INSTALL THROTTLE BODY ASSEMBLY
Install a new gasket to the intake manifold.
Install the throttle body with the 2 bolts and 2 nuts.
Connect the throttle body connector and 2 water hoses.
INSTALL AIR CLEANER CAP SUB-ASSEMBLY
Connect the air cleaner cap with the band.
Connect the ventilation hose.
Connect the 2 clamps.
Attach the wire harness to the 2 clamps.
Connect the mass air flow meter connector.
INSTALL NO. 2 CYLINDER HEAD COVER
Attach the 4 clips to install the cover.
Note
Be sure to attach the clips securely.
Do not apply excessive force or hit the cover to attach the clips. This may cause the cover to break.
ADD ENGINE COOLANT
Tighten the radiator drain cock plug.
Tighten the cylinder block drain cock plug.
Add TOYOTA Super Long Life Coolant (SLLC) through the radiator reservoir filler opening until the coolant reaches the B line.
Standard Capacity |
---|
6.3 liters (6.7 US qts, 5.5 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.
Install the cap and warm up the engine sufficiently.
Bleed air from the cooling system.
Note
Before starting the engine, turn the A/C switch off.
Adjust the air conditioning temperature setting to MAX (HOT).
Adjust the air conditioning blower setting to Lo.
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.
After the engine has warmed up, repeat the following procedure for at least 7 minutes: run the engine at 3000 rpm for 5 seconds, and then at idle speed for 45 seconds (repeat this procedure at least 8 times).
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.
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.
INSPECT FOR COOLANT LEAK
CAUTION:
To avoid being burned, do not remove the reserve tank cap while the engine and radiator are still hot. Thermal expansion may cause hot engine coolant and steam to blow out from the radiator.
Fill the radiator with engine coolant, and then attach a radiator cap tester.
Warm up the engine.
Using the radiator cap tester, increase the pressure inside the radiator to 118 kPa (1.2 kgf/cm2, 17 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 or traces of external engine coolant leakage, check the heater core, cylinder block and head.
CONNECT CABLE TO NEGATIVE BATTERY TERMINAL
Note
When disconnecting the cable, some systems need to be initialized after the cable is reconnected Click here.
INSTALL RADIATOR SUPPORT OPENING COVER
Install the radiator support opening cover with the 8 clips.
INSTALL ENGINE ROOM SIDE COVER
Install the engine room side cover with the clip.
PERFORM INITIALIZATION
Note
Be sure to perform this procedure after reassembling the throttle body assembly or removing and reinstalling any throttle body component.
Perform the following procedure after replacing the ECM, throttle body assembly or any throttle body components. The following procedure should also be performed if the throttle body is cleaned.
Be sure to perform this procedure after replacing the ECM and reconnecting the battery cable.
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.
Note
If the accelerator pedal is operated, perform the above steps again.
Connect the intelligent tester to the DLC3 and clear the DTCs Click here.
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.
Standard idle speed |
---|
580 to 680 rpm |
Note
Be sure to perform this step with all accessories off.
Make sure that the shift lever is in neutral.
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.
