The coolant level is satisfactory if it
is between the “F” and “L” lines on
the reservoir when the engine is
cold.
Reservoir cap
“F” line
“L” line
If the level is on or below the “L” line,
add coolant up to the “F” line. ( →P.405)
■Coolant selection
Only use “Toyota Super Long Life Cool-
ant” 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 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 caps, 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.
Check the radiator, condenser clear
away any foreign objects. If either
of the above parts is extremely dirty
or you are not sure of their condi-
tion, have your vehicle inspected by
any authorized Toyota retailer or
Toyota authorized repairer, or any
reliable repairer.
Checking the coolant
WARNING
■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 mix- ture 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.

7-2. Steps to take in an emergency
When trouble arises
M15A-FKS engine
6 Start the engine and turn the air
conditioning system on to check
that the radiator cooling fan
operate and to check for coolant
leaks from the radiator or hoses.
The fan operate when the air condition- ing 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.)
7 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
any 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 (espe-cially a tie, a scarf or a muffler) away from the fan and belts. Failure
to do so may cause the hands or clothing to be caught, resulting in serious injury.
●Do not loosen the coolant reservoir caps while the engine and radiator
are hot. High temperature 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.
