet and outlet radiator hoses several times by hand to bleed air from the system.

        CAUTION:

        When squeezing the radiator hose:

        • Wear protective gloves.

        • Be careful as the radiator hoses are hot.

        • Keep your hands away from the radiator fan.

      *1 Full Line
      *2 Low Line

      After the engine has cooled down, check that the coolant level is between full and low.

      If the coolant level is low, add coolant to the full line on the reservoir tank.

  3. INSPECT FOR COOLANT LEAK (for Engine)

    CAUTION:

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

    Note

    Before performing each inspection, turn the A/C switch off.


    1. Remove the reservoir tank cap.

    2. A01JB8R

      Fill the radiator and reservoir with coolant, and then attach a radiator cap tester.

    3. Put the engine in inspection mode Click here.

    4. Warm up the engine.

    5. Using the reservoir cap tester, increase the pressure inside the radiator to 108 kPa (1.1 kgf/cm2, 16 psi), and check that the pressure does not drop. If the pressure drops, check the hoses, radiator, front exhaust pipe assembly and the heater hose around and engine water pump assembly for leaks. If no external leaks are found, check the heater core, cylinder block and cylinder head.

    6. Remove the radiator cap tester.

    7. Install the reservoir tank cap.

  4. INSTALL INLET AIR CLEANER ASSEMBLY


    1. A01JBG6

      Install the inlet air cleaner assembly with the 3 bolts.

      Torque:
      7.0 N*m  { 71 kgf*cm, 62 in.*lbf }

    2. Connect the wire harness clamp to the inlet air cleaner assembly.

    3. Connect the No. 4 water by-pass hose to the inlet air cleaner assembly with the clamp.

  5. INSTALL ENGINE UNDER COVER

  6. INSTALL FRONT SPOILER COVER (w/ Front Spoiler)
