Only use oils certified for gasoline engines
by the American Petroleum Institute (API).
An oil with this trademark symbol
conforms to the current engine and
emission system protection standards and
fuel economy requirements of the
International Lubricants Specification
Advisory Council (ILSAC), comprised of
U.S. and Japanese automobile
manufacturers.
1.
Check the engine oil level.
2. If the engine oil level is not within the
normal range, add engine oil that
meets Ford specifications. See
Capacities and Specifications
(page
296).
3. Remove the engine oil filler cap and
use a funnel to pour the engine oil into
the opening.
4. Recheck the engine oil level. Make sure
the oil level is not above the normal
operating range on the engine oil level
dipstick.
5. Install the engine oil level dipstick and
ensure it is fully seated.
6. Fully install the engine oil filler cap by
turning the filler cap clockwise until
three clicks are heard or until the cap
is fully seated.
ENGINE COOLANT CHECK
WARNINGS
Do not add engine coolant when the
engine is hot. Steam and scalding
liquids released from a hot cooling
system can burn you badly. Also, spilling
coolant on hot engine parts can burn you.
Do not put engine coolant in the
windshield washer fluid container. If
sprayed on the windshield, engine
coolant could make it difficult to see
through the windshield.
WARNINGS
To reduce the risk of personal injury,
make sure the engine is cool before
unscrewing the coolant pressure
relief cap. The cooling system is under
pressure. steam and hot liquid can come
out forcefully when you loosen the cap
slightly.
Do not add coolant further than the
MAX mark.
Checking the Engine Coolant
When the engine is cold, check the
concentration and level of the engine
coolant at the intervals listed in the
scheduled maintenance information. See
Scheduled Maintenance
(page 438).
Note:
Make sure that the coolant level is
between the MIN and MAX marks on the
coolant reservoir.
Note:
Coolant expands when it is hot. The
level may extend beyond the MAX mark.
Note:
If the level is at the MIN mark, below
the MIN mark, or empty, add coolant
immediately. See
Adding Engine Coolant
in this chapter.
Maintain coolant concentration within
48% to 50%, which equates to a freeze
point between -30°F (-34°C) and -34°F
(-37°C).
Note:
For best results, coolant
concentration should be tested with a
refractometer such as Rotunda tool
300-ROB75240 available from your
authorized dealer. Ford does not
recommend the use of hydrometers or
coolant test strips for measuring coolant
concentrations.
Note:
Automotive fluids are not
interchangeable. Do not use engine coolant,
antifreeze or windshield washer fluid outside
of its specified function and vehicle location.
