ENGINE OIL CHECK
Diesel Engine
See your engine operator’s manual for information on checking and
adding engine oil as well as engine oil specifications, capacities and
required maintenance.
Gasoline Engine
Checking the Engine Oil
1. Make sure your vehicle is on level ground.
2. Turn the engine off and wait 15 minutes for the oil to drain into the
oil pan.
3. Set the parking brake and latch the gearshift in positionP.
4. Open the hood. Protect yourself from engine heat.
5. Locate and carefully remove the engine oil dipstick.
6. Wipe the dipstick clean. Insert the dipstick fully, and then remove it
again.
•If the oil level is between the lower and upper holes, the oil level
is acceptable. DO NOT ADD OIL.
•If the oil level is below the lower hole, add enough oil to raise the
level within the lower and upper holes.
•Oil levels above the upper hole may cause engine damage. Have
an authorized dealer remove some of the oil.
7. Put the dipstick back in completely.

Adding Engine Oil
Note:Do not remove the engine oil 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). 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 Specifications
for 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 dipstick.
4. Put the dipstick back in completely.
5. Fully install the oil filler cap by turning it clockwise until it clicks or
stops turning.
ENGINE COOLANT CHECK
Diesel Engine
See your engine operator’s manual for information on checking and
adding engine coolant.
Fan Clutches
WARNING:Stay clear of the fan and fan area while the engine is
running or possible personal injury may occur.
Your vehicle’s cooling system is equipped with a viscous fan clutch
which:
•Helps control cooling, increases performance, improves fuel economy
and reduces noise.
•Bimetallic spring sensors control. Do not tamper with these sensors
as this may change their calibration or keep the fan clutch from
operating at all.
