NOTICE:

Do not substitute plain water for engine coolant.

HINT:

1. 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).
   
2. Press the No. 1 and No. 2 radiator hoses several times by hand, and then check the coolant level. If the coolant level is low, add coolant.
   

Slowly pour coolant into the radiator reservoir until it reaches the F line.

Install the reservoir cap.

Install the radiator cap.*1

Start the engine and stop it immediately.*2

Allow approximately 10 seconds to pass. Then remove the radiator cap and check the coolant level. If the coolant level has decreased, add coolant.*3

Repeat steps *1, *2 and *3 until the coolant level does not decrease.

HINT:

Be sure to perform this step while the engine is cold, as air in the No. 1 radiator hose will flow into the radiator if the engine is warmed up and the thermostat opens.

Install the radiator cap.*4

Set the air conditioning as follows.*5

Start the engine, warm it up until the thermostat opens, and then continue to run the engine for several minutes to circulate the coolant.*6

CAUTION:

1. Wear protective gloves. Hot areas on the parts may injure your hands.
   
2. Be careful of the fan.
   
3. Be careful as the engine, radiator and radiator hoses are hot and can cause burns.
   

NOTICE:

1. 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 F line.
   
2. Do not start the engine when there is no coolant in the radiator reservoir.
   
3. Pay attention to the needle of the engine coolant temperature receiver gauge. Make sure that the needle does not show an abnormally high temperature.
   
4. If there is not enough coolant, the engine may burn out or overheat.
   

HINT:

1. Press the No. 1 and No. 2 radiator hoses several times by hand to bleed air while warming up the engine.
   
2. 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, wait until the engine coolant cools down to ambient temperature. Then remove the radiator cap and check the coolant level.*7

CAUTION:

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

If the coolant level has decreased, add coolant and warm up the engine until the thermostat opens.*8

If the coolant level has not decreased, check that the coolant level in the radiator reservoir is at the F line.
If the coolant level is below the F line, repeat steps *4 through *8.
If the coolant level is above the F line, drain coolant until the coolant level reaches the F line.

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 123 kPa (1.3 kgf/cm², 18 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.

Hook the engine under cover to the vehicle body as shown in the illustration.

Install the 4 bolts.

Torque:

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

Install the front bumper cover lower with the 5 bolts and clip.

Torque:

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

Attach the 2 V-bank cover hooks to the bracket. Then align the 2 V-bank cover grommets with the 2 pins and press down on the V-bank cover to attach the pins.

Install the upper radiator support seal with the 13 clips.

for Manual Transmission:
Disconnect the EFI and ETCS fuses at the same time. Wait at least 60 seconds, and then reconnect the fuses.

Turn the engine switch on (IG) 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 (LandCruiser RM000000PDK1DIX.html).

for Automatic Transmission:
Perform "Inspection After Repairs" (LandCruiser RM000004NJC03SX.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.

Standard idle speed:

690 to 790 rpm

NOTICE:

1. Be sure to perform this step with all accessories off.
   
2. 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.
