2018 YAMAHA YZF-R6 radiator

Instrument and control functions
4-6
4 When the vehicle is turned on, the light
will perform a circuit check (come on
for a few seconds and then go off).
If the warning light remains on after
confirming that the oil level is correct
(page 7-13), have a Yamaha dealer
check the vehicle.
TIP

Even if the oil level is sufficient, the
warning light may flicker when rid-
ing up or downhill, or during sud-
den acceleration or deceleration,
but this is not a malfunction.
 If a malfunction is detected, the oil
level warning light will flash re-
peatedly. Have a Yamaha dealer
check the vehicle.
EAU11369Fuel level warnin g lig ht “ ”
This warning light comes on when you
are low on fuel. When the fuel level
drops below approximately 3.4 L (0.90
US gal, 0.75 Imp.gal), the light will
come on to remind you to refuel as
soon as possible.
When the vehicle is turned on, the light
will perform a circuit check (come on
for a few seconds and then go off).
If the warning light does not come on
during the circuit check, or if the warn-
ing light remains on after refueling,
have a Yamaha dealer check the vehi-
cle.
TIP
If a malfunction is detected, the fuel
level warning light will flash repeatedly.
Have a Yamaha dealer check the vehi-
cle.
EAU72930Coolant temperature warnin g
li g ht “ ”
This warning light comes on if the en-
gine overheats. If this occurs, reduce
the load on the engine immediately. If
message “HI” flashes in the coolant
temperature display, stop the vehicle,
then stop the engine and let the engine
cool.
The electrical circuit of the warning
light can be checked by turning the key
to “ON”. The warning light should
come on for a few seconds, and then
go off.
If the warning light does not come on
initially when the key is turned to “ON”,
or if the warning light remains on, have
a Yamaha dealer check the electrical
circuit.
NOTICE
ECA10022
Do not continue to operate the en-
g ine if it is overheatin g.
TIP
 For radiator-fan-equipped vehi-
cles, the radiator fan(s) automati-
cally switch on or off according to
the coolant temperature in the ra-
diator.
 If the engine overheats, see page
7-41 for further instructions.
EAU73171Engine trou ble warnin g lig ht “ ”
This warning light comes on if a prob-
lem is detected in the engine or other
vehicle control system. If this occurs,
have a Yamaha dealer check the on-
board diagnostic system.

Coolant
The coolant level should be checked
regularly. In addition, the coolant must
be changed at the intervals specified in
the periodic maintenance chart.
TIP
If genuine Yamaha coolant is not avail-
able, use an ethylene glycol antifreeze
containing corrosion inhibitors for alu-
minum engines and mix with distilled
water at a 1:1 ratio.
EAU3908BTo check the coolant level
Since the coolant level varies with en-
gine temperature, check when the en-
gine is cold.
1. Park the vehicle on a level surface.
2. With the vehicle in an upright posi- tion, look at the coolant level in the
reservoir. 3. If the coolant is at or below the mi-
nimum level mark, remove panel B
to access the coolant reservoir.
(See page 7-7.)
4. Remove the coolant reservoir cap. WARNING! Remove only the
coolant reservoir cap. Never at-
tempt to remove the ra diator
cap when the en gine is hot.
[EWA15162]
5. Add coolant to the maximum level
mark. NOTICE: If coolant is not
availa ble, use distille d water or
soft tap water instea d. Do not
use har d water or salt water
since it is harmful to the en gine.
If water has been used instead
of coolant, replace it with cool-
ant as soon as possi ble, other-
wise the coolin g system will not
b e protecte d a gainst frost an d
corrosion. If water has b een
a dde d to the coolant, have a
Yamaha dealer check the anti-
freeze content of the coolant as
soon as possi ble, otherwise the
effectiveness of the coolant will
b e red uced.
[ECA10473]
6. Install the coolant reservoir cap.
7. Install the panel.
Recommen ded coolant:
YAMALUBE coolant
Coolant quantity: Coolant reservoir (max level mark):0.25 L (0.26 US qt, 0.22 Imp.qt)

Replacin g the fuses
The main fuse, the ABS motor fuse,
and fuse box 1 are located under the
rider seat. (See page 4-23.)
TIP
To access the ABS motor fuse, remove
the starter relay cover by pulling it up-
ward.
Fuse box 2 is located under panel A.
(See page 7-7.)
If a fuse is blown, replace it as follows.
1. Turn the key to “OFF” and turn off the electrical circuit in question.
2. Remove the blown fuse, and then install a new fuse of the specified
amperage. WARNING! Do not
use a fuse of a hi gher ampera ge
ratin g than recommen ded to
avoi d causin g extensive dam-
a g e to the electrical system an d
possi bly a fire.

WARNING
EWAT1041
Do not remove the ra diator cap when the en gine an d ra diator are hot.
Scal din g hot flui d an d steam may b e blown out un der pressure, which
coul d cause serious injury. Be sure to wait until the eng ine has cooled.
 Place a thick ra g, like a towel, over the ra diator cap, an d then slowly ro-
tate the cap counterclockwise to the detent to allow any resi dual pres-
sure to escape. When the hissin g soun d has stopped , press down on the
cap while turnin g it counterclockwise, an d then remove the cap.
TIP
If coolant is not available, tap water can be temporarily used instead, provided
that it is changed to the recommended coolant as soon as possible.
Wait until the engine
has cooled.
Check the coolant
level in the reservoir
and radiator.Add coolant.
(See TIP.)
The coolant level is
OK.
There is no leakage.
There is leakage.
The coolant level is
low.
Check the cooling
system for leakage.
Have a Yamaha
dealer check and
repair the cooling
system.
Start the engine. If the engine overheats again,
have a Yamaha dealer check and repair the cooling
system.
