  2. DRAIN ENGINE COOLANT

    CAUTION:

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


    1. Connect a hose with an inside diameter of 9 mm (0.354 in.) to the radiator drain cock as shown in the illustration.

    2. Loosen the radiator drain cock plug and drain the engine coolant.

      *1 Reservoir Cap *2 Air Release Valve
      *3 Radiator Drain Cock Plug - -

      Tech Tips

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

    3. Remove the reservoir cap.

    4. Tighten the radiator drain cock plug by hand.

    5. Disconnect the hose from the radiator drain cock.

  3. ADD ENGINE COOLANT

    CAUTION:

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


    1. A01V7A1C01
      *1 Air Release Valve
      *a Radiator Reservoir Sub-assembly Filler Neck Line
      *b Full Line

      Remove the air release valve.

    2. Add engine coolant to the full line of the radiator reservoir sub-assembly.

      Standard Capacity
      Item Specified Condition
      w/o Combustion Type Power Heater 7.0 liters (7.4 US qts, 6.2 Imp. qts)
      w/ Combustion Type Power Heater 7.3 liters (7.7 US qts, 6.4 Imp. qts)

      Note

      Never use water as a substitute for engine coolant.

      Tech Tips

      Toyota recommends the use of approved "Toyota Premium Long Life Coolant for 2WW engines" or equivalent.

    3. Press the No. 2 radiator hose and radiator hose sub-assembly several times by hand, and then check the level of the engine coolant.

      If the engine coolant level is low, add engine coolant.

    4. Install the air release valve.

    5. Add engine coolant to the filler neck line of the radiator reservoir sub-assembly.

    6. Install the reservoir cap.

    7. Start the engine, and warm it up until the fan operates.

      Note


      • Before starting the engine, turn the A/C switch off.

      • Adjust the heater control to the maximum hot setting.

      • Adjust the blower speed to the low setting.

    8. Maintain the engine speed at 2000 to 2500 rpm and warm up the engine until the fan operates.

      Note


      • Make sure that the radiator reservoir sub-assembly still has some engine coolant in it.

      • Pay attention to the needle of the water temperature meter. Make sure that the needle does not show an abnormally high temperature.

      • Operating the engine with low engine coolant may result in overheating or engine damage.

      • Immediately after starting the engine, if the radiator reservoir sub-assembly does not have any engine coolant, perform the following: 1) stop the engine, 2) wait until the engine coolant has cooled down, and 3) add engine coolant until the engine coolant is filled to the full line.

    9. Press the No. 2 radiator hose and radiator hose sub-assembly several times by hand to bleed air.

      CAUTION:


      • Wear protective gloves.

      • Be careful as the radiator hoses are hot.

      • Keep your hands away from the fan.

    10. Stop the engine and wait until the engine coolant cools down to ambient temperature.

    11. Check that the engine coolant level is between the full line and low line.


      • If the engine coolant level is below the low line, repeat all of the procedures above.

      • If the engine coolant level is above the full line, drain engine coolant so that the engine coolant level is between the full line and low line.
