COOLANT REPLACEMENT

PROCEDURE


  1. 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 reserve tank cap.

      CAUTION:

      Do not remove the reserve tank cap while the engine and radiator are still hot.

      Pressurized, hot engine coolant and steam may be released and cause serious burns.

  2. ADD ENGINE COOLANT


    1. Tighten the radiator drain cock plug.

      Add TOYOTA Super Long Life Coolant (SLLC) through the radiator reservoir filler opening until the coolant reaches the B line.

      Standard Capacity
      Item Specified Condition
      for Manual Transaxle 6.3 liters (6.7 US qts, 5.5 Imp. qts)
      for CVT 6.2 liters (6.6 US qts, 5.4 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 is a combination of low phosphates and organic acids).

      Note

      Never use water as a substitute for engine coolant.

    3. 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.

    4. Install the cap and warm up the engine sufficiently.

    5. 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 hose:
        • 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, repeat the following procedure for at least 7 minutes: run the engine at 3000 rpm for 5 seconds, and then at idle speed for 45 seconds (repeat this procedure 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 hose:
        • Wear protective gloves.

        • Be careful as the radiator hoses are hot.

        • Keep your hands away from the radiator fan.

      After the engine has cooled down, check that the coolant level is between FULL and LOW lines.

      If the coolant level is low, add coolant to the FULL line on the reservoir tank.
