2022 TOYOTA GR86 engine coolant

2906-2. Maintenance
request that a record of maintenance
be kept.
■Does your vehicle need repairs?
Be on the alert for changes in perfor- mance and sounds, and visual tip-offs
that indicate service is needed. Some
important clues are:
●Engine missing, stumbling or pinging
●Appreciable loss of power
●Strange engine noises
●A fluid leak under the vehicle (How-
ever, water dripping from the air con- ditioning system after use is normal.)
●Change in exhaust sound (This may indicate a dangerous carbon monox-
ide leak. Drive with the windows open
and have the exhaust system checked immediately.)
●Flat-looking tires, excessive tire squeal when cornering, uneven tire
wear
●Vehicle pulls to one side when driven
straight on a level road
●Strange noises related to suspension
movement
●Loss of brake effectiveness, spongy
feeling brake pedal or clutch pedal
(vehicles with a manual transmission),
pedal almost touches the floor, vehicle pulls to one side when braking
●Engine coolant temperature continu-ally higher than normal ( P. 8 8 )
If you notice any of these clues, take
your vehicle to any authorized Toyota retailer or Toyota authorized repairer, or
any reliable repairer as soon as possi-
ble. Your vehicle may need adjustment or repair.

WA R N I N G
The engine compartment contains
many mechanisms and fluids that may move suddenly, become hot, or
become electrically energized. To
avoid death or serious injury, observe the following precautions.
ItemsParts and tools

WA R N I N G
■When working on the engine
compartment
●Keep hands, clothing and tools away from the moving fans and
engine drive belt.
●Be careful not to touch the engine,
radiator, exhaust manifold, etc. right
after driving as they may be hot. Oil
and other fluids may also be hot.
●Do not leave anything that may
burn easily, such as paper and rags, in the engine compartment.
●Do not smoke, cause sparks or expose an open flame to fuel or the
battery. Fuel and battery fumes are
flammable.
●Be extremely cautious when work-
ing on the battery. It contains poi- sonous and corrosive sulfuric acid.
●Take care because brake fluid can harm your hands or eyes and dam-
age painted surfaces. If fluid gets
on your hands or in your eyes, flush the affected area with clean water
immediately.
If you still experience discomfort, con- sult a doctor.
■When working near the electric cooling fans or radiator grille
Be sure the engine switch is off.
With the engine switch in ON, the electric cooling fans may automati-
cally start to run if the air conditioning
is on and/or the coolant temperature is high. (P.298)
■Safety glasses
Wear safety glasses to prevent flying
or falling material, fluid spray, etc.
from getting in your eyes.
NOTICE
■If you remove the air cleaner fil-
ter
Driving with the air cleaner filter removed may cause excessive
engine wear due to dirt in the air.
■If the fluid level is low or high
It is normal for the brake fluid level to
go down slightly as the brake pads
wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refill-
ing, it may indicate a serious problem.

Maintenance and care
refilled in between oil maintenance inter-
vals.
●When the engine is new, for example
directly after purchasing the vehicle or after replacing the engine
●If low quality oil or oil of an inappropri-ate viscosity is used
●When driving at high engine speeds or with a heavy load, or when driving
while accelerating or decelerating fre-
quently
●When leaving the engine idling for a
long time, or when driving frequently through heavy traffic
The coolant level is satisfactory if it
is between the “FULL” and “LOW”
lines on the reservoir when the
engine is cold.
■Engine coolant reservoir
Reservoir cap
“FULL” line
“LOW” line
If the level is on or below the “LOW”
line, add coolant up to the “FULL” line.
( P.362)
■Coolant selection
Only use “TOYOTA Genuine 50/50
Pre-mixed Super Long Life Coolant BLUE” 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.
WA R N I N G
■Used engine oil
●Used engine oil contains poten-
tially harmful contaminants which may cause skin disorders such as
inflammation and skin cancer, so
care should be taken to avoid pro- longed and repeated contact. To
remove used engine oil from your
skin, wash thoro ughly with soap and water.
●Dispose of used oil and filters only in a safe and acceptable manner.
Do not dispose of used oil and fil-
ters in household trash, in sewers or onto the ground. Call any author-
ized Toyota dealer or repairer, or
another duly qualified and equipped professional, service station or auto
parts store for information concern-
ing recycling or disposal.
●Do not leave used engine oil within
the reach of children.
NOTICE
■To prevent serious engine dam-
age
Check the oil level on a regular basis.
■When replacing the engine oil
●Be careful not to spill engine oil on
the vehicle components.
●Avoid overfilling, or the engine
could be damaged.
●Check the oil level on the dipstick
every time you refill the vehicle.
●Be sure the engine oil filler cap is
properly tightened.

2986-3. Do-it-yourself maintenance
“TOYOTA Genuine 50/50 Pre-mixed
Super Long Life Coolant BLUE” is a mix- ture 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 your Toyota dealer test the cap and check for
leaks in the cooling system.
Check the radiator and condenser
and clear away any foreign objects.
If either 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.
Check the battery as follows.
■Battery exterior
Make sure that the battery termi-
nals are not corroded and that there
are no loose connections, cracks,
or loose clamps.
Hold-down clamp
Terminals
■Checking battery fluid
Check that the level is between the
“UPPER LEVEL” and “LOWER
LEVEL” lines.
WA R N I N G
■When the engine is hot
Do not remove the engine coolant reservoir cap. ( P.364)
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.
Checking the radiator and
condenser

■When the engine is hot
Do not touch the radiator or con-
denser as they may be hot and cause serious injuries, such as burns.
