If the coolant level drops within a short time after replenishing
Visually check the radiator, hoses, reservoir cap, radiator cap, drain cock
and water pump.
If you cannot find a leak, have any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional, test the cap and check for
leaks in the cooling system.
Coolant selection
Only use “Toyota Super Long Life Coolant” or similar high quality ethylene
glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant
with long-life hybrid organic acid technology.
“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50%
deionized water. (Enabled: -35C [-31F])
For more details about engine coolant, contact any authorized Toyota dealer
or repairer, or another duly qualified and equipped professional.
CAUTION
When the engine is hot
Do not remove the coolant reservoir cap.
The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing serious injuries, such as burns.
NOTICE
When adding engine coolant
Coolant is neither plain water nor straight antifreeze. The correct mixture of
water and antifreeze must be used to provide proper lubrication, corrosion
protection and cooling. Be sure to read the antifreeze or coolant label.
If you spill coolant
Be sure to wash it off with water to prevent damage to parts or paint.

If a large amount of coolant leaks,
immediately contact any autho-

Add coolant if necessary.
Water can be used in an emer-
gency if coolant is unavailable.
Start the engine and turn the air conditioning system on to
check that the radiator cooling fan operates and to check for
coolant leaks from the radiator or hoses.
The fan operates when the air conditioning system is turned on
immediately after a cold start. Confirm that the fan is operating by
checking the fan sound and air flow. If it is difficult to check these,
turn the air conditioning system on and off repeatedly.
(The fan may not operate in freezing temperatures.)
