Maintenance and care
HILUX_OM_OM0K219E_(EE)
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. 482)
■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% deion-
ized 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.

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 stra ight 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.
■
Notice on coolant quality
Do not use improper coolant. If improper coolant is used, the engine cooling
system may be damaged.

If you think something is wrong
●Fluid leaks under the vehicle.
(Water dripping from the air conditioning after use is normal.)
● Flat-looking tires or uneven tire wear
● Engine coolant temperature gauge needle continually points higher
than normal.
● Changes in exhaust sound
● Excessive tire squeal when cornering
● Strange noises related to the suspension system
● Pinging or other noises related to the engine
● Engine missing, stumbling or running roughly
● Appreciable loss of power
● Vehicle pulls heavily to one side when braking
● Vehicle pulls heavily to one side when driving on a level road
● Loss of brake effectiveness, spongy feeling, pedal almost touches
the floor
If you notice any of the following symptoms, your vehicle proba-
bly needs adjustment or repair. Contact any authorized Toyota

HILUX_OM_OM0K219E_(EE)
If your vehicle overheats
Stop the vehicle in a safe place and turn off the air conditioning sys-
tem, and then stop the engine.
If you see steam:
Carefully lift the hood after the steam subsides.
If you do not see steam:
Carefully lift the hood.
After the engine has cooled down sufficiently, inspect the hoses and
radiator core (radiator) for any leaks.Radiator
Cooling fan
If a large amount of coolant
leaks, immediately contact any
authorized Toyota dealer or
repairer, or another duly quali-
fied and equipped professional.
The following may indicate that your vehicle is overheating.● The needle of the engine coolant temperature gauge ( →P. 100)
enters the red zone or a loss of engine power is experienced.
(For example, the vehicle speed does not increase.)
● Steam comes out from under the hood.

4847-2. Steps to take in an emergency
HILUX_OM_OM0K219E_(EE)
Start the engine to check that the radiator cooling fan operates and
to check for coolant leaks from the radiator or hoses.
If the fan is not operating:
Stop the engine immediately and contact any authorized Toyota
dealer or repairer, or another duly qualified and equipped profes-
sional.
If the fan is operating:
Have the vehicle inspected at the nearest authorized Toyota dealer
or repairer, or another duly qualified and equipped professional.
CAUTION
■When inspecting under the hood of your vehicle
Observe the following precautions.
Failure to do so may result in serious injury such as burns.
● 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.
● Keep hands and clothing (especially a tie, a scarf or a muffler) away from
the fans and belts. Failure to do so may cause the hands or clothing to be
caught, resulting in serious injury.
● Do not loosen the radiator cap or the coolant reservoir cap while the
engine and radiator are hot. High tem perature steam or coolant could
spray out.
NOTICE
■ When adding engine coolant
Add coolant slowly after the engine has cooled down sufficiently. Adding
cool coolant to a hot engine too quickly can cause damage to the engine.
■
To prevent damage to the cooling system
Observe the following precautions:
● Avoid contaminating the coolant with foreign matter (such as sand or dust
etc.).
● Do not use any coolant additive.
