  5. INSPECT V-RIBBED BELT


    1. A00507C

      Check the belt for wear, cracks or other signs of damage.

      If any of the following defects is found, replace the V-ribbed belt.


      • The belt is cracked.

      • The belt is worn out to the extent that the cords are exposed.

      • The belt has chunks missing from the ribs.

    2. A005369E02

      Check that the belt fits properly in the ribbed grooves.

      Tech Tips

      Check with your hand to confirm that the belt has not slipped out of the grooves on the bottom to the pulley. If it has slipped out, replace the V-ribbed belt. Install a new V-ribbed belt correctly.

    3. A004Z7CE01

      Check the V-ribbed belt deflection and tension.

      Standard Deflection
      Item Specified Condition
      New belt 7.0 to 8.2 mm (0.276 to 0.323 in.)
      Used belt 7.6 to 10.0 mm (0.299 to 0.394 in.)
      Standard Tension
      Item Specified Condition
      New belt 700 to 800 N (70 to 80 kgf, 157.4 to 179.8 lbf)
      Used belt 550 to 750 N (55 to 75 kgf, 123.6 to 168.6 lbf)

      Tech Tips


      • When inspecting the V-ribbed belt deflection, apply 98 N (10 kgf, 22.0 lbf) of tensile force to it.

      • Check the V-ribbed belt deflection at the specified point.

      • V-ribbed belt tension and deflection should be checked after 2 revolutions of engine cranking.

      • Measure the belt tension when the engine is cold.

      • When adjusting the belt, be sure to adjust it so that the tension is as close as possible to the median of the specified range.

      • When replacing the belt with a new one, be sure to perform the following after adjusting the belt: idle the engine for 5 minutes, and then adjust the belt to the specified value for a new belt after the engine has cooled.

      • When inspecting a belt which has been used for over 5 minutes, apply the used belt specifications.

      • When using a belt tension gauge, confirm its accuracy by using a master gauge first.

  6. CONNECT CABLE TO NEGATIVE BATTERY TERMINAL

    Note

    When disconnecting the cable, some systems need to be initialized after the cable is reconnected Click here.

  7. ADD ENGINE COOLANT


    1. Tighten the radiator drain cock plug.

    2. A00DQVX

      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
      for Manual transaxle 6.3 liters (6.7 US qts, 5.5 Imp. qts)
      for CVT 6.2 liters (6.6 US qts, 5.4 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. A00DQVX

      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.

  8. INSPECT FOR COOLANT LEAK

    CAUTION:

    To avoid being burned, do not remove the reserve tank 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. A005TAG

      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.

  9. INSTALL REAR ENGINE UNDER COVER RH


    1. A00OMDF

      Install the under cover RH with the 5 clips.

  10. INSTALL NO. 2 CYLINDER HEAD COVER


    1. A00OIJQ

      Attach the 4 clips to install the cover.

      Note


      • Be sure to attach the clips securely.

      • Do not apply excessive force or hit the cover to attach the clips. This may cause the cover to break.

  11. INSTALL RADIATOR SUPPORT OPENING COVER


    1. A00OKW2

      Install the radiator support opening cover with the 7 clips.
