Coolant
The coolant level should be checked
regularly. In addition, the coolant must
be changed at the intervals sp
ed 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.

Why Yamalube
YAMALUBE oil is a Genuine YAMAHA Part
born of the engineers’ passion and belief
that engine oil is an important liquid engine
component. We form teams of specialists in
the fields of mechanical engineering, chem-
istry, electronics and track testing, and have
them develop the engine together with the oil
it will use. Yamalube oils take full advantage
of the base oil's qualities and blend in the
ideal balance of additives to make sure the
final oil clears our performance standards.
Thus, Yamalube mineral, semisynthetic
and synthetic oils have their own distinct
characters and value. Yamaha's experience
gained over many years of research and
development into oil since he 1960's helps
make Yamalube the seal choice for your
Yamaha engine.
