Coolant - Yamaha WR25RB Owner's Manual

PERIODIC MAINTENANCE AND ADJUSTMENT

Coolant

The coolant level should be checked
1
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
2
and lubrication chart.
3
To check the coolant level
1. Place the vehicle on a level sur-
4
face and hold it in an upright posi-
tion.

TIP

The coolant level must be checked
6
on a cold engine since the level
varies with engine temperature.

Make sure that the vehicle is posi-
7
tioned straight up when checking
the coolant level. A slight tilt to the
8
side can result in a false reading.
2. Check the coolant level in the cool-
9
ant reservoir.
TIP
The coolant should be between the
minimum and maximum level marks.

minimum level mark, remove pan-
el C (See page 7-9.), remove the
coolant reservoir cap, add coolant
to the maximum level mark, and
then install the reservoir cap and
the panel. WARNING! Remove
only the coolant reservoir cap.
Never attempt to remove the ra-
diator cap when the engine is

[EWA15161]
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
7-16
of coolant, replace it with cool-
ant as soon as possible, other-
1
wise the cooling system will not
be protected against frost and
corrosion. If water has been
added to the coolant, have a
2
Yamaha dealer check the anti-
freeze content of the coolant as
soon as possible, otherwise the
effectiveness of the coolant will
be reduced.
