   Loosen the radiator drain plug (on the radiator).

2. Remove the radiator cap.

3. Loosen the engine drain plug (on the oil cooler cover), and drain the coolant.

4. Drain the coolant from the reservoir tank.

5. Tighten the engine drain plug.

ADD ENGINE COOLANT

1. Pour coolant into the radiator until it overflows.

   Capacity
   Specification Capacity w/o Heater 9.8 liters (10.3 US qts, 8.6 Imp. qts) w/ Front Heater 10.7 liters (11.3 US qts, 9.4 Imp. qts) w/ Front and Rear Heater 11.5 liters (12.2 US qts, 10.1 Imp. qts)

   Note

   Do not substitute plain water for engine coolant.

   Tech Tips

   
   

   • Use of improper coolants may damage the engine cooling system.

   • Use only Toyota Super Long Life Coolant or similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite, and 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. Check the coolant level inside the radiator by squeezing the inlet and outlet radiator hoses several times by hand.

   If the coolant level goes down, add coolant.

3. Install the radiator cap securely.

4. Slowly pour coolant into the radiator reservoir until it reaches the FULL line.

5. Warm up the engine until the thermostat opens.

   
   

   1. While the thermostat is open, circulate the coolant for several minutes.

      Tech Tips

      The thermostat open timing can be confirmed by pressing the inlet radiator hose by hand, and checking when the engine coolant starts to flow inside the hose.

6. Maintain the engine speed at 2000 to 2500 rpm.

7. Squeeze the inlet and outlet radiator hoses several times by hand while warming up the engine to bleed the air.

   CAUTION:

   
   

   When squeezing the radiator hoses:

   • Wear protective gloves.

   • Be careful as the radiator hoses are hot.

   • Keep your hands away from the fan.

8. Stop the engine and wait until the coolant cools down.

9. Remove the radiator cap and check the coolant level inside the radiator.

10. If the coolant level is below the full level, repeat the operation until the coolant level remains at the full level.

11. Check the coolant level inside the radiator reservoir tank again.

    If it is below the full level, add coolant.
