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. SeeCapacities and Specificationsfor
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
The concentration and level of engine coolant should be checked at the
intervals listed inscheduled maintenance information.
The coolant concentration should be maintained 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
dealer. Ford does not recommend the use of hydrometers or coolant test
strips for measuring coolant concentrations.
Note:Make sure that the level is between the MIN and MAX marks on
the coolant reservoir.
