DRAIN ENGINE COOLANT

CAUTION:

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

Loosen the radiator drain cock plug.

*1 Vent Plug

Remove the radiator reservoir cap, and using a 6 mm hexagon wrench, remove the vent plug.
Drain the coolant.
Loosen the 2 cylinder block drain cock plugs.

ADD ENGINE COOLANT
CAUTION:

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

Tech Tips

Before adding coolant, turn the A/C switch off.

Total capacity

11.1 liters (11.7 US qts, 9.8 Imp. qts)
1. Tighten the radiator drain cock plug.
2. Tighten the 2 cylinder block drain cock plugs.
  
  Torque:
  
  13 N*m { 133 kgf*cm, 10 ft.*lbf }
3. Add TOYOTA Super Long Life Coolant (SLLC) into the radiator reservoir.
  
  Capacity
  
  5.0 liters (5.3 US qts, 4.4 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 consists of a combination of low phosphates and organic acids).
4. Further add coolant into the reservoir until it reaches the FULL line.
5. 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.
6. Using a 6 mm hexagon wrench, install the vent plug.
  
  Torque:
  
  1.5 N*m { 15 kgf*cm, 13 in.*lbf }
7. Bleed air from the cooling system.
  
  Tech Tips
  
  Before starting the engine to warm up the engine, turn the A/C switch off.
  1. Put the engine in inspection mode Click here.
  2. While idling the engine for approximately 10 minutes, make sure the coolant remains at the FULL line by adding coolant as necessary.
  3. After idling the engine for 10 minutes, add coolant until it reaches the B line.
    
    Capacity
    
    2.5 to 3.5 liters (2.6 to 3.7 US qts, 2.2 to 3.1 Imp. qts)

    B Line
    
    Tech Tips
    
    The B line is the lower edge of the inner wall of the filler neck.
  4. Close the radiator reservoir cap, and run the engine at 1500 to 2000 rpm for 5 minutes.
    
    CAUTION:
    
    Wear protective gloves.
    
    Be careful as the radiator hose is hot.
    
    Keep your hands away from the radiator fan.
    
    Tech Tips
    
    The thermostat open timing can be confirmed by pressing the No. 1 radiator hose by hand, and checking when the SLLC starts to flow inside the hose.
8. Stop the engine and wait until the coolant cools down to ambient temperature.
9. Check the coolant level.
  
  If the coolant level is below the FULL line, add coolant until it reaches the FULL line.
INSPECT FOR COOLANT LEAK

CAUTION:

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

Note

Before each inspection, turn the A/C switch OFF.
1. Fill the radiator with coolant and attach a radiator cap tester.
2. Warm up the engine.
3. Using the radiator cap tester, increase the pressure inside the radiator to 118 kPa (1.2 kgf/cm², 17 psi), and check that the pressure does not drop.
  
  If the pressure drops, check the hoses, radiator and engine water pump for leaks. If no external leaks are found, check the heater core, cylinder block and head.
INSTALL NO. 1 ENGINE UNDER COVER
1. Install the No. 1 engine under cover with the 13 screws and 7 clips.
INSTALL FRONT WHEEL OPENING EXTENSION PAD LH
1. Install the front wheel opening extension pad LH with the 5 screws.
INSTALL FRONT WHEEL OPENING EXTENSION PAD RH

Tech Tips

Use the same procedure described for the LH side.
INSTALL NO. 1 AIR CLEANER INLET
1. Align the holes with the connection areas labeled A, and attach the No. 1 air cleaner inlet.
2. Install the No. 1 air cleaner inlet with the 2 bolts.
  
  Torque:
  
  5.0 N*m { 51 kgf*cm, 44 in.*lbf }
INSTALL AIR CLEANER INLET COVER SUB-ASSEMBLY
1. Attach the 4 clips labeled B.
  Note
  
  Make sure the clips are attached securely.
  
  Attaching the clips forcefully or hitting the top of the clips may damage them.
2. Install the air cleaner inlet cover sub-assembly with the 5 clips labeled A.
INSTALL V-BANK COVER SUB-ASSEMBLY
1. After sliding the V-bank cover sub-assembly from the vehicle front to the rear to attach the 2 clips labeled A, attach the 4 clips labeled B and install the V-bank cover sub-assembly.
  CAUTION:
  
  Make sure the clips are attached securely.
  
  Attaching the clips forcefully or hitting the top of the clips may damage them.
