Coolant - Yamaha YZF-R6 Owner's Manual

Periodic maintenance and adjustment

Coolant

The coolant level should be checked
regularly. In addition, the coolant must
be changed at the intervals specified in
the periodic maintenance chart.
Recommended coolant:
YAMALUBE coolant
Coolant quantity:
Coolant reservoir (max level mark):
0.25 L (0.26 US qt, 0.22 Imp.qt)
Radiator (including all routes):
2.30 L (2.43 US qt, 2.02 Imp.qt)
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.

5. Add coolant to the maximum level

mark. NOTICE: 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. If water has been
added to the coolant, have a
Yamaha dealer check the anti-
freeze content of the coolant as
soon as possible, otherwise the
effectiveness of the coolant will
be reduced.
6. Install the coolant reservoir cap.
7. Install the panel.
