ADD ENGINE COOLANT (for Engine)

Tighten the radiator drain cock plug.
Connect the hose to the air release valve. (w/ Air Release Valve)
Loosen the air release valve. (w/ Air Release Valve)
Add TOYOTA Super Long Life Coolant (SLLC) to the reservoir tank filler opening until coolant overflows from the air release valve. Then tighten the air release valve. (w/ Air Release Valve)
Disconnect the hose from the air release valve. (w/ Air Release Valve)

Add TOYOTA Super Long Life Coolant (SLLC) to the B line on the reservoir tank.

Standard Capacity

Item

Capacity

Engine coolant

w/ Exhaust Heat Recirculation System:

7.2 liters (7.6 US qts, 6.3 lmp. qts)

w/o Exhaust Heat Recirculation System:

6.5 liters (6.8 US qts, 5.7 lmp. 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 is a combination of low phosphates and organic acids).

Note

Never use water as a substitute for engine coolant.

Squeeze the inlet and outlet radiator hoses several times by hand, and then check the level of the coolant.

If the coolant level is low, add coolant.
Put the engine in inspection mode Click here.
Install the reservoir tank cap.
Bleed air from the cooling system.
Note
- Before starting the engine, turn the A/C switch off.
- Adjust the heater control to the maximum hot setting.
- Adjust the blower speed to the low setting.
1. Warm up the engine until the thermostat opens. While the thermostat is open, allow the coolant to circulate for several minutes.
  
  Tech Tips
  
  The thermostat opening timing can be confirmed by squeezing the inlet radiator hose by hand, and sensing vibrations when the engine coolant starts to flow inside the hose.
  CAUTION:
  When squeezing the radiator hose:
  - Wear protective gloves.
  - Be careful as the radiator hoses are hot.
  - Keep your hands away from the radiator fan.
2. Squeeze the inlet and outlet radiator hoses several times by hand to bleed air from the system.
  CAUTION:
  When squeezing the radiator hose:
  - Wear protective gloves.
  - Be careful as the radiator hoses are hot.
  - Keep your hands away from the radiator fan.

*1 Full Line

*2 Low Line

After the engine has cooled down, check that the coolant level is between full and low lines.

If the coolant level is low, add coolant to the full line on the reservoir tank.

INSPECT FOR COOLANT LEAK (for Engine)
CAUTION:

Do not remove the reservoir tank cap while the engine and radiator are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.

Note

Before performing each inspection, turn the A/C switch off.
1. Remove the reservoir tank cap.
2. Fill the radiator and reservoir with coolant, and then attach a radiator cap tester.
3. Put the engine in inspection mode Click here.
4. Warm up the engine.
5. Using a radiator cap tester, increase the pressure inside the radiator to 108 kPa (1.1 kgf/cm², 16 psi), and check that the pressure does not drop. If the pressure drops, check the hoses, radiator, front exhaust pipe assembly and the heater hose around and engine water pump assembly for leaks. If no external leaks are found, check the heater core, cylinder block and cylinder head.
6. Remove the radiator cap tester.
7. Install the reservoir tank cap.
INSTALL NO. 2 CYLINDER HEAD COVER
1. Engage the 3 clips to install the cover.
  Note
  - Be sure to engage the clips securely.
  - Do not apply excessive force or hit the cover to engage the clips. This may cause the cover to break.
INSTALL NO. 1 ENGINE UNDER COVER

PERFORM INITIALIZATION

Note

Be sure to perform this procedure after reassembling the throttle body assembly, removing and reinstalling any throttle body component or replacing the ECM.

Disconnect the cable from the negative (-) battery terminal. Wait at least 60 seconds and reconnect the cable.
Connect the intelligent tester to the DLC3 and clear the DTCs Click here.
Set the vehicle to inspection mode Click here.

Start the engine without operating the accelerator pedal and check that the MIL is not illuminated and that the idle speed is within the specified range when the air conditioning is switched off after the engine is warmed up.

Standard

Condition	Engine Idle Speed
A/C switched off	950 to 1050 rpm

Note

If the accelerator pedal is operated, perform the above steps again.
Be sure to perform this step with all accessories off.
Make sure that park (P) is selected.

Perform a road test and confirm that there are no abnormalities.
