Checking Oil Level
To assure proper engine lubrication, the en-
gine oil must be maintained at the correct
level. Check the oil level at regular intervals,
such as every fuel stop. The best time to
check the engine oil level is about five min-
utes after a fully warmed engine is shut off.
Do not check oil level before starting the
engine after it has sat overnight. Checking
engine oil level when the engine is cold will
give you an incorrect reading.
Checking the oil while the vehicle is on level
ground and only when the engine is hot, will
improve the accuracy of the oil level read-
ings. Maintain the oil level between the range
markings on the dipstick. The range markings
will consist of a crosshatch zone which de-
picts the MIN at the low end of the range and
MAX at the high end of the range. Adding
1 quart (1 liter) of oil when the reading is at
the low end of the indicated range will result
in the oil level at the full end of the indicator
range.
CAUTION!
Do not overfill the engine. Overfilling the
engine will cause oil aeration, which can
lead to loss of oil pressure and an increase
in oil temperature. This could damage
your engine. Also, be sure the oil fill cap is
replaced and tightened after adding oil.
Cooling System
WARNING!
• When working near the radiator cooling
fan, disconnect the fan motor lead or
turn the ignition switch to the OFF posi-
tion. The fan is temperature controlled
and can start at any time the ignition
switch is in the ON position.
• You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam
coming from under the hood, do not open
the hood until the radiator has had time to
cool. Never try to open a cooling system
pressure cap when the radiator is hot.
Coolant Checks
Check engine coolant (antifreeze) protection
every 12 months (before the onset of freezing
weather, where applicable). If the engine
coolant (antifreeze) is dirty or rusty in appear-
ance, the system should be drained, flushed,
and refilled with fresh engine coolant (anti-
freeze). Check the front of the A/C condenser
for any accumulation of bugs, leaves, etc. If
dirty, clean by gently spraying water from a
garden hose vertically down the face of the
condenser.
Check the coolant recovery bottle tubing for
brittle rubber, cracking, tears, cuts, and
tightness of the connection at the bottle and
radiator. Inspect the entire system for leaks.
Adding Washer Fluid
The washer fluid reservoir is located in the
engine compartment, and the fluid level
should be checked at regular intervals. Fill
the reservoir with windshield washer solvent
only (not radiator antifreeze).
When refilling the washer fluid reservoir, take
some washer fluid and apply it to a cloth or
towel and wipe clean the wiper blades, this
