Install a new gasket to the thermostat.
Note
When installing the gasket to the thermostat, be careful not to deform the gasket. Make sure that the groove of the gasket is properly installed to the thermostat as shown in the illustration.
Insert the thermostat into the cylinder block with the jiggle valve facing straight upward.
Tech Tips
The jiggle valve may be set within 30° of either side of the prescribed position.
INSTALL WATER INLET
Install the wire harness clamp bracket to the water inlet with the bolt.
Install the water inlet with the 3 bolts.
Connect the wire harness clamp.
CONNECT RADIATOR HOSE OUTLET
Connect the radiator hose outlet to the water inlet.
INSTALL COMPRESSOR INLET ELBOW
Install a new gasket and the compressor inlet elbow with the 2 nuts.
Attach the wire harness clamp and connect the 2 connectors.
INSTALL AIR CLEANER ASSEMBLY
Install the air cleaner together with the No. 1 air cleaner hose with the 2 bolts.
Connect the No. 1 air cleaner hose and tighten the hose clamp of the compressor inlet elbow.
Install the ventilation hose and attach the ventilation hose clamp.
Connect the mass air flow meter connector and attach the wire harness clamp.
ADD ENGINE COOLANT
Tighten the cylinder block drain cock plug.
Tighten the radiator drain cock plug by hand.
Fill the radiator with TOYOTA Super Long Life Coolant (SLLC) to the reservoir tank's B line.

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 consists of a combination of low phosphates and organic acids).
Note
Never use water as a substitute for engine coolant.
Press the inlet and outlet radiator hoses several times by hand, and then check the level of the coolant.
If the coolant level drops below the B line, add TOYOTA SLLC to the B line.
Install the radiator reservoir cap.
Using a wrench, install the vent plug.
Bleed air from the cooling system.
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 pressing the inlet radiator hose by hand, and checking when the engine coolant starts to flow inside the hose.
Maintain the engine speed at 2500 to 3000 rpm.
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.
Stop the engine and wait until the coolant cools down to ambient temperature.
CAUTION:
Do not remove the radiator reservoir cap while the engine and radiator are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.
After the coolant cools down, check that the coolant level is at the F line.
If the coolant level is below the F line, add TOYOTA SLLC to the F line.
INSPECT FOR COOLANT LEAK
Note
Do not remove the radiator reservoir cap while the engine and radiator are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.
Fill the radiator with coolant and attach a radiator cap tester to the radiator reservoir.
Warm up the engine.
Using a 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.
