| Standard Capacity | ||||||
|---|---|---|---|---|---|---|
|
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 reservoir tank until it reaches the full line.
Press 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.
Bleed air from the cooling system.
Note
Before starting the engine to warm up the engine, turn the A/C switch off.
Warm up the engine until the thermostat opens. While the thermostat is open, circulate the coolant for several minutes.
CAUTION:
When pressing the radiator hoses:
Wear protective gloves.
Be careful as the radiator hoses are hot.
Keep your hands away from the radiator fans.
Tech Tips
The thermostat open timing can be confirmed by pressing the No. 1 radiator hose by hand, and checking when the engine coolant starts to flow inside the hose.
Maintain the engine speed at 2000 to 2500 rpm.
Press the No. 1 and No. 2 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 fans.
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 tank.
If the coolant level is low, add SLLC to the radiator reservoir tank full line.
INSPECT FOR COOLANT LEAK
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.
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 137 kPa (1.4 kgf/cm2, 20 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.

Tech Tips
Prepare a 10 m (32.8 ft.) string, a string with a sharp-pointed weight (plumb bob), and a 5 m (16.4 ft.) tape measure.
Place the reflector.
Hang the string (with weight) from the center of the vehicle's rear emblem. Mark the vehicle's rear center point on the ground. Repeat for the front of the vehicle.
| *a | Adjust Center By Moving String To Right And Left |
| *b | Extend String Through Front Center Mark |
Set one end of the 10 m (32.8 ft.) string on the vehicle's rear center point. Run the string over the vehicle's front center point to a position 5 m (16.4 ft.) beyond the vehicle's front center point as shown in the illustration. Mark the 5 m (16.4 ft.) position.
Place the reflector (SST) at the marked position.
