THERMOSTAT INSTALLATION

INSTALL V-RIBBED BELT

1. 

   Install the V-ribbed belt.

   Table 2. Text in Illustration

   *1	Water Pump
   *2	Idler
   *3	Crankshaft

2. 

   Turn the V-ribbed belt tensioner counterclockwise and remove a 5 mm bi-hexagon wrench.

3. After installing the V-ribbed belt, check that it fits properly in the ribbed grooves. Confirm that the belt has not slipped out of the grooves on the bottom of the crank pulley by hand.

INSTALL V-BANK COVER SUB-ASSEMBLY

1. 

   Engage the 4 retainers and install the V-bank cover sub-assembly.

INSTALL COOL AIR INTAKE DUCT SEAL

1. 

   Install the cool air intake duct seal with the 6 clips.

INSTALL ENGINE ROOM SIDE COVER

1. 

   Install the engine room side cover with the 4 clips.

INSTALL ENGINE ROOM SIDE COVER LH

1. 

   Install the engine room side cover LH with the 4 clips.

ADD COOLANT (for Engine)

1. Tighten the radiator drain cock plug by hand.

2. Tighten the cylinder block drain cock plug. (for Bank 1)

4. Loosen the air drain cock plug on the water inlet housing.

5. Add engine coolant to the radiator inlet opening until engine coolant overflows from the air drain cock hole. Then tighten the air drain cock plug to the water inlet housing.

6. Slowly fill the radiator assembly with engine coolant.

   Table 3. Standard Capacity

   Item	Capacity
   Engine coolant	11.7 liters (12.4 US qts, 10.2 lmp. qts)

   Note:

   Never use water as a substitute for engine coolant.

   Tip:

   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).

7. Remove the reserve tank cap.

8. 

   Slowly pour engine coolant into the radiator reserve tank assembly until it reaches the full line.

   Full Line

9. Squeeze the No. 1 radiator hose and No. 2 radiator hose several times by hand, and then check the level of the engine coolant.

   If the engine coolant level is low, add engine coolant.

10. Install the radiator cap sub-assembly and reserve tank cap.

11. Bleed air from the cooling system.

    
    

    1. Put the engine in inspection mode (Click here).

    2. Warm up the engine until the thermostat opens. While the thermostat is open, circulate the engine coolant for several minutes.

       Tip:

       The thermostat open timing can be confirmed by squeezing the No. 2 radiator hose by hand, and sensing vibrations when the engine coolant starts to flow inside the No. 2 radiator hose.

    3. Maintain the engine speed at 2500 rpm.

    4. Squeeze the No. 1 radiator hose and No. 2 radiator hose several times by hand to bleed air.

       CAUTION:

       When squeezing the No. 1 radiator hose and No. 2 radiator hose:

       
       

       • Wear protective gloves.

       • Be careful as the No. 1 radiator hose and No. 2 radiator hose are hot.

       • Keep your hands away from the fan and No. 2 fan.

       Note:
       

       • If the coolant temperature gauge indicates an excessive temperature, turn off the engine and let it cool.

       • Make sure that the radiator reserve tank assembly still has some engine coolant in it.

       • If the radiator reserve tank assembly does not have enough engine coolant, the engine may overheat or be seriously damaged.

       • If the radiator reserve tank assembly does not have enough engine coolant, perform the following: 1) stop the engine, 2) wait until the engine coolant has cooled down, and 3) add engine coolant until the radiator reserve tank assembly is filled to the full line.

12. Stop the engine, and wait until the engine coolant cools down.

13. Add engine coolant to the full line on the radiator reserve tank assembly.

INSPECT FOR COOLANT LEAK (for Engine)

1. Remove the radiator cap.

2. 

   Fill the radiator with coolant and attach a radiator cap tester.

3. Put the engine in inspection mode (Click here).

4. Warm up the engine.

5. 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, exhaust center pipe assembly and the heater hose around the water temperature switch and engine water pump for leaks. If no external leaks are found, check the heater core, cylinder block and cylinder head.

6. Remove the radiator cap tester.

7. Install the radiator cap.
