Check the coolant level in the coolant reservoir 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 distilled water to bring the level up to
maximum level mark. Change the coolant every two years. (See pages 8-17-8-18 for
details.)
CAUTION:
Hard water or salt water is harmful to the engine. You may use soft water if you can not
get distilled water.
