Add engine coolant.
| Standard capacity |
|---|
| 8.6 liters (9.1 US qts, 7.6 Imp. qts) |
Note
Do not substitute plain water 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).
Squeeze the No. 1 radiator hose and No. 2 radiator hose several times by hand, and then check the level of the engine coolant.
If the engine coolant level is low, add engine coolant.
| *a | B Line |
Continue adding engine coolant until it reaches the B line. (*1)
Install the reserve tank cap. (*2)
Run the engine at about 2000 rpm to warm it up until the thermostat opens. While the thermostat is open, circulate the engine coolant for several minutes. (*3)
CAUTION:
Wear protective gloves.
Be careful as the No. 1 radiator hose and No. 2 radiator hose are hot.
Keep your hands away from the fan and No. 2 fan.
Note
If the radiator reserve tank runs out of engine coolant just after the engine is started, stop the engine immediately, wait until the engine coolant has cooled down, and then add engine coolant.
Make sure that the radiator reserve tank still has some engine 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 engine coolant, the engine may overheat or be seriously damaged.
Stop the engine and wait until the engine coolant cools down. (*4)
| *a | Full Line |
| *b | Low Line |
Check that the engine coolant level is between the full line and low line. (*5)
Tech Tips
If the engine coolant level is below the low line, remove the reserve tank cap and repeat steps from (*1) to (*5).
If the engine coolant level is above the full line, drain engine coolant so that the engine coolant level is between the full line and low line.
INSPECT FOR COOLANT LEAK
Remove the reserve tank cap.
CAUTION:
Do not remove the reserve tank cap while the engine and radiator are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.
| *1 | Radiator Cap Tester |
Fill the radiator and radiator reserve tank with coolant, and then attach a radiator cap tester.
Warm up the engine.
Pump the radiator cap tester to 118 kPa (1.2 kgf/cm2, 17 psi), and then check that the pressure does not drop.
If the pressure drops, check the hoses, radiator and water pump for leaks.
If there are no signs of external coolant leaks, check the heater core, cylinder block and head.
Reinstall the reserve tank cap.
