Thermostat Installation

Install a new gasket to the thermostat.

HINT:

When installing the thermostat to the gasket, be careful not to deform the gasket. Make sure that the thermostat is properly installed into the groove of the gasket as shown in the illustration.

Insert the thermostat into the water inlet housing with the jiggle valve facing straight upward.

HINT:

The jiggle valve may be set within 30°of either side of the prescribed position.

Install the water inlet with the 3 nuts.

Torque:

19 N*m{194 kgf*cm, 14 ft.*lbf}

Tighten the radiator drain cock plug by hand.

Tighten the 2 cylinder block drain cock plugs.

Torque:

12.7 N*m{130 kgf*cm, 9 ft.*lbf}

Add engine coolant.

HINT:

Add engine coolant until coolant overflows from the vent plug.

Specified capacity:

11.0 liters (11.7 US qts, 9.7 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. Please contact your TOYOTA dealer for further details.
   

Install the vent plug.

Slowly pour coolant into the radiator reservoir 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.

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.
   

   HINT:

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

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.
   

   NOTICE:

   When pressing the radiator hoses:

   1. Wear protective gloves.
      
   1. Be careful as the radiator hoses are hot.
      
   1. Keep your hands away from the radiator fan.
      

Stop the engine, and wait until the engine 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.

Check the coolant level in the radiator reservoir.
If the coolant level is low, add SLLC to the radiator reservoir FULL line.

Install the connector pipe with the bolt and 2 hose clamps.

Torque:

4.0 N*m{41 kgf*cm, 35 ft.*lbf} for hose clamps

5.0 N*m{51 kgf*cm, 44 ft.*lbf} for bolt

Connect the air hose and No. 1 ventilation hose.

Install the inlet with the bolt.

Torque:

5.0 N*m{51 kgf*cm, 44 in.*lbf}

Install the duct seal with the 7 clips.

Install the cover with the 2 nuts.

Torque:

5.0 N*m{51 kgf*cm, 44 in.*lbf}

Install the under cover with the 3 clips and 10 screws.
