Throttle Body Installation

Install a new gasket into the intake manifold.

Install the throttle body with the 2 bolts and 2 nuts.

Torque:

10 N*m{102 kgf*cm, 7 ft.*lbf}

Connect the throttle body connector and 2 water hoses.

Insert the hinge part of the air cleaner cap and hose into the air cleaner case, and then fasten the 2 hook clamps.

Connect the No. 1 air cleaner hose to the throttle body and push apart the tabs of the No. 1 air cleaner hose clamp.

HINT:

The direction of the hose clamp is indicated in the illustration.

Connect the No. 2 ventilation hose to the cylinder head cover.

Attach the clamp.

Connect the mass air flow meter connector.

Attach the 4 clips to install the cover.

NOTICE:

1. Be sure to attach the clips securely.
   
2. Do not apply excessive force or do not hit the cover to attach the clips. This may cause the cover to break.
   

Tighten the radiator drain cock plug by hand.

Add TOYOTA Super Long Life Coolant (SLLC) to the radiator reservoir filler opening until it is filled to the B line at the base of the reservoir filler neck.

HINT:

The B line is the lower edge of the inner wall of the filler neck.

Standard capacity:

Item	Specified Condition
for Manual Transaxle	5.8 liters (6.1 US qts, 5.1 Imp. qts)
for CVT	6.0 liters (6.3 US qts, 5.3 Imp. qts)

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).

NOTICE:

Never use water as a substitute for engine coolant.

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

Install the radiator reservoir cap.

Start the engine and warm it up until the cooling fan operates.

1. Set the air conditioning as follows while warming up the engine.
   
   

   Measurement condition

   Item	Condition
   Manual Air Conditioning System	Fan speed: Any setting except off Temperature: Toward WARM Air conditioning switch: Off
   Automatic Air Conditioning System	Temperature: Toward MAX (HOT) Air conditioning switch: Off

2. Maintain the engine speed at 2000 to 2500 rpm and warm up the engine until the cooling fan operates.
   

   NOTICE:

   1. Make sure that the radiator reservoir still has some coolant in it.
      
   2. Pay attention to the needle of the coolant temperature meter. Make sure that the needle does not show an abnormally high temperature.
      
   3. If there is not enough coolant, the engine may burn out or overheat.
      
   4. 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 B line.
      
   5. Run the engine at 2000 rpm until the coolant level has stabilized.
      

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

CAUTION:

When pressing the radiator hoses:

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

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

Check that the coolant level is between the FULL and LOW lines. If the coolant level is below the LOW line, repeat all of the procedures above.
If the coolant level is above the FULL line, drain coolant so that the coolant level is between the FULL and LOW lines.

Remove the radiator reservoir cap.

CAUTION:

To avoid the danger of being burned, do not remove the radiator reservoir cap while the engine and radiator are still hot. Thermal expansion will cause hot engine coolant and steam to blow out from the radiator reservoir.

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

Warm up the engine.

Pump the radiator cap 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 and water pump for leakage.
If there are no signs of external coolant leaks, check the heater core, cylinder block and head.

Reinstall the radiator reservoir cap.

Install the under cover with the 6 screws and 10 clips.

Disconnect the EFI MAIN and ETCS fuses at the same time. Wait at least 60 seconds, and then reconnect the fuses.

Turn the ignition switch to ON without operating the accelerator pedal.

NOTICE:

If the accelerator pedal is operated, perform the above steps again.

Connect the intelligent tester to the DLC3 and clear the DTCs (RAV4_ACA30 RM000000PDK0M7X.html).

Start the engine and check that the MIL is not illuminated and that the idle speed is within the specified range when the A/C is switched off after the engine is warmed up.

Engine Idle Speed:

Item	Specified Condition
for Manual Transaxle	580 to 680 rpm
for CVT	600 to 700 rpm

NOTICE:

1. Be sure to perform this step with all accessories off.
   
2. Make sure that the shift lever is in neutral (for Manual Transaxle), or N or P (for CVT).
   

Enter the following menus: Powertrain / Engine and ECT / Data List / All Data / Throttle Sensor Position. Fully depress the accelerator pedal and check that the value is 60% or more.

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