Engine coolant
The coolant level is satisfactory if it is between the upper and lower
lines on the reservoir when the engine is cold.
Reservoir cap
Upper line
Lower line
If the level is on or below the
lower line, add coolant up to the
upper line. (P. 584)
Coolant selection
Only use “Toyota Super Long Life Coolant” or a 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. (Minimum temperature: -35C [-31F])
For more details about engine coolant, contact any authorized Toyota dealer
or repairer, or another duly qualified and equipped professional.
If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine coolant reservoir caps, 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.

Maintenance and care
HILUX_EE (OM0K132E)
CAUTION
When the engine is hot
Do not remove the engine 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 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 it from damaging parts or paint.

If your vehicle overheats
If your engine overheats:
Stop the vehicle in a safe place and turn off the air condi-
tioning system.
Check to see if steam is coming out from under the hood.
If you see steam:
Stop the engine. Carefully lift the hood after the steam sub-
sides and then restart the engine.
If you do not see steam:
Leave the engine running and carefully lift the hood.
Check to see if the cooling fan is operating.
If the fan is operating:
Wait until the temperature of the engine (shown on the
instrument panel) begins to fall and then stop the engine.
If the fan is not operating:
Stop the engine immediately and call any authorized Toyota
dealer or repairer, or another duly qualified and equipped
professional.
After the engine has cooled
down sufficiently, check the
engine coolant level and
inspect the radiator core (radi-
ator) for any leaks.

Overheating
If you observe the following, your vehicle may be overheating:
The engine coolant temperature gauge enters the red zone or a loss of
power is experienced.
Steam comes out from under the hood.
Add engine coolant if neces-
sary.
Water can be used in an emer-
gency if engine coolant is
unavailable. (P. 606)

CAUTION
To prevent an accident or injury when inspecting under the hood of
your vehicle
If steam is seen coming from under the hood, do not open the hood until
the steam has subsided. The engine compartment may be very hot, caus-
ing serious injuries such as burns.
Keep hands and clothing away from the fans and drive belt while the
engine is running.
Do not loosen the coolant reservoir cap while the engine and radiator are
hot.
Serious injury, such as burns, may result from hot coolant and steam
released under pressure.
NOTICE
When adding engine coolant
Wait until the engine has cooled down before adding engine coolant.
When adding coolant, do so slowly. Adding cool coolant to a hot engine too
quickly can cause damage to the engine.
