Some vehicles may be equipped with an aero-shield under the engine.
This shield needs to be removed for service, including oil and filter
changes. It is secured with four quick release fasteners.

ENGINE OIL CHECK
Note:Check the level before starting the engine.
Note:Make sure that the level is between the MIN and MAX marks.
1. Make sure that your vehicle is on level ground.
2. Turn the engine off and wait 10 minutes for the oil to drain into the
oil pan.
3. Remove the dipstick and wipe it with a clean, lint-free cloth. Replace
the dipstick and remove it again to check the oil level.

Adding Engine Oil
Note:Do not remove 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. Remove the filler cap.
2. Add engine oil that meets Ford specifications. SeeCapacities and
Specificationsfor more information.
3. Wipe off any spilled oil.
4. Replace the filler cap. Turn it until you feel a strong resistance.
ENGINE COOLANT CHECK
Checking the Engine Coolant
The concentration and level of engine coolant should be checked at the
intervals listed inScheduled 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.
If the level is at the MIN mark, below the MIN mark, or empty, add
coolant immediately. SeeAdding Engine Coolantin this chapter.
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 Robinair Coolant and Battery Refractometer
75240. We do 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.

Engine
•The engine oil and filter should be changed prior to storage, as used
engine oil contains contaminates that may cause engine damage.
•Start the engine every 15 days. Run at fast idle with the climate
controls set to defrost until it reaches normal operating temperature.
•With your foot on the brake, shift through all the gears while the
engine is running.
Fuel system
•Fill the fuel tank with high-quality fuel until the first automatic shutoff
of the fuel pump nozzle.
Cooling system
•Protect against freezing temperatures.
•When removing vehicle from storage, check coolant fluid level.
Confirm there are no cooling system leaks, and fluid is at the
recommended level.
Battery
•Check and recharge as necessary. Keep connections clean.
•If storing your vehicle for more than 30 days without recharging the
battery, it may be advisable to disconnect the battery cables to ensure
battery charge is maintained for quick starting.
Note:If battery cables are disconnected, it will be necessary to reset
memory features.
Brakes
•Make sure brakes and parking brake are fully released.
Tires
•Maintain recommended air pressure.
Miscellaneous
•Make sure all linkages, cables, levers and pins under vehicle are
covered with grease to prevent rust.
•Move vehicles at least 25 feet (8 meters) every 15 days to lubricate
working parts and prevent corrosion.
