COOLANT REPLACEMENT


  1. REMOVE V-BANK COVER SUB-ASSEMBLY


    1. A017EFM

      Hold the front of the V-bank cover sub-assembly and raise it to disengage the 2 clips on the front of the V-bank cover sub-assembly. Continue rising the V-bank cover sub-assembly to disengage the clip on the rear of the V-bank cover sub-assembly and remove the V-bank cover sub-assembly.

      Note

      Attempting to disengage both front and rear clips at the same time may cause the V-bank cover sub-assembly to break.

  2. REMOVE ENGINE UNDER COVER ASSEMBLY


    1. A017FPR

      Remove the 2 bolts and engine under cover assembly RR.

    2. A017FXN

  4. DRAIN ENGINE COOLANT


    1. Loosen the radiator drain cock plug.

      A017CW8E01

      Tech Tips

      Collect the coolant in a container and dispose of it according to the regulations in your area.

    2. Remove the radiator cap sub-assembly from the radiator assembly.

      Note

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

    3. Loosen the 2 cylinder block drain cock plugs.

  5. ADD ENGINE COOLANT


    1. Tighten the radiator drain cock plug by hand.

    2. Tighten the 2 cylinder block drain cock plugs.

      Torque:
      13 N*m  { 130 kgf*cm, 9 ft.*lbf, for cylinder block drain cock plugs }

    3. Loosen the air drain cock plug from the water inlet housing.

    4. A017G9AE01

      Loosen the air drain plug at the top of the radiator 3 or 4 turns.

    5. Add TOYOTA Super Long Life Coolant (SLLC) to the radiator inlet opening until coolant overflows from the engine air drain cock hole. Then tighten the air drain cock plug to the water inlet housing.

      Torque:
      13 N*m  { 130 kgf*cm, 9 ft.*lbf, for air drain cock plug }

    6. Continue to add TOYOTA Super Long Life Coolant (SLLC) to the radiator inlet opening until coolant overflows from the radiator air drain hole. Then close the air drain plug at the top of the radiator.

      Torque:
      1.5 N*m  { 15 kgf*cm, 13 in.*lbf, for air drain plug }

      Tech Tips

      If the coolant level at the radiator inlet opening drops after squeezing the No. 1 and No. 2 radiator hoses, add coolant.

    7. Slowly fill the radiator with TOYOTA Super Long Life Coolant (SLLC).

      Standard capacity
      w/o Engine oil cooler
      Condition Specified Condition
      w/ Rear Heater 11.0 liters (11.6 US qts, 9.7 Imp. qts)
      w/o Rear Heater 8.8 liters (9.3 US qts, 7.7 Imp. qts)
      w/ Engine oil cooler
      Condition Specified Condition
      w/ Rear Heater 11.7 liters (12.4 US qts, 10.3 Imp. qts)
      w/o Rear Heater 9.5 liters (10.1 US qts, 8.4 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 consists of 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.

    8. Slowly pour coolant into the radiator reservoir tank until it reaches the FULL line.

    9. Squeeze the No. 1 and No. 2 radiator hoses several times by hand, and then check the level of the coolant.

      If the coolant level is low, add coolant.

    10. Bleed air from the cooling system.


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

        Tech Tips

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

      2. Maintain the engine speed at 2500 to 3000 rpm.

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

        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.

        Note


        • Make sure that the radiator reservoir 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.

        • If the radiator reservoir does not have enough coolant, perform the following: 1) stop the engine, 2) wait until the coolant has cooled down, and 3) add coolant until the reservoir is filled to the FULL line.

    11. Stop the engine and wait until the engine coolant cools down.

    12. Add engine coolant to the FULL line on the radiator reservoir.

  6. INSPECT FOR COOLANT LEAK

    CAUTION:

    Do not remove the radiator 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. A017G83

      Fill the radiator with coolant and 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 check that the pressure does not drop.

      If the pressure drops, check the hoses, radiator and water pump for leaks. If no external leaks are found, check the heater core, cylinder block and cylinder head.

  7. INSTALL NO. 1 ENGINE UNDER COVER


    1. A017B8T

      Install the No. 1 engine under cover with the 6 bolts and 2 clips.

  8. INSTALL ENGINE UNDER COVER ASSEMBLY


    1. A017FXN

      Install the engine under cover assembly with the 2 bolts, 2 screws and 5 clips.

    2. A017FPR

      Install the engine under cover assembly RR with the 2 bolts.

  9. INSTALL V-BANK COVER SUB-ASSEMBLY


    1. A017EFM
