  Never use water as a substitute for engine coolant.
  
  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).
4. Remove the 2-way that is located near the throttle body assembly.
5. When air is bleed and the engine coolant drains out, install the 2-way.
6. Add coolant through the radiator reservoir assembly filler opening until the coolant reaches the B line and install the radiator reservoir cap sub-assembly. [*1]
7. Warm up the engine until the thermostat opens. While the thermostat is open, circulate the coolant for several minutes. [*2]
  CAUTION:
  - Wear protective gloves.
  - Be careful as the radiator hoses are hot.
  - Keep your hands away from the radiator fans.
  Note
  - Immediately after starting the engine, if the radiator reservoir assembly does not have any engine coolant, perform the following: 1) stop the engine, 2) wait until the engine coolant has cooled down, and 3) add engine coolant.
  - Do not start the engine when there is no engine coolant in the radiator reservoir assembly.
  - Make sure that the needle does not show an abnormally high temperature.
  - If there is not enough engine coolant, the engine may overheat.
  Tech Tips
  - Press the No. 2 and No. 3 radiator hoses several times by hand, and then check the level of the engine coolant.
  - The thermostat open timing can be confirmed by pressing the No. 3 radiator hose by hand, and checking when the engine coolant starts to flow inside the hose.
8. Stop the engine, and wait until the engine coolant cools down to ambient temperature. [*3]
9. Check the engine coolant level in the radiator reservoir assembly. [*4]
  Tech Tips
  - If the engine coolant level is below the LOW line, repeat steps *1 through *4.
  - If the engine coolant level is above the FULL line, drain engine coolant until the engine coolant level is between the FULL and LOW line.
INSPECT FOR FUEL LEAK
1. Check that there are no fuel leaks after performing maintenance anywhere on the fuel system.
  
  If there are fuel leaks, repair or replace parts as necessary.
INSPECT FOR OIL LEAK
1. Start the engine. Make sure that there are no oil leaks from the areas that were worked on.
CHECK AUTOMATIC TRANSMISSION FLUID LEVEL
Tech Tips
- Drive the vehicle so that the engine and transmission are at the normal operating temperature.
  
  ATF temperature
  
  70 to 80°C (158 to 176°F)
- The ATF temperature can be checked with the intelligent tester.
  
  Enter the following menus: Powertrain / Engine and ECT / Data List / A/T Oil Temperature 3.

  Park the vehicle on a level surface and set the parking brake.
2. With the engine idling and the brake pedal depressed, move the shift lever to all positions from P to L, and then return it to P.
3. Pull out the dipstick and wipe it clean.
4. Fully push the dipstick back into the pipe.
5. Pull the dipstick out and check that the fluid level is in the HOT range.
  
  If there are leaks, it is necessary to repair or replace O-rings, seal packing, oil seals, plugs or other parts.
INSPECT FOR COOLANT LEAKS

CAUTION:

Do not remove the radiator reservoir cap sub-assembly while the engine and radiator are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.
1. Remove the radiator reservoir cap sub-assembly.
2. Fill the radiator reservoir assembly with engine coolant, and then attach a radiator cap tester.
3. Warm up the engine.
4. Using the radiator cap tester, increase the pressure inside the radiator to 137 kPa (1.4 kgf/cm², 20 psi), and then check that the pressure does not drop.
  
  If the pressure drops, check the hoses, radiator assembly and engine water pump assembly for leakage.
  
  If there are no signs or traces of external engine coolant leakage, check the heater core, cylinder block assembly and cylinder head sub-assembly.
5. Install the radiator reservoir cap sub-assembly.
ADJUST SHIFT LEVER POSITION
1. Remove a clip, nut, and disconnect between the control shaft lever to transmission control cable assembly from the control shaft lever and transmission control cable bracket No. 1.
2. Turn the control shaft lever until stop to a clockwise direction, return the control shaft lever 2 notches to N position.
3. Set the shift lever to N position while holding the shift lever lightly toward the R position side and install it.
  
  Torque:
  
  15 N*m { 150 kgf*cm, 11 ft.*lbf }
4. Inspect the operation condition and work.
INSPECT SHIFT LEVER POSITION
1. When shifting from P position only with ignition switch ON and depress the break pedal.
2. Make sure that the shifting lever moves smoothly and can be moderately operated.
3. When starting engine, make sure that the vehicle moves forward when shifting from N to D position and moves reward when shifting R position.

INSPECT IGNITION TIMING

Warm up and stop the engine.

Note

A warmed up engine should have an engine coolant temperature of over 80°C (176°F), have an engine oil temperature of 60°C (140°F), and the engine speed should be stabilized.
When using the intelligent tester:
1. Connect the intelligent tester to the DLC3.
2. Start the engine and idle it.
3. Turn the intelligent tester main switch on.
4. Enter the following menus:
  
  Powertrain / Engine and ECT / Data List / IGN Advance
  
  Standard ignition timing
  
  5 to 15° BTDC at idle
  
  Note
  
  When checking the ignition timing, the transmission should be in neutral or park.
  
  Tech Tips
  
  Refer to the intelligent tester operator's manual for further detail.

Standard ignition timing
5 to 15° BTDC at idle

When not using the intelligent tester:

Connect the tester probe of a timing light to the wire of the ignition coil connector for the No.4 cylinder.
Note
- Use a timing light that detects primary signals.
- After checking, be sure to wrap the wire harness with tape.
Start the engine and idle it.

Using SST, connect terminals 13 (TC) and 4 (CG) of the DLC3.

Note

Confirm the terminal numbers before connecting them. Connecting the wrong terminals can damage the engine.
When checking the ignition timing, the transmission should be in neutral or park.

Tech Tips

After connecting terminals (TC and CG), engine speed changes to approximately 1000 to 1500 rpm for 5 seconds, and then returns to idle speed. This is because the ECM checks that the ISC (idle speed control system) operates properly.
Perform the inspection of the ignition timing after engine speed is returned to idle speed.
