The coolant level is satisfactory if it is between the “F” and “L” lines on
the reservoir when the engine is cold.
If the level is on or below the “L” line, add coolant up to the “F” line.
( P. 645)
■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 retailer
or Toyota authorized repairer, or any reliable repairer.
■ If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine coolant reservoir cap, drain cock
and water pump. If you cannot find a leak, have any authorized Toyota retailer
or Toyota authorized repairer, or any reliable repairer test the cap and check
for leaks in the cooling system.

Maintenance and care
Check the radiator, condenser and intercooler and clear away any for-
eign objects. If any of the above parts is extremely dirty or you are not
sure of their condition, have your vehicle inspected by any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
WARNING
■ When the engine is hot
Do not remove the radiator cap or 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.
■ Notice on coolant quality
Do not use improper coolant. If improper coolant is used, the engine cooling
system may be damaged.
Radiator, condenser and intercooler (if equipped)
WARNING
■ When the engine is hot
Do not touch the radiator, condenser or intercooler as they may be hot and
cause serious injuries, such as burns.

6008-2. Steps to take in an emergency
HILUX_OM_OM0K375E_(EE)
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
retailer or Toyota authorized repairer, or any reliable repairer as
soon as possible.

When trouble arises
If your vehicle overheats
●The needle of the engine coolant temperature gauge (P. 132)
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.
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.

Cooling fan
If a large amount of coolant
leaks, immediately contact any
authorized Toyota retailer or
Toyota authorized repairer, or
any reliable repairer.
The following may indicate that your vehicle is overheating.

When trouble arises
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
retailer or Toyota authorized repairer, or any reliable repairer.
If the fan is operating:
Have the vehicle inspected at the nearest authorized Toyota retailer
or Toyota authorized repairer, or any reliable repairer.
WARNING
■ 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.
