EVU00410Engine oil
Make sure the engine oil is at the specified
level. Add oil as necessary. (See pages 8-10–
8-15.)NOTICE●
In order to prevent clutch slippage
(since the engine oil also lubricates
the clutch), do not mix any chemical
additives with oil. Do not use oils with
a diesel specification of “CD” or oils
of a higher quality than specified. In
addition, do not use oils labeled “EN-
ERGY CONSERVING II” or higher.
●
Make sure that no foreign material en-
ters the crankcase.
EVU00420Coolant
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 8-22–8-23 for details.)NOTICEHard water or salt water is harmful to the
engine. You may use soft water if you can-
not get distilled water.
Recommended engine oil type and
quantity:See pages 10-1–10-2.
Coolant reservoir capacity
(up to the maximum level mark):0.32 L (0.34 US qt, 0.28 Imp.qt)
