Coolant
The coolant level should be checked
regularly. In addition, the coolant must
be changed at the intervals specified in
the periodic maintenance chart.
TIP
If genuine Yamaha coolant is not avail-
able, use an ethylene glycol antifreeze
containing corrosion inhibitors for alu-
minum engines and mix with distilled
water at a 1:1 ratio.

To check the coolant level
Since the coolant level varies with en-
gine temperature, check when the en-
gine is cold.
1. Park the vehicle on a level surface.
2. With the vehicle in an upright posi-
tion, look at the coolant level in the
reservoir.
3. If the coolant is at or below the mi-
nimum level mark, remove the
coolant reservoir cap.
WARNING!
Remove only the coolant reser-
voir cap. Never attempt to re-
move the ra
d
iator cap when the
en
g
ine is hot.
