2007 YAMAHA FZ6 S engine overheat

INSTRUMENT AND CONTROL FUNCTIONS
3-8
3Fuel meter
With the key in the “ON” position, the
fuel meter indicates the amount of fuel
in the fuel tank. When the key is turned
to “ON”, all of the display segments of
the fuel meter will appear one after the
other and then disappear in order to
test the electrical circuit. The display
segments of the fuel meter disappear
towards “E” (Empty) as the fuel level
decreases. When only one segment is
left near “E” (Empty), refuel as soon as
possible.
NOTE:This fuel meter is equipped with a self-
diagnosis system. If the electrical circuit
is defective, the following cycle will berepeated until the malfunction is cor-
rected: the display segments, except
the “F” (Full) and “E” (Empty) seg-
ments, will flash eight times and then
go off for 3 seconds. If this occurs, have
a Yamaha dealer check the electrical
circuit.
Coolant temperature meter
With the key in the “ON” position, the
coolant temperature meter indicates
the temperature of the coolant. When
the key is turned to “ON”, all of the dis-
play segments of the coolant tempera-
ture meter will appear one after the
other and then disappear in order to
test the electrical circuit. The coolanttemperature varies with changes in the
weather and engine load. If the top seg-
ment flashes, stop the vehicle and let
the engine cool. (See page 6-37.)
NOTE:This coolant temperature meter is
equipped with a self-diagnosis system.
If the electrical circuit is defective, the
following cycle will be repeated until the
malfunction is corrected: the display
segments, except the “H” (High) and “L”
(Low) segments, will flash eight times
and then go off for 3 seconds. If this oc-
curs, have a Yamaha dealer check theelectrical circuit.CAUTION:
ECA10020
Do not operate the engine if it isoverheated.

This model is equipped with a self-diag-
nosis device for various electrical cir-
cuits.

OPERATION AND IMPORTANT RIDING POINTS

EAU16810
Tips for reducing fuel con-
sumption Fuel consumption depends largely on
your riding style. Consider the following
tips to reduce fuel consumption:

Shift up swiftly, and avoid high en-
gine speeds during acceleration.


Do not rev the engine while shifting
down, and avoid high engine
speeds with no load on the engine.


Turn the engine off instead of let-
ting it idle for an extended length of
time (e.g., in traffic jams, at traffic
lights or at railroad crossings).
EAU16841
Engine break-in There is never a more important period
in the life of your engine than the period
between 0 and 1600 km (1000 mi). For
this reason, you should read the follow-
ing material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1600 km (1000 mi). The various parts in
the engine wear and polish themselves
to the correct operating clearances.
During this period, prolonged full-throt-
tle operation or any condition that might
result in engine overheating must be
avoided.
EAU17091
0–1000 km (0–600 mi)
Avoid prolonged operation above 7000
r/min.
1000–1600 km (600–1000 mi)
Avoid prolonged operation above 8400
r/min.
CAUTION:
ECA10301
After 1000 km (600 mi) of operation,
the engine oil must be changed and
the oil filter cartridge or element re-placed.
1600 km (1000 mi) and beyond
The vehicle can now be operated nor-
mally.CAUTION:
ECA10310


Keep the engine speed out of
the tachometer red zone.


If any engine trouble should oc-
cur during the engine break-in
period, immediately have a
Yamaha dealer check the vehi-cle.

6 4. Add coolant or distilled water to
raise the coolant to the maximum
level mark, install the coolant res-
ervoir cap.
CAUTION:
ECA10471


If coolant is not available, use
distilled water or soft tap water
instead. Do not use hard water
or salt water since it is harmful
to the engine.


If water has been used instead
of coolant, replace it with cool-
ant as soon as possible, other-wise the cooling system will not
be protected against frost and
corrosion.


If water has been added to the
coolant, have a Yamaha dealer
check the antifreeze content of
the coolant as soon as possible,
otherwise the effectiveness ofthe coolant will be reduced.WARNING
EWA10380
Never attempt to remove the radiatorcap when the engine is hot.NOTE:

The radiator fan is automatically
switched on or off according to the
coolant temperature in the radia-
tor.


If the engine overheats, see page6-37 for further instructions.
EAU40133
To change the coolant
1. Place the vehicle on the center-
stand and let the engine cool if
necessary.
2. Remove panel A. (See page 6-6.)3. Place a container under the engine
to collect the used coolant.
4. Remove the radiator cap retaining
bolt, radiator cap retainer and radi-
ator cap.
WARNING
EWA10380
Never attempt to remove the radiatorcap when the engine is hot.
5. Remove the coolant reservoir cap.

6 Engine overheating
WARNING
EWA10400


Do not remove the radiator cap when the engine and radiator are hot. Scalding hot fluid and steam may be
blown out under pressure, which could cause serious injury. Be sure to wait until the engine has cooled.


After removing the radiator cap retaining bolt, place a thick rag, like a towel, over the radiator cap, and then
slowly rotate the cap counterclockwise to the detent to allow any residual pressure to escape. When the hissingsound has stopped, press down on the cap while turning it counterclockwise, and then remove the cap.
NOTE:If coolant is not available, tap water can be temporarily used instead, provided that it is changed to the recommended coolantas soon as possible.
Wait until the
engine has cooled.
Check the coolant level in the
reservoir and radiator.
The coolant level
is OK.The coolant level is low.
Check the cooling system
for leakage.
Have a Yamaha dealer checkand repair the cooling system.Add coolant. (See NOTE.)
Start the engine. If the engine overheats again,
have a
Yamaha dealer check
and repair the cooling system.
There is
leakage.
There is
no leakage.
