Coolant; Final Gear Oil; Differential Gear Oil - Yamaha YSR45FX Owner's Manual

Coolant
Check the coolant level in the coolant reser-
voir when the engine is cold (the coolant level
will vary with engine temperature).
The coolant level is satisfactory if it is between
the minimum and maximum level marks on
the coolant reservoir. If the coolant level is at
or below the minimum level mark, add addi-
tional coolant to bring the level up to maxi-
mum level mark. If coolant is not available,
add distilled water. Change the coolant every
two years. (See pages 8-19-8-20 for details.)
NOTICE
Hard water or salt water is harmful to the
engine. You may use soft water if you can-
not get distilled water.
