reservoir when the engine is cold as the
coolant level will vary with engine temper-
ature. The coolant level should be
between the maximum and minimum
marks.

page 4-23 for seat removal and installa-
tion procedures.)
3. Open the coolant reservoir cover.
4. Remove the coolant reservoir cap, and
then add coolant or distilled water to raise
it to the specified level.
5. Install the coolant reservoir cap.
