COOLANT REPLACEMENT


  1. REMOVE FRONT LOWER BUMPER ABSORBER


    1. A006VZN

      Remove the 4 screws and 2 bolts.

    2. A006W5E

      Remove the 8 bolts and 3 screws.

    3. Detach the 2 hooks of the front lower bumper absorber from the installation holes on the body and remove the front lower bumper absorber.

  2. REMOVE ENGINE UNDER COVER


    1. A006TQR

      Remove the 11 clips the engine under cover.

  3. DRAIN ENGINE COOLANT


    1. Loosen the radiator drain cock plug.

      Tech Tips

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

    2. Remove the radiator reservoir cap.

      CAUTION:

      Do not remove the radiator reservoir cap and air release plug while the engine and radiator are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.

    3. Loosen the cylinder block drain cock plug. Then drain the coolant from the engine.

      Tech Tips

      The plug is on the backside of the generator on the EGR cooler side.

  4. 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.

      *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 reaches the reservoir tank FULL line.

  5. 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.

  6. INSTALL ENGINE UNDER COVER


    1. A00EB0Y

      Install the engine under cover with the 11 clips.

  7. INSTALL FRONT LOWER BUMPER ABSORBER


    1. A00E73K

      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 8 bolts and 3 screws.

    3. A00E7US

      Install the 4 screws and 2 bolts.
