with rear heater	16.2 liters (17.1 US qts, 14.3 Imp. qts)
without rear heater	13.4 liters (14.2 US qts, 11.8 Imp. qts)

Note

Do not substitute plain water 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 consists of a combination of low phosphates and organic acids).

Slowly pour coolant into the radiator reservoir until it reaches the F line.
Install the reservoir cap.
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.
Install the radiator cap.
Start the engine and warm it up until the thermostat opens.

Tech Tips

The thermostat opening timing can be confirmed by pressing the radiator inlet hose by hand, and checking when the engine coolant starts to flow inside the hose.
Maintain the engine speed at 2000 to 2500 rpm.
Note
- Make sure that the radiator reservoir still has some coolant in it.
- Pay attention to the needle of the water temperature meter. Make sure that the needle does not show an abnormally high temperature.
- If there is not enough coolant, the engine may burn out or overheat.
- 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.
- 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:
- Wear protective gloves.
- Be careful as the radiator hoses are hot.
- Keep your hands away from the fan.
Stop the engine, and wait until the engine coolant cools down to ambient temperature.

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.
Check that the coolant level is between the F and L lines.

If the coolant level is below the L line, repeat all of the procedures above.

If the coolant level is above the F line, drain coolant so that the coolant level is between the F and L lines.

  When not using the intelligent tester:
  1. Using SST, connect the tachometer probe to terminal 9 (TAC) of the DLC3.
    
    SST
    
    09843-18030
    Note
    
    Confirm the terminal number before connecting the probe. Connecting the probe to the wrong terminal can damage the engine.
    
    Switch off all accessories and the A/C before connecting the probe.
  2. Race the engine at 2500 rpm for approximately 90 seconds.
  3. Check the idle speed.
    
    Standard idle speed
    
    650 to 750 rpm (transmission in neutral and A/C switch off)
    
    If the idle speed is not as specified, check the air intake system.
  4. Disconnect the tachometer probe from the DLC3.

INSPECT CO/HC

Tech Tips

This check is used only to determine whether or not the idle CO/HC complies with regulations.

Start the engine.
Keep the engine speed at 2500 rpm for approximately 180 seconds.
Insert the CO/HC meter testing probe at least 40 cm (1.31 ft.) into the tailpipe during idling.
Immediately check CO/HC concentration at idle and/or 2500 rpm.

Tech Tips

When performing the 2 mode (2500 rpm and idle) test, follow the measurement order prescribed by the applicable local regulations.

If the CO/HC concentration does not comply with the regulations, troubleshoot in the order given below.

Check the A/F sensor Click here and heated oxygen sensor Click here operation.

See the table below for possible causes, and then inspect and correct the applicable causes if necessary.

CO	HC	Symptom	Cause
Normal	High	Rough idle	Faulty ignitions: Incorrect timing Plugs (contaminated, shorted or gaps are defective) Incorrect valve clearance Leaky intake and exhaust valves Leaky cylinder
Low	High	Rough idle (Fluctuating HC reading)	Vacuum leaks: PCV hose Intake manifold Throttle body Lean mixture causing misfire
High	High	Rough idle (Black smoke from exhaust)	Restricted air filter Faulty SFI system: Faulty pressure regulator Defective engine coolant temperature sensor Faulty ECM Faulty injectors Faulty throttle position sensor Faulty mass air flow meter

INSPECT ENGINE OIL LEVEL

Warm up the engine. Then stop the engine and wait for 5 minutes.

*a	Measuring Surface
*b	Low Level Mark
*c	Full Level Mark

Check that the engine oil level is between the dipstick low level mark and full level mark.

If the level is low, check for leakage and add oil up to the full level mark.

Note

Do not fill engine oil above the full level mark.

Tech Tips

A certain amount of engine oil will be consumed while driving. In the following situations, oil consumption may increase, and engine oil may need to be refilled in between oil maintenance intervals.

When the engine is new, for example directly after purchasing the vehicle or after replacing the engine.
If low quality oil or oil of an inappropriate viscosity is used.
When driving at high engine speed or with a heavy load, (when towing, or), when driving while accelerating or decelerating frequently.
When leaving the idling for a long time, or when driving frequently through heavy traffic.

When judging the amount of oil consumption, keep in mind that the oil may have become diluted, making it difficult to judge the true level accurately.

INSPECT ENGINE COOLANT LEVEL
1. Check that the engine coolant level is between the L and F lines when the engine is cold.
  
  If the engine coolant is below the L line, check for leaks and add "TOYOTA Super Long Life Coolant" or similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite and non-borate coolant with long-life hybrid organic acid technology to the F line.
  
  Note
  
  Do not substitute plain water for engine coolant.
