acceptable, DO NOT ADD OIL.
• If the oil level is below the MIN mark, add enough oil to raise the level
within the MIN-MAX range.

• Oil levels above the MAX mark may cause engine damage. Some oil
must be removed from the engine by a service technician.
7. Put the indicator back in and ensure it is fully seated.
Adding engine oil
1. Check the engine oil. For instructions, refer to Checking the engine
oil in this chapter.
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 or the letter F in FULL 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 1/4 turn
until it stops.
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 Recommendations
2.3L & 3.0L Engines
Look for this certification
trademark.
Use SAE 5W-20 engine oil.
Only use oils“Certified For Gasoline Engines ”by the American
Petroleum Institute (API). To protect your engine ’s warranty use
Motorcraft SAE 5W-20 or an equivalent 5W-20 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, cleaners or other engine
treatments. They are unnecessary and could lead to engine damage that
is not covered by Ford warranty.
Change your engine oil according to the appropriate schedule listed in
the scheduled maintenance guide.

Use SAE 5W-30 engine oil.
Only use oils“Certified For Gasoline Engines ”by the American
Petroleum Institute (API). To protect your engine ’s warranty use
Motorcraft SAE 5W-30 or an equivalent 5W-30 oil meeting Ford
specification WSS-M2C205 –A.
Do not use supplemental engine oil additives, cleaners or other engine
treatments. They are unnecessary and could lead to engine damage that
is not covered by Ford warranty.
Change your engine oil 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.
BATTERY
Your vehicle is equipped with a
Motorcraft maintenance-free battery
which normally does not require
additional water during its life of
service.
However, for severe usage or in high temperature climates, check the
battery electrolyte level. Refer to the scheduled maintenance guide for
the service interval schedules.
Keep the electrolyte level in each cell up to the “level indicator ”.
Do not overfill the battery cells.

ENGINE COOLANT
Checking engine coolant
The concentration and level of engine coolant should be checked at the
mileage intervals listed in the scheduled maintenance guide. The coolant
concentration should be maintained at 50/50 coolant and distilled water,
which equates to a freeze point of -36°C (-34 °F). Coolant concentration
testing is possible with a hydrometer or antifreeze tester (such as the
Rotunda Battery and Antifreeze Tester, 014 –R1060). The level of coolant
should be maintained at the “cold full ”of “cold fill range ”level in the
coolant reservoir. If the level falls below, add coolant per the instructions
in the Adding Engine Coolant section.
Your vehicle was factory-filled with a 50/50 engine coolant and water
concentration. If the concentration of coolant falls below 40% or above
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.
