Adding Engine Oil
Note:
Do not remove the engine oil level dipstick or the filler cap when
the engine is running.
Note:
Do not add engine oil further than the MAX mark. Oil levels above
the MAX mark may cause engine damage.
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
for
more information. Remove the engine oil filler cap and use a funnel to
pour the engine oil into the opening.
3. Recheck the engine oil level. Make sure the oil level is not above the
normal operating range on the engine oil level dipstick.
4. Install the dipstick and ensure it is fully seated.
5. 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
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.
Note:
Make sure that the 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.
The coolant concentration should be maintained within 48% to 50%, which
equates to a freeze point between -30 degrees Fahrenheit (-34 degrees
Centigrade) and -34 degrees Fahrenheit (-37 degrees Centigrade).
