  2. INSTALL V-RIBBED BELT TENSIONER ASSEMBLY


    1. When replacing the V-ribbed belt tensioner assembly with a new one.


      1. Install the V-ribbed belt tensioner assembly to the engine assembly with the 2 bolts.

        Note

        Make sure to install a new V-ribbed belt tensioner assembly with the pin and white cover installed to it.

        Torque:
        21 N*m  { 214 kgf*cm, 15 ft.*lbf }

      2. Remove the white cover.

      3. Rotate the V-ribbed belt tensioner assembly slightly clockwise and remove the pin that is used to keep the spring compressed.

        Note


        • Do not forcibly rotate the V-ribbed belt tensioner assembly to the V-ribbed belt installation position with the pin installed.

        • Do not apply or add any oil or grease to the V-ribbed belt tensioner assembly.

        Tech Tips

        When installing the V-ribbed belt, rotate the V-ribbed belt tensioner assembly clockwise again with the pin removed, and secure the V-ribbed belt tensioner assembly using a 5 mm hexagon wrench.

    2. When reusing the V-ribbed belt tensioner assembly.


      1. Check that the 3 mm hexagon wrench is installed to the V-ribbed belt tensioner assembly.

      2. Install the V-ribbed belt tensioner assembly to the engine assembly with the 2 bolts.

        Torque:
        21 N*m  { 214 kgf*cm, 15 ft.*lbf }

      3. Rotate the V-ribbed belt tensioner assembly slightly clockwise and remove the 3 mm hexagon wrench that is used to keep the spring compressed.

        Note

        Do not forcibly rotate the V-ribbed belt tensioner assembly to the V-ribbed belt installation position with the 3 mm hexagon wrench installed.

        Tech Tips

        When installing the V-ribbed belt, rotate the V-ribbed belt tensioner assembly clockwise again with the 3 mm hexagon wrench removed, and secure the V-ribbed belt tensioner assembly using a 5 mm hexagon wrench.

  4. ADD ENGINE COOLANT


    1. Tighten the radiator drain cock plug.

    2. A01IRFF

      Add TOYOTA Super Long Life Coolant (SLLC) through the radiator reservoir filler opening until the coolant reaches the B line.

      Standard Capacity
      Item Specified Condition
      5-bladed fan 5.6 liters (5.9 US qts, 4.9 Imp. qts)
      7-bladed fan 6.3 liters (6.7 US qts, 5.5 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.

    3. 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.

    4. Install the cap and warm up the engine sufficiently.

    5. 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 hose:

        • 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, repeat the following procedure for at least 7 minutes: run the engine at 3000 rpm for 5 seconds, and then at idle speed for 45 seconds (repeat this procedure 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 hose:

        • Wear protective gloves.

        • Be careful as the radiator hoses are hot.

        • Keep your hands away from the radiator fan.

    6. A01IRFF

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

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

  5. INSPECT FOR COOLANT LEAK

    CAUTION:

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


    1. A01IPAH

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

    2. Warm up the engine.

    3. Using the radiator cap tester, increase the pressure inside the radiator 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 or traces of external engine coolant leakage, check the heater core, cylinder block and head.
