3. Remove the reserve tank cap. (*1)

4. Loosen the air drain cock plug on the water inlet housing.

5. Add TOYOTA Super Long Life Coolant (SLLC).

   Standard capacity
   10.6 liters (11.2 US qts, 9.3 Imp. qts)

   Note:

   Never use water as a substitute for engine coolant.

   Tip:
   

   • 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).

   • Squeeze the No. 1 and No. 2 radiator hoses several times. If the coolant level at the water inlet opening drops, add TOYOTA SLLC.

6. Add TOYOTA SLLC to the reserve tank until coolant overflows from the air drain cock plug hole. Then tighten the air drain cock plug on the water inlet housing.

7. 

   Continue adding TOYOTA SLLC until it reaches the B line. (*2)

8. Install the reserve tank cap. (*3)

9. Run the engine at about 2000 rpm to warm it up until the thermostat opens. While the thermostat is open, circulate the coolant for several minutes. (*4)

   CAUTION:
   
   

   • When push the radiator hoses, wear protective gloves.

   • Be careful as the radiator hoses, engine and radiator are hot.

   • Keep your hands away from the radiator fans.

   Note:
   

   • If the radiator reserve tank runs out of coolant just after the engine is started, stop the engine immediately, wait until the coolant has cooled down, and then add coolant.

   • Make sure that the reserve tank still has some coolant in it.

   • If the coolant temperature gauge indicates an excessive temperature, turn off the engine and let it cool.

   • If there is not enough coolant, the engine may overheat or be seriously damaged.

   Tip:
   

   • 

     If coolant comes out from the bypass hose port connected to the reserve tank, the thermostat has been opened.

   • After the thermostat has opened, idle the engine until the coolant in the reserve tank goes from being cloudy to a clear red.

10. Stop the engine and wait until the coolant cools down. (*5)

11. 

    Check that the coolant level is between the FULL and LOW lines. (*6)

    Tip:
    

    • If the coolant level is below the LOW line, repeat steps from (*1) to (*6).

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

INSPECT FOR ENGINE COOLANT LEAK

1. Remove the radiator reservoir cap.

   CAUTION:

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

2. 

   Fill the radiator and reservoir with coolant, and then attach a radiator cap tester.

3. Warm up the engine.

4. Pump the radiator cap tester to 118 kPa (1.2 kgf/cm², 17 psi), and then check that the pressure does not drop.

   If the pressure drops, check the hoses, radiator and water pump for leaks.

   If there are no signs of external coolant leaks, check the heater core, cylinder block and head.

5. Reinstall the radiator reservoir cap.
