      Attach the clamp to the water by-pass hose.

      Note


      • Make sure that the marking on the water by-pass hose is aligned with the center of the clamp.

      • Make sure that the breather hose is positioned on the left side of the vehicle.

      • Make sure that the breather plug is inclined as shown in the illustration.

      • Make sure that the hose is not kinked.

  5. CONNECT WATER BY-PASS HOSE (w/ Air Cooled Transmission Oil Cooler)


    1. Connect the 2 water by-pass hoses to the oil cooler and engage the 2 clamps.

      Note

      Fully insert the 2 water by-pass hoses until the 2nd rib on each oil cooler pipe.

  6. CONNECT NO. 1 RADIATOR HOSE


    1. Connect the No. 1 radiator hose.

    2. Connect the wire clamp.

  7. ADD ENGINE COOLANT


    1. Tighten the radiator drain cock plug by hand.

    2. Tighten the cylinder block drain cock plug.

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

    3. Remove the reserve tank cap. (*1)

    4. Add TOYOTA Super Long Life Coolant (SLLC).

      Standard capacity
      8.6 liters (9.1 US qts, 7.6 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).

      • Squeeze the No. 1 and No. 2 radiator hoses several times. If the coolant level at the water inlet opening drops, add TOYOTA SLLC.

      Continue adding TOYOTA SLLC until it reaches the B line. (*2)

    6. Install the reserve tank cap. (*3)

    7. Run the engine at about 2000 rpm to warm it up until the thermostat opens. While the thermostat is open, circulate the coolant for several minutes. (*4)

      CAUTION:


      • When pushing the radiator hoses, wear protective gloves.

      • Be careful as the radiator hoses, engine and radiator are hot.

      • Keep your hands away from the radiator fans.

      Note


      • If the radiator reserve tank runs out of coolant just after the engine is started, stop the engine immediately, wait until the coolant has cooled down, and then add coolant.

      • Make sure that the reserve tank still has some coolant in it.

      • If the coolant temperature gauge indicates an excessive temperature, turn off the engine and let it cool.

      • If there is not enough coolant, the engine may overheat or be seriously damaged.

    8. Stop the engine and wait until the coolant cools down. (*5)

      *1 Full Line
      *2 Low Line

      Check that the coolant level is between the full and low lines. (*6)

      Tech Tips


      • If the coolant level is below the low line, repeat steps from (*1) to (*6).

      • If the coolant level is above the full line, drain coolant so that the coolant level is between the full and low lines.

  8. ADD CONTINUOUSLY VARIABLE TRANSAXLE FLUID

  9. INSPECT FOR COOLANT LEAK


    1. Remove the reserve tank cap.

      CAUTION:

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

      *1 Radiator Cap Tester

      Fill the radiator and radiator reserve tank 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 leaks.

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

    5. Reinstall the reserve tank cap.

  10. INSPECT FOR OIL LEAK

  11. INSTALL RADIATOR COVER SUB-ASSEMBLY


    1. Install the radiator cover sub-assembly with the 4 clips.

  12. INSTALL NO. 1 ENGINE UNDER COVER

  13. INSTALL REAR ENGINE UNDER COVER LH

  14. INSTALL FRONT WHEEL LH
