Using SST, hold the water pump pulley.
Using SST and union nut wrench, tighten the 4 bolts.
Note
The "with SST" torque value is effective when using SST with a fulcrum length of 170 mm (6.69 in.) and a torque wrench with a fulcrum length of 180 mm (7.09 in.) Click here.
The "with SST" torque value is effective when SST is parallel to the torque wrench.

| *1 | Dust Shield |
| *2 | Pulley |
| *a | Correct |
| *b | Incorrect |
Install the V-ribbed belt tensioner pulley and dust shield with the bolt.
Note
Be careful when tightening the bolt because its thread is left-handed.
Install the dust shield in the direction shown in the illustration. Failure to do so may cause looseness.
Make sure to use the removed bolt. (Do not use another bolt even if it is the same size.)
Install the 5 mm bi-hexagon wrench.
INSTALL NO. 2 IDLER PULLEY SUB-ASSEMBLY
Install the idler pulley cover plate, No. 2 idler pulley sub-assembly and No. 2 idler pulley cover plate with the bolt.
INSTALL FRONT NO. 1 ENGINE MOUNTING BRACKET LH
Temporarily install the front No. 1 engine mounting bracket LH with the 6 bolts.
Fully tighten the 5 bolts.
| *a | 150 mm |
Using SST, fully tighten the bolt.
Note
The "with SST" torque value is effective when using SST with a fulcrum length of 150 mm (5.905 in.) and a torque wrench with a fulcrum length of 260 mm (10.23 in.) Click here.
The "with SST" torque value is effective when SST is parallel to the torque wrench.
INSTALL ENGINE MOVING CONTROL ROD BRACKET
When replacing the engine moving control rod.
Install the engine moving control rod bracket with engine moving control rod with the 4 bolts.
Note
Temporarily tighten bolt A and B, and then fully tighten the 4 bolts in the order of C, D, A and B.
Tighten the bolt E.
When not replacing the engine moving control rod.
Install the engine moving control rod bracket with engine moving control rod with the 4 bolts.
Note
Temporarily tighten bolt A and B, and then fully tighten the 4 bolts in the order of C, D, A and B.
INSTALL NO. 2 ENGINE MOUNTING STAY RH (for Intake Manifold Side)
Install the No. 2 engine mounting stay RH with the bolt.
INSTALL NO. 2 ENGINE MOUNTING STAY RH (for Engine Mounting stay Side)
Install the No. 2 engine mounting stay RH with the bolt.
Tighten the 2 nuts.
CONNECT NO. 2 RADIATOR HOSE
Connect the No. 2 radiator hose with the hose clip.
INSTALL V-RIBBED BELT
ADD ENGINE COOLANT
Tighten the radiator drain cock plug by hand.
Close the 2 cylinder block drain cock plugs.
Loosen the air drain cock plug on the water inlet housing.
Add TOYOTA Super Long Life Coolant (SLLC) to the radiator inlet opening until coolant overflows from the air drain cock hole. Then tighten the air drain cock plug to the water inlet housing.
| *a | Code Mark |
Slowly fill the radiator with TOYOTA Super Long Life Coolant (SLLC).
| Code Mark "K" | 8.8 liters (9.3 US qts, 7.7 lmp. qts) |
| Code Mark "J" | 8.9 liters (9.4 US qts, 7.8 lmp. 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 is a combination of low phosphates and organic acids).
Slowly pour coolant into the radiator reserve tank assembly until it reaches the full line.
Squeeze the No. 1 and No. 2 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 reserve tank cap.
Bleed air from the cooling system.
Note
Before starting the engine, turn the A/C switch off.
Adjust the heater control to the maximum hot setting.
Adjust the blower speed to the low setting.
Warm up the engine until the thermostat opens. While the thermostat is open, circulate the coolant for several minutes.
Tech Tips
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 hose.
Maintain the engine speed at 2500 to 3000 rpm.
Squeeze the No. 1 and No. 2 radiator hoses several times by hand to bleed air.
CAUTION:
When squeezing the radiator hoses:
Wear protective gloves.
Be careful as the radiator hoses are hot.
Keep your hands away from the radiator fans.
Note
Make sure that the radiator reserve tank assembly still has some coolant in it.
If the coolant temperature gauge indicates an excessive temperature, turn off the engine and let it cool.
If there is not enough coolant, the engine may overheat or be seriously damaged.
If the radiator reserve tank assembly does not have enough coolant, perform the following: 1) stop the engine, 2) wait until the coolant has cooled down, and 3) add coolant until the reserve tank assembly is filled to the full line.
Stop the engine, and wait until the engine coolant cools down.
Add engine coolant to the full line on the radiator reserve tank assembly.
INSPECT FOR COOLANT LEAK
CAUTION:
Do not remove the radiator cap sub-assembly while the engine and radiator are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.
Note
Before performing each inspection, turn the A/C switch OFF.
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.
