ENGINE COOLANT TEMPERATURE SENSOR INSTALLATION

INSTALL ENGINE COOLANT TEMPERATURE SENSOR
1. Install a new gasket to the engine coolant temperature sensor.
2. Using a union nut wrench 19 mm, install the engine coolant temperature sensor.
  
  Torque:
  
  20 N*m { 200 kgf*cm, 14 ft.*lbf }
  
  Note
  
  Use the torque value compensation formula to calculate the torque value for use when a torque wrench is combined with a tool such as a union nut wrench Click here.
3. Connect the engine coolant temperature sensor connector.
INSTALL INVERTER RESERVE TANK ASSEMBLY
1. Temporarily instal the inverter reserve tank assembly with bolt A.
2. Tighten the 2 bolts to the inverter reserve tank assembly in the following order: bolt B and bolt A.
  
  Torque:
  
  10 N*m { 102 kgf*cm, 7 ft.*lbf }

*1	B Line

Add coolant to B line of the reservoir tank.

Standard Capacity

Item	Capacity
Engine coolant	7.2 liters (7.6 US qts, 6.3 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 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 (maintenance 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 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.

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 (maintenance mode) Click here.
4. Warm up the engine.
5. Using the reservoir 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 water pump 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.
INSPECT FOR FUEL LEAK
1. Check fuel pump operation.
  1. Connect the GTS to the DLC3.
  2. Turn the power switch on (IG).
    
    Note
    
    Do not start the engine.
  3. Turn the GTS on.
  4. Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the Fuel Pump / Speed.
  5. Check for pressure in the fuel inlet tube from the fuel line. Check that sounds of fuel flowing from the fuel tank can be heard. If no sounds can be heard, check the integration relay, fuel pump, ECM and wiring connectors.
2. Inspect for fuel leaks.
  1. Check that there is no fuel leakage after performing maintenance anywhere on the fuel system. If there is a fuel leak, repair or replace parts as necessary.
3. Turn the power switch off.
4. Disconnect the GTS from the DLC3.
