10. ADD ENGINE COOLANT

1. Tighten all the plugs and fill the radiator with TOYOTA Super Long Life Coolant (SLLC).

   Torque:
     24.5 N*m{ 250 kgf*cm , 18 ft.*lbf } for cylinder block drain cock plug

   Standard capacity:
     7.0 liters (7.4 US qts, 6.2 lmp. qts)

1. Fill the radiator with TOYOTA Super Long Life Coolant (SLLC) to the F line.

   HINT:
   1. 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 consists of a combination of low phosphates and organic acids).
   2. Please contact your TOYOTA dealer for further details.

      NOTICE:
        Never use water as a substitute for engine coolant.

1. Press the inlet and outlet radiator hoses several times by hand, and then check the level of the coolant.
   If the coolant level drops below the F line, add TOYOTA SLLC to the F line.

1. Install the radiator cap.

1. Bleed air from the cooling system.

   1. Warm up the engine until the thermostat opens. While the thermostat is open, circulate the coolant for several minutes.

   2. Maintain the engine speed at 2,000 to 2,500 rpm.

   3. Press the inlet and outlet radiator hoses several times by hand to bleed air.

      CAUTION:
      When pressing the radiator hoses:
      1. Wear protective gloves.
      2. Be careful as the radiator hoses are hot.
      3. Keep your hands away from the radiator fan.

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

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

1. Check the coolant level in the radiator reservoir.
   If the coolant level is low, add SLLC to the reservoir F line.

11. CHECK FOR ENGINE COOLANT LEAKS

1. Check for the engine coolant leaks (Click here).

12. INSTALL NO. 1 ENGINE UNDER COVER

1. Install the cover with the 4 bolts.
