drained, thoroughly flush the cool-
ing system with clean tap water.
PERIODIC MAINTENANCE AND MINOR REPAIR
7. Install the coolant drain bolt, and
then tighten it to the specified
torque.
NOTE:
Check the washer for damage and re-
place it if necessary.
Tightening torque:
Coolant drain bolt:
7 Nm (0.7 m·kgf, 5 ft·lbf)
8. Pour the recommended coolant
into the radiator until it is full.
Recommended antifreeze:
High-quality ethylene glycol anti-
freeze containing corrosion inhibitors
for aluminum engines
Antifreeze/water mixture ratio:
1:1
Coolant quantity:
Radiator capacity (including all
routes):
2.40 L (2.54 US qt) (2.11 Imp.qt)
Coolant reservoir capacity:
0.30 L (0.32 US qt) (0.26 Imp.qt)
6-16
CAUTION:
G
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.
G If water has been used instead
of coolant, replace it with cool-
ant as soon as possible, other-
wise the engine may not be
sufficiently cooled and the cool-
ing system will not be protected
against frost and corrosion.
G
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 of
the coolant will be reduced.
9. Install the radiator cap, start the
engine, let it idle for several min-
utes, and then turn it off.
10. Remove the radiator cap to check
the coolant level in the radiator. If
necessary, add sufficient coolant
