Engine temperature gauge
This gauge indicates the coolant tem-
perature when the main switch is on.
The engine operating temperature
will vary with changes in weather and
engine load. If the needle points to
the red zone or higher, stop your
motorcycle and let the engine cool.
(See page 6-10 for details.)

Be sure no foreign material
enters the crankcase.
6. Start the engine and warm up for
a few minutes. While warming
up, check for oil leakage. If oil
leakage is found, stop the engine
immediately and check for
cause.

EAU01621*Cooling system
1. Check the coolant level in the
reservoir tank when the engine is
cold as the coolant level will vary
with engine temperature. The
coolant level should be between
the minimum and maximum
marks on the tank.
2. If the coolant level is at or below
the minimum mark, fill with tap
water (soft water) to bring the
level up to the specified level.
Change the coolant every two
years.
3. If your motorcycle overheats, see
page 6-38 for details.

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. Open the radiator cap as follows. Wait until the
engine has cooled. Remove the radiator cap stopper by removing the screw. Place a thick rag like a towel over
the radiator cap and slowly rotate the cap counterclockwise to the detent. This procedure allows any residual
pressure to escape. When the hissing sound has stopped, press down on the cap while turning counterclock-
wise and remove it.
NOTE:
If it is difficult to get the recommended coolant, tap water can be temporarily used, provided that it is changed to the rec-
ommended coolant as soon as possible.
Level is OK.
Wait until the engine
has cooled.
Restart the engine. If the engine overheats again, ask a
Yamaha dealer to inspect and repair the cooling system. Check the coolant level in the
reservoir tank and/or radiator.
Add coolant (See NOTE.)
Level is low, check thecooling system for leakage.Leakage.No
leakage.Ask a Yamaha dealer to inspect
and repair the cooling system.
