Engage the 2 claws and install the fan shroud.

Install radiator hose No. 3 with the 2 clips.

Connect the radiator reservoir tank hose to the water filler.

Install the air cleaner case with air cleaner inlet No. 1 with the 2 bolts.

Torque:

7.8 N*m{80 kgf*cm, 69 in.*lbf}

Connect the wire harness to the air cleaner case.

Install the air cleaner element.

Install and lock the air cleaner cap and the air cleaner hose and then tighten the air cleaner hose clamp.

Torque:

4.0 N*m{41 kgf*cm, 35 in.*lbf}

Connect the ventilation hose to the air cleaner hose.

Connect the vacuum switching valve connector and the wire harness clamp.

Connect the fuel vapor feed hose to the vacuum switching valve assembly and air cleaner hose.

Connect the intake air flow meter connector and the wire harness clamp.

Tighten all the plugs.

Pour engine coolant into the radiator assembly until it overflows.

Capacity:

M/T 4.8 liters (5.1 USqts, 4.5 lmp. qts)

A/T 4.7 liters (5.0 USqts, 4.4 lmp. qts)

NOTICE:

Do not substitute water for engine coolant.

HINT:

1. Use of improper engine coolant may damage the engine coolant system.
   
2. Use only Toyota Super Long Life Coolant or similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite, and non-borate engine 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).
   

Check the engine coolant level inside the radiator assembly by squeezing the inlet and outlet radiator hoses several times by hand. If the engine coolant level goes down, add engine coolant.

Install the radiator cap sub-assembly securely.

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

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.
   

   HINT:

   The thermostat open timing can be confirmed by pressing the No. 2 radiator hose by hand, and checking when when the coolant starts to flow inside the hose.

2. Maintain the engine speed at 2,000 to 2,500 rpm and warm up the engine until the cooling fan operates.
   

3. Press the No. 2 radiator hose and No. 3 radiator hose several times by hand to bleed air.
   

   NOTICE:

   When pressing the radiator houses

   1. Wear protective glove.
      
   2. Be careful as the radiator hoses are hot.
      
   3. Keep your hands away form the radiator fan.
      

Stop the engine and wait until the coolant cools down.

If the engine coolant level is below the full level, perform steps (b) through (g) again and repeat the operation until the engine coolant level stays at the full level.

Recheck the engine coolant level inside the radiator reservoir tank assembly. If it is below the full level, add engine coolant.

Fill the radiator assembly with engine coolant, and attach a radiator cap tester.

Pump the tester to 118 kPa (1.2 kgf/cm², 17.1 psi), and then check that the pressure does not drop.
If the pressure drops, check the hoses, radiator assembly and water pump assembly for leaks. If there are no signs or traces of external engine coolant leaks, check the heater core, cylinder block and head.
