NOTICE:

Be careful not to damage the radiator core.

Install the fluid coupling with fan to the fan pulley with the 4 nuts.
Tighten the nuts as much as possible by hand.

Attach the claws of the fan shroud to the radiator.

Install the fan shroud with the 2 bolts.

Torque:

5.0 N*m{51 kgf*cm, 44 in.*lbf}

Torque:

23 N*m{235 kgf*cm, 17 ft.*lbf}

Install the radiator reservoir with the 2 bolts.

Torque:

5.0 N*m{51 kgf*cm, 44 in.*lbf}

Connect the No. 1 and No. 2 water by-pass hoses to the radiator.

Install the oil reservoir with the 3 bolts.

Torque:

4.5 N*m{46 kgf*cm, 40 in.*lbf}

Connect the radiator hose inlet to the radiator.

Connect the radiator hose outlet to the radiator.

Tighten the radiator drain cock plug by hand.

Tighten the cylinder block drain cock plug.

Torque:

8.0 N*m{82 kgf*cm, 71 in.*lbf}

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

Standard capacity:

9.8 liters (10.4 US qts, 8.6 Imp. qts)

NOTICE:

Never use water as a substitute for engine coolant.

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.
   

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, 17 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.
   

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:

   1. Wear protective gloves.
      
   2. Be careful as the radiator hoses are hot.
      
   3. 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.

Fill the radiator with coolant and attach a radiator cap tester.

Warm up the engine.

Using the radiator cap tester, increase the pressure inside the radiator to 118 kPa (1.2 kgf/cm², 17 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 heater core, cylinder block and head.

Install the radiator side deflector LH with the 3 clips and attach the claw.

Install the radiator side deflector RH with the 3 clips and attach the claw.

Attach the 6 claws to install the radiator grille.

Install the 2 screws and 2 clips.
