Engine shield
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.
If the level is at the MIN mark, add oil immediately.

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.

Removing Vehicle from Storage
When your vehicle is ready to come out of storage, do the following:
•Wash your vehicle to remove any dirt or grease film build-up on
window surfaces.
•Check windshield wipers for any deterioration.
•Check under the hood for any foreign material that may have collected
during storage (mice/squirrel nests).
•Check the exhaust for any foreign material that may have collected
during storage.
•Check tire pressures and set tire inflation per the Tire Label.
•Check brake pedal operation. Drive the vehicle 15 feet (4.5 meters)
back and forth to remove rust build-up.
•Check fluid levels (including coolant, oil and gas) to make sure there
are no leaks and fluids are at recommended levels.
•If the battery was removed, clean the battery cable ends and inspect.
Contact your authorized dealer if you have any concerns or issues.

1Ford recommends using Motorcraft (Ford) DOT 4 Low Viscosity High Performance Brake Fluid or
equivalent meeting WSS-M6C65-A2. Use of any fluid other than the recommended fluid may cause
degraded brake performance and not meet the Ford performance standards. Keep brake fluid clean
and dry. Contamination with dirt, water, petroleum products or other materials may result in brake
system damage and possible failure.2Approximate dry fill capacity. Actual amount may vary during fluid changes.3Automatic transmissions that require MERCON LV should only use MERCON LV fluid. Refer to
scheduled maintenance informationto determine the correct service interval. Use of any fluid other
than the recommended fluid may cause transmission damage.4See your authorized dealer for fluid level checking or filling.5Your engine has been designed to use Motorcraft engine oils or equivalent oils that meet Ford
specifications. It is also acceptable to use an engine oil of recommended viscosity grade that meets
API SN requirements and displays the API Certification Mark for gasoline engines.6Do not use supplemental engine oil additives in your engine. They are unnecessary and could lead to
engine damage that is not covered by your Ford warranty.

Oils, Fluids and Flushing
In many cases, fluid discoloration is a normal operating characteristic
and, by itself, does not necessarily indicate a concern or that the fluid
needs to be changed. However, discolored fluids that also show signs of
overheating and foreign material contamination should be inspected
immediately by a qualified expert, such as the factory-trained technicians
at your dealership. Your vehicle’s oils and fluids should be changed at the
specified intervals or in conjunction with a repair. Flushing is a viable
way to change fluid for many vehicle sub-systems during scheduled
maintenance. It is critical that systems are flushed only with new fluid
that is the same as that required to fill and operate the system, or using
a Ford-approved flushing chemical.
Owner Checks and Services
Certain basic maintenance checks and inspections should be performed
every month or at six month intervals.
Check every month
Engine oil level.
Function of all interior and exterior lights.
Tires (including spare) for wear and proper pressure.
Windshield washer fluid level.
Check every six months
Battery connections. Clean if necessary.
