Coolant - Yamaha YZF-R1 Owner's Manual

Coolant

The coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
To check the coolant level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion.
NOTE:
G
The coolant level must be checked
on a cold engine since the level
varies with engine temperature.
G
Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to the
side can result in a false reading.
2. Check the coolant level in the cool-
ant reservoir.
NOTE:
The coolant should be between the
minimum and maximum level marks.

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.
