COOLANT REPLACEMENT


  1. DRAIN ENGINE COOLANT

    A01BCB6E01

    CAUTION:

    To avoid the danger of being burned, do not remove the radiator reserve tank cap while the engine and radiator are still hot. Thermal expansion will cause hot engine coolant and steam to blow out from the radiator.


    1. Loosen the radiator drain plug (on the radiator).

    2. Remove the radiator cap.

    3. Loosen the engine drain plug (on the engine oil cooler cover), and drain the coolant.

    4. Tighten the engine drain plug (on the radiator).

    5. Tighten the engine drain plug (on the engine oil cooler cover).

      Torque:
      8.0 N*m  { 82 kgf*cm, 71 in.*lbf }

  2. ADD ENGINE COOLANT


    1. Firmly tighten the drain plugs.

    2. Fill the radiator reserve tank assembly with coolant to the top of the inlet.

      Coolant capacity
      Condition Capacity
      w/ rear heater 18.2 liters (19.2 US qts, 16.0 lmp. qts)
      w/o rear heater 16.2 liters (17.0 US qts, 14.0 lmp. qts)

      Note

      Do not substitute plain water for engine coolant.

      Tech Tips


      • Use of improper coolants may damage the engine cooling system.

      • Use only Toyota Super Long Life Coolant or similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite, and 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).

    3. Loosen the bleeder plug of the outlet housing.

    4. When air is bled and the coolant drains out, firmly install the bleeder plug.

    5. A01BGFB

      Add coolant up to the B line mark in the radiator reserve tank assembly and install the radiator cap.

    6. Warm up the engine until the thermostat opens.


      1. While the thermostat is open, circulate the coolant for several minutes.

        Tech Tips

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

    7. A01BBOM

      After the engine cools down, check that the coolant level is between the LOW and FULL level marks.

  3. INSPECT FOR COOLANT LEAK

    CAUTION:

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


    1. Fill the radiator with coolant and attach a radiator cap tester to the radiator.

    2. Warm up the engine.

    3. Using a radiator cap tester, increase the pressure inside the radiator to 137 kPa (1.4 kgf/cm2, 19.9 psi), and check that the pressure does not drop.

      Tech Tips

      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.
