CHECKING THE ENGINE COOLANT
LEVEL
1Reservoir cap2Upper line3Lower line
Look at the see-through coolant reservoir when the
engine is cold. The coolant level is satisfactory if it is
between the Fº and Lº lines on the reservoir. If the level
is low, add the coolant. (For the coolant type, see Coolant
type selectionº described below.)
The coolant level in the reservoir will vary with engine
temperature. However, if the level is on or below the Lº line,
add coolant. Bring the level up to the Fº line.
