| Standard Capacity | ||||||
|---|---|---|---|---|---|---|
|
Note
Never use water as a substitute for engine coolant.
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).
Remove the 2-way that is located near the throttle body assembly.
When air is bled and the engine coolant drains out, install the 2-way.
Add coolant through the radiator reservoir assembly filler opening until the coolant reaches the B line and install the radiator reservoir cap sub-assembly. [*1]
Warm up the engine until the thermostat opens. While the thermostat is open, circulate the coolant for several minutes. [*2]
CAUTION:
Wear protective gloves.
Be careful as the radiator hoses are hot.
Keep your hands away from the radiator fans.
Note
Immediately after starting the engine, if the radiator reservoir assembly does not have any engine coolant, perform the following: 1) stop the engine, 2) wait until the engine coolant has cooled down, and 3) add engine coolant.
Do not start the engine when there is no engine coolant in the radiator reservoir assembly.
Make sure that the needle does not show an abnormally high temperature.
If there is not enough engine coolant, the engine may overheat.
Tech Tips
Press the No. 2 and No. 3 radiator hoses several times by hand, and then check the level of the engine coolant.
The thermostat open timing can be confirmed by pressing the No. 3 radiator hose by hand, and checking when the engine coolant starts to flow inside the hose.
Stop the engine, and wait until the engine coolant cools down to ambient temperature. [*3]
Check the engine coolant level in the radiator reservoir assembly. [*4]
Tech Tips
If the engine coolant level is below the LOW line, repeat step *1 through *4.
If the engine coolant level is above the FULL line, drain engine coolant until the engine coolant level is between the FULL and LOW lines.
INSPECT FOR FUEL LEAKS
When using the intelligent tester
Connect the intelligent tester to the DLC3.
Turn the ignition switch to the on position and intelligent tester main switch ON.
Note
Do not start the engine.

Tech Tips
Please refer to the intelligent tester operator's manual for further details.
When not using the intelligent tester.
Disconnect the fuel pump connector.
Using a service wire, connect terminals FP and +B of the relay block.
Note
Pay attention to the terminal connecting position to avoid a malfunction.
Turn the ignition switch to the ON position, and check that the fuel pump operates.
Note
Do not start the engine.

Check that the pulsation damper screw rises up when the fuel pump operates.
If operation is not as specified, check the following parts:
Fusible link
Fuel pump
Wiring connections
ECM
Fuses
Turn the ignition switch off.
Disconnect the intelligent tester from the DLC3.
INSPECT ENGINE OIL LEAKS
CHECK FOR ENGINE COOLANT LEAKS
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.
Fill the radiator with coolant and attach a radiator cap tester to the radiator.
Warm up the engine.
Using a radiator cap tester, increase the pressure inside the radiator to 137 kPa (1.4 kgf/cm2, 19.9 psi), and check that the pressure does not drop.
Tech Tips
If the pressure drops, check the hoses, radiator or water pump for leaks. If no external leaks are found, check the heater core, cylinder block and cylinder head.
