9. Connect the No. 1 and No. 2 water by-pass hoses to the tank upper and lower.
10. Install the oil reservoir with the 3 bolts.
  
  Torque:
  
  4.5 N*m { 46 kgf*cm, 40 in.*lbf }
CONNECT RADIATOR HOSE INLET

ADD ENGINE COOLANT

Tighten the cylinder block drain cock plug.

Torque:

8.0 N*m { 82 kgf*cm, 71 in.*lbf }
Tighten the radiator drain cock plug by hand.

Fill the radiator with TOYOTA Super Long Life Coolant (SLLC) to the reservoir tank's B line.

Standard capacity

Item	Specified Condition
A/T	11.1 liters (11.7 US qts, 9.8 Imp. qts)
M/T	9.8 liters (10.4 US qts, 8.6 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 consists of a combination of low phosphates and organic acids).

Note

Never use water as a substitute for engine coolant.

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 B line, add TOYOTA SLLC to the B line.
Install the radiator reservoir cap.
Using a wrench, install the vent plug.

Torque:

2.0 N*m { 20 kgf*cm, 18 in.*lbf }
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.
  
  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.
2. Maintain the engine speed at 2500 to 3000 rpm.
3. Press the inlet and outlet radiator hoses several times by hand to bleed air.
  CAUTION:
  
  When pressing the radiator hoses:
  - Wear protective gloves.
  - Be careful as the radiator hoses are hot.
  - Keep your hands away from the radiator fan.
4. Stop the engine and wait until the coolant cools down to ambient temperature.
  
  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.
After the coolant cools down, check that the coolant level is at the F line.

If the coolant level is below the F line, add TOYOTA SLLC to the F line.

INSPECT FOR COOLANT LEAK
Note

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.
1. Fill the radiator with coolant and attach a radiator cap tester to the radiator reservoir.
2. Warm up the engine.
3. Using a radiator cap tester, increase the pressure inside the radiator to 118 kPa (1.2 kgf/cm², 17.1 psi), and check that the pressure does not drop.
  
  If the pressure drops, check the hoses, radiator and water pump for leaks.
  
  If no external leaks are found, check the cylinder block and head.
