CAMSHAFT (for Bank 2) INSTALLATION

INSTALL NO. 3 CAMSHAFT
Note

As the thrust clearance of the camshaft is small, the camshaft must be kept level while it is being installed. If the camshaft is not kept level, the portion of the cylinder head which receives the shaft thrust may crack or be damaged, causing the camshaft to seize or break. To avoid this, the following steps should be carried out.
1. Align the mark link (yellow) with the timing mark (2 dot marks) of the camshaft timing gear as shown in the illustration.
2. Apply new engine oil to the thrust portion and journal of the camshafts.
3. Temporarily put the No. 1 chain on the No. 2 chain of the camshaft timing gear.
4. Align the knock pin hole in the camshaft timing gear with the knock pin of the No. 3 camshaft, and insert the No. 3 camshaft into the camshaft timing gear.
5. Temporarily install the camshaft timing gear set bolt.
6. Set the No. 3 camshaft onto the LH cylinder head with the cam lobes of the No. 2 cylinder faced downward as shown in the illustration.

8. Apply a light coat of engine oil on the threads and under the heads of the bearing cap bolts.
9. Install and uniformly tighten the 8 bearing cap bolts in several passes in the sequence shown in the illustration.

ADD ENGINE COOLANT
1. Tighten all the plugs and fill the radiator with TOYOTA Super Long Life Coolant (SLLC).
  
  Torque:
  
  13 N*m { 130 kgf*cm, 9 ft.*lbf, for cylinder block drain cock plug }
  
  Standard Capacity
  
  9.8 liters (10.4 US qts, 8.6 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 and technology consists of a combination of low phosphates and organic acids).
  - Please contact your TOYOTA dealer for further details.
  Note
  
  Never use water as a substitute for engine coolant.
2. Press the inlet and outlet radiator hoses several times by hand, and then check the level of the coolant.
3. Install the radiator cap.
4. Bleed air from the cooling system.
  1. Warm up the engine until the thermostat opens. While the thermostat is open, circulate the coolant for several minutes.
  2. Maintain the engine speed at 2,000 to 2,500 rpm.
  3. Press the inlet and outlet radiator hoses several times by hand to bleed air.
    CAUTION:
    When pressing the radiator hoses:
    
    Wear protective gloves.
    
    Be careful as the radiator hoses are hot.
    
    Keep your hands away from the radiator fan.
5. Stop the engine and wait until the 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.
6. Check the coolant level in the radiator reservoir.
  
  If the coolant level is low, add SLLC to the reservoir F line.
CHECK FOR ENGINE COOLANT LEAKS
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.
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, 17.1 psi), and check that the pressure does not drop.
  
  If the pressure drops, check the hoses, radiator and water pump for leaks. If no external leaks are found, check the cylinder block and head.
INSTALL V-BANK COVER
1. Install the V-bank cover with the 2 nuts.
