  2. DRAIN ENGINE COOLANT

    CAUTION:

    Do not remove the reservoir cap and 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. Loosen the radiator drain cock plug and drain the engine coolant.

      Tech Tips

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

    2. Remove the reservoir cap.

  3. ADD ENGINE COOLANT

    CAUTION:

    Do not remove the reservoir cap and 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. Tighten the radiator drain cock plug by hand.

      Remove the air release valve.

    3. Add engine coolant to the pour limit line of the radiator reservoir 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 1WW/2WW engines" or equivalent.

    4. 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 coolant level is low, add engine coolant.

    5. Install the air release valve.

    6. Add engine coolant to the filler neck of the radiator reservoir assembly.

    7. Install the reservoir cap.

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

      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.

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

      Note


      • Make sure that the radiator reservoir 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.

      • If there is not enough engine coolant, the engine may burn out or overheat.

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

      • Until the coolant level has stabilized, run the engine intermittently as follows: 1) run the engine for 5 seconds at 3000 rpm with no load. 2) idle for 45 seconds with no load. 3) repeat the steps above 8 times or more until the level stops changing.

    10. 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 cooling fan.

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

    12. Check that the coolant level is between the FULL and LOW line.

      If the coolant level is below the LOW line, repeat all of the procedures above.

      If the coolant level is above the FULL line, drain coolant so that the coolant level is between the FULL and LOW line.
