2003 FORD EXPEDITION check oil

2. If the engine oil level is not within the normal range, add only certified
engine oil of the recommended viscosity. 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
MAX mark on the engine oil level indicator (dipstick).
4. Install the indicator and ensure it is fully seated.
5. Fully install the engine oil filler cap by turning the filler cap clockwise
1/4 of a turn until the cap is fully seated.
To avoid possible oil loss, DO NOT operate the vehicle with the
engine oil level indicator and/or the engine oil filler cap removed.
Engine oil and filter recommendations
Look for this certification
trademark.
SAE 5W-20 engine oil is recommended.
Only use oils“Certified For Gasoline Engines”by the American
Petroleum Institute (API). Use Motorcraft or an equivalent oil meeting
Ford specification WSS-M2C153–H.SAE 5W-20 oil provides optimum
fuel economy and durability performance meeting all
requirements for your vehicle’s engine.
Do not use supplemental engine oil additives, oil treatments or engine
treatments. They are unnecessary and could, under certain conditions,
lead to engine damage which is not covered by your warranty.
Change your engine oil and filter according to the appropriate schedule
listed in the scheduled maintenance guide.
Ford production and aftermarket (Motorcraft) oil filters are designed for
added engine protection and long life. If a replacement oil filter is used
that does not meet Ford material and design specifications, start-up
engine noises or knock may be experienced.
It is recommended you use the appropriate Motorcraft oil filter (or
another brand meeting Ford specifications) for your engine application.

60%, the engine parts could become damaged or not work properly.A
50–50 mixture of coolant and water provides the following:
•Freeze protection down to -36°C (-34°F).
•Boiling protection up to 129°C (265°F).
•Protection against rust and other forms of corrosion.
•Enables calibrated gauges to work properly.
When the engine is cold, check the
level of the engine coolant in the
reservoir.
•The engine coolant should be at the“cold fill level”or within the“cold
fill range”as listed on the engine coolant reservoir (depending upon
application).
•Refer to the Scheduled Maintenance Guide for service interval
schedules.
•Be sure to read and understandPrecautions when servicing your
vehiclein this chapter.
If the engine coolant has not been checked at the recommended interval,
the engine coolant reservoir may become low or empty. If the reservoir is
low or empty, add engine coolant to the reservoir. Refer toAdding
engine coolantin this chapter.
Note:Automotive fluids are not interchangeable; do not use engine
coolant, antifreeze or windshield washer fluid outside of its specified
function and vehicle location.
Maintenance and Specifications

•Revving the engine before turning it off may reduce fuel economy.
•Using the air conditioner or defroster may reduce fuel economy.
•You may want to turn off the speed control in hilly terrain if
unnecessary shifting between third and fourth gear occurs.
Unnecessary shifting of this type could result in reduced fuel
economy.
•Warming up a vehicle on cold mornings is not required and may
reduce fuel economy.
•Resting your foot on the brake pedal while driving may reduce fuel
economy.
•Combine errands and minimize stop-and-go driving.
Maintenance
•Keep tires properly inflated and use only recommended size.
•Operating a vehicle with the wheels out of alignment will reduce fuel
economy.
•Use recommended engine oil. Refer toLubricant specificationsin
this chapter.
•Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found in your vehicle scheduled maintenance guide.
Conditions
•Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
•Carrying unnecessary weight may reduce fuel economy (as much as
0.4 km/L [1 mpg] is lost for every 180 kg [400 lb] of weight carried).
•Adding certain accessories to your vehicle (for example bug
deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
•Using fuel blended with alcohol may lower fuel economy.
•Fuel economy may decrease with lower temperatures during the first
12–16 km (8–10 miles) of driving.
•Driving on flat terrain offers improved fuel economy as compared to
driving on hilly terrain.
•Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the gas pedal.
Maintenance and Specifications

1Ensure the correct automatic transmission fluid is used. Transmission
fluid requirements are indicated on the dipstick or on the dipstick
handle. Check the container to verify the fluid being added is of the
correct type. Refer to your scheduled maintenance guide to determine
the correct service interval.
Some transmission fluids may be labeled as dual usage, such as
MERCONand MERCONV. These dual usage fluids are not to be used
in an automatic transmission that requires use of the MERCONtype
fluid. However, these dual usage fluids may be used in transmissions that
require the MERCONV type fluid.
MERCONand MERCONV type fluids are not interchangeable.
DO NOT mix MERCONand MERCONV. Use of a transmission
fluid that indicates dual usage (MERCONand MERCONV) in
an automatic transmission application requiring MERCONmay
cause transmission damage. Use of any fluid other than the
recommended fluid may cause transmission damage.
