Add engine coolant through the radiator reservoir filler opening until the engine coolant reaches the "B" line.

Standard Capacity:

Item		Specified Condition
for Manual Transmission	except Cold Area Specification Vehicle	10.1 liters (10.7 US qts, 8.9 Imp. qts)
	for Cold Area Specification Vehicle	11.9 liters (12.6 US qts, 10.5 Imp. qts)
for Automatic Transmission	except Cold Area Specification Vehicle	10.0 liters (10.6 US qts, 8.8 Imp. qts)
	for Cold Area Specification Vehicle	11.8 liters (12.5 US qts, 10.4 Imp. qts)

NOTICE:

Do not substitute plain water for engine coolant.

HINT:

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 is a combination of low phosphates and organic acids).

Press the No. 1 radiator hose and No. 2 radiator hose several times by hand, and then check the level of the engine coolant.
If the coolant level drops below the B line, add engine coolant to the B line.

Install the radiator reservoir cap sub-assembly.

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.
   

   NOTICE:

   1. Immediately after starting the engine, if the radiator reservoir sub-assembly does not have any engine coolant, perform the following: 1) stop the engine, 2) wait until the engine coolant has cooled down, and 3) add engine coolant.
      
   2. Do not start the engine when there is no coolant in the radiator reservoir sub-assembly.
      
   3. Make sure that the needle does not show an abnormally high temperature.
      
   4. If there is not enough coolant, the engine may overheat.
      

   HINT:

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

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

3. Press the No. 1 radiator hose and No. 2 radiator hose several times by hand to bleed air.
   

Stop the engine, and wait until the engine coolant cools down to ambient temperature.

Check the coolant level in the radiator reservoir sub-assembly.
If the coolant level is low, add engine coolant to the radiator reservoir sub-assembly full line.

Remove the radiator reservoir cap sub-assembly.

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

Warm up the engine.

Using the radiator cap tester, increase the pressure inside the radiator assembly 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 assembly and engine water pump assembly for leaks.
If there are no signs or traces of external engine coolant leakage, check the heater core, cylinder block assembly and cylinder head sub-assembly.

Remove the radiator cap tester and install the radiator reservoir cap sub-assembly.

Install the upper radiator support seal with the 13 clips.
