Engine Coolant Temperature Sensor Installation

Install a new gasket to the sensor.

Using a 19 mm deep socket wrench, install the sensor.

Torque:

20 N*m{204 kgf*cm, 15 ft.*lbf}

Connect the sensor connector.

Remove the engine air bleed cap.

Connect a clear hose to the engine air bleed pipe.

Using a wrench, remove the vent plug.

Fill the radiator with TOYOTA SLLC to the radiator reservoir filler neck.

HINT:

Pour TOYOTA SLLC until it spills out of the engine air bleed pipe.

Standard Capacity (for Automatic Transmission):

Item	Specified Condition
Front heater only	14.8 liters (15.6 US qts, 13.0 Imp. qts)
Front heater and rear heater	17.6 liters (18.6 US qts, 15.5 Imp. qts)
Front heater with viscous heater	15.2 liters (16.1 US qts, 13.4 Imp. qts)
Front heater and rear heater with viscous heater	18.0 liters (19.0 US qts, 15.4 Imp. qts)

Standard capacity (for Manual Transmission):

15.4 liters (16.3 US qts, 13.5 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 consists of a combination of low phosphates and organic acids).

Install the vent plug.

Torque:

2.0 N*m{20 kgf*cm, 18 in.*lbf}

NOTICE:

Do not tighten the plug to 5.0 N*m (51 kgf*cm, 44 in.*lbf) or more, as the plug will be damaged.

Disconnect the clear hose from the engine air bleed pipe.

Install the engine air bleed cap when coolant comes out.

Install the radiator reservoir cap.

Start the engine.

NOTICE:

Immediately after starting the engine, if the radiator reservoir does not have any coolant, perform the following: 1) stop the engine, 2) wait until the coolant has cooled down, and 3) add coolant until the coolant is filled to the FULL line.

Maintain an engine speed of 3000 rpm for approximately 10 minutes so that the thermostat opens and air bleeding is performed.

CAUTION:

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

NOTICE:

1. Pay attention to the needle of the water temperature meter. Make sure that the needle does not show an abnormally high temperature.
   
2. If there is not enough coolant, the engine may burn out or overheat.
   

HINT:

The thermostat opening 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.

Stop the engine, and wait until the engine 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.

Check that the coolant level is between the FULL and LOW lines.
If the coolant level is above the FULL line, drain coolant so that the coolant level is between the FULL and LOW lines.

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

Warm up the engine.

Using the radiator cap tester, increase the pressure inside the radiator to 123 kPa (1.3 kgf/cm², 17.8 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 cylinder block and cylinder head.

Install the No. 1 engine under cover with the 10 bolts.

Torque:

29 N*m{296 kgf*cm, 21 ft.*lbf}

Install the front fender splash shield RH with the clip, and then install the 3 bolts and 2 screws.

Install the front fender splash shield LH with the clip, and then install the 3 bolts and screw.

Install the engine cover with the 2 nuts.

Torque:

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