Thermostat Installation

Install a new gasket to the thermostat.

Install the thermostat with the jiggle valve facing up.

HINT:

The jiggle valve may be set within 10°on either side of the prescribed position.

Install the water inlet with the 2 nuts .

Torque:

10 N*m{102 kgf*cm, 7 ft.*lbf}

Connect the radiator hose outlet to the radiator assembly.

Install the No. 2 idler pulley sub-assembly and cover plate with the bolt.

Torque:

43 N*m{438 kgf*cm, 32 ft.*lbf}

Install the V-ribbed belt.

Using SST, turn the belt tensioner counterclockwise and remove the bar.

SST

09249-63010

If it is difficult to install the V-ribbed belt, perform the following procedure:

1. Put the V-ribbed belt on every pulley except the tensioner pulley as shown in the illustration.
   

2. While releasing the belt tension by turning the belt tensioner counterclockwise, put the V-ribbed belt on the tensioner pulley.
   

   NOTICE:

   1. Put the backside of the V-ribbed belt on the tensioner pulley and idler pulley.
      
   2. Check that the V-ribbed belt is properly set to each pulley.
      

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.
   

Temporarily install the engine moving control rod with the 4 bolts.

First install the bolts A, and then the remaining bolt B.

Torque:

38 N*m{388 kgf*cm, 28 ft.*lbf}

Install the No. 2 mounting stay RH with the bolt.

Torque:

21 N*m{214 kgf*cm, 15 ft.*lbf}

Close the radiator drain cock plug and 2 cylinder block drain cock plugs.

Torque:

13 N*m{130 kgf*cm, 9 ft.*lbf} for cylinder block drain cock plug

Slowly fill the radiator with TOYOTA Super Long Life Coolant (SLLC).

Specified capacity:

9.0 liters (9.5 US qts, 7.9 lmp. qts)

HINT:

1. 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).
   

1. Contact your TOYOTA dealer for further details.
   

Slowly pour coolant into the radiator reservoir tank until it reaches the FULL line.

Press the inlet and outlet radiator hoses several times by hand, and then check the level of the coolant.
If the coolant level is low, add coolant.

Install the radiator cap sub-assembly and reservoir tank cap.

Start the engine, and warm it up.

HINT:

Adjust the air conditioner set temperature to MAX (HOT).

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

Add engine coolant to the FULL line on the radiator reservoir.

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

Warm up the engine.

Using a radiator cap tester, increase the pressure inside the radiator to 118 kPa (1.2 kgf*cm, 17 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 heater core, cylinder block and cylinder head.

Fit the 3 retainers and install the V-bank cover.
