Coolant drain bolt:
11 Nm (1.1 m·kgf, 8.0 ft·lbf)
12. Pour the specified amount of rec-
ommended coolant into the radia-
tor and reservoir.
Antifreeze/water mixture ratio:
1:1
Recommended antifreeze:
High-quality ethylene glycol anti-
freeze containing corrosion inhibitors
for aluminum engines
Coolant quantity:
Radiator capacity (including all
routes):
1.00 L (1.06 US qt) (0.88 Imp.qt)
Coolant reservoir capacity (up to the
maximum level mark):
0.25 L (0.26 US qt) (0.22 Imp.qt)
PERIODIC MAINTENANCE AND MINOR REPAIR
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.
13. Install the coolant reservoir cap.
14. Install the radiator cap and radiator
cap retainer by installing the
screw.
15. Start the engine, let it idle for sev-
eral minutes, and then turn it off.

ervoir. If necessary, remove the
coolant reservoir cap, add coolant

then install the cap.
17. Start the engine, and then check
the vehicle for coolant leakage. If
coolant is leaking, have a Yamaha
dealer check the cooling system.
