THERMOSTAT INSTALLATION


  1. INSTALL THERMOSTAT


    1. Install a new gasket to the thermostat.

    2. A00OUG3E01

      Install the thermostat with the jiggle valve facing upward.

      Tech Tips

      The jiggle valve may be set to within 10° on either side of the prescribed position.

  2. INSTALL WATER INLET


    1. Install the water inlet with the 3 bolts.

      Torque:
      11 N*m  { 112 kgf*cm, 8 ft.*lbf }

  3. INSTALL NO. 4 WATER BY-PASS PIPE


    1. A00OTSC

      Apply soapy water to a new O-ring and install it to the by-pass pipe.

    2. Install the No. 4 water by-pass pipe with the bolt.

      Torque:
      11 N*m  { 112 kgf*cm, 8 ft.*lbf }

  4. CONNECT NO. 2 RADIATOR HOSE

  5. CONNECT WATER BY-PASS HOSE


    1. Connect the water by-pass hose.

  6. ADD ENGINE COOLANT


    1. Tighten the radiator drain cock plug by hand.

    2. Tighten the cylinder block drain cock plug.

      Torque:
      for Type A
      13 N*m  { 130 kgf*cm, 9 ft.*lbf }
      for Type B
      25 N*m  { 255 kgf*cm, 18 ft.*lbf }

    3. Add TOYOTA Super Long Life Coolant (SLLC) to the radiator reservoir filler opening.

      Standard Capacity
      Item Specified Condition
      w/o Power Heater 7.4 liters (7.8 US qts, 6.5 Imp. qts)
      w/ Power Heater 7.8 liters (8.2 US qts, 6.9 Imp. 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).

      Note

      Never use water as a substitute for engine coolant.

    4. A00OUQDE01
      Text in Illustration
      *1 Air Release Plug

      Remove the radiator cap and air release plug and add coolant to the B line of the reservoir tank.

    5. 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.

    6. Install the cap and air release plug, and warm up the engine sufficiently.

      Torque:
      2.0 N*m  { 20 kgf*cm, 18 in.*lbf }

    7. Bleed air from the cooling system.

      Note


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

      • Adjust the air conditioning temperature setting to MAX (HOT).

      • Adjust the air conditioning blower setting to Lo.


      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 hoses:

        • Wear protective gloves.

        • Be careful as the radiator hoses are hot.

        • Keep your hands away from the radiator fan.

      2. After the engine has warmed up, run the engine according to the following pattern for at least 7 minutes: 3000 rpm for 5 seconds, and then idle speed for 45 seconds (repeat this pattern at least 8 times).

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

        CAUTION:

        When squeezing the radiator hoses:

        • Wear protective gloves.

        • Be careful as the radiator hoses are hot.

        • Keep your hands away from the radiator fan.

    8. A00OR7O

      After the engine has cooled down, check that the coolant level is between FULL and LOW.

      If the coolant level is low, add coolant until the coolant level leaks the reservoir tank FULL line.

  7. INSPECT FOR COOLANT LEAK


    1. Remove the radiator reservoir cap.

      CAUTION:

      To avoid the danger of being burned, do not remove the radiator reservoir cap while the engine and radiator are still hot. Thermal expansion will cause hot engine coolant and steam to blow out from the radiator.

    2. A003D2E

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

    3. Warm up the engine.

    4. Pump the radiator cap tester to 118 kPa (1.2 kgf/cm2, 17 psi), and then check that the pressure does not drop.

      If the pressure drops, check the hoses, radiator and water pump for leakage.

      If there are no signs of external coolant leaks, check the heater core, cylinder block and head.

    5. Reinstall the radiator reservoir cap.

  8. INSTALL RADIATOR SUPPORT OPENING COVER


    1. Install the radiator support opening cover with the 7 clips.

  9. INSTALL ENGINE UNDER COVER


    1. Install the engine under cover with the 11 clips.

  10. INSTALL FRONT LOWER BUMPER ABSORBER


    1. Insert the 2 hooks of the front lower bumper absorber into the installation holes on the body to install the front lower bumper absorber.

    2. Install the 8 bolts and 3 screws.

    3. Install the 4 screws and 2 bolts.
