engine FORD EXPLORER 2010 4.G Owners Manual

If the service engine soonindicator remains on, have your vehicle
serviced at the first available opportunity. Although some malfunctions
detected by the OBD-II may not have symptoms that are apparent,
continued driving with the service engine soon
indicator on can
result in increased emissions, lower fuel economy, reduced engine and
transmission smoothness, and lead to more costly repairs.
Readiness for Inspection/Maintenance (I/M) testing
Some state/provincial and local governments may have
Inspection/Maintenance (I/M) programs to inspect the emission control
equipment on your vehicle. Failure to pass this inspection could prevent
you from getting a vehicle registration. Your vehicle may not pass the I/M
test if the service engine soon
indicator is on or not working
properly (bulb is burned out), or if the OBD-II system has determined
that some of the emission control systems have not been properly
checked. In this case, the vehicle is considered not ready for I/M testing.
If the service engine soon
indicator is on or the bulb does not
work, the vehicle may need to be serviced. Refer to the On board
diagnostics (OBD-II) description in this chapter.
If the vehicle’s engine or transmission has just been serviced, or the
battery has recently run down or been replaced, the OBD-II system may
indicate that the vehicle is not ready for I/M testing. To determine if the
vehicle is ready for I/M testing, turn the ignition key to the on position
for 15 seconds without cranking the engine. If the service engine
soon
indicator blinks eight times, it means that the vehicle is not
ready for I/M testing; if the service engine soon
indicator stays on
solid, it means that the vehicle is ready for I/M testing.
The OBD-II system is designed to check the emission control system
during normal driving. A complete check may take several days. If the
vehicle is not ready for I/M testing, the following driving cycle consisting
of mixed city and highway driving may be performed:
15 minutes of steady driving on an expressway/highway followed by
20 minutes of stop-and-go driving with at least four 30-second idle
periods.
Allow the vehicle to sit for at least eight hours without starting the
engine. Then, start the engine and complete the above driving cycle. The
engine must warm up to its normal operating temperature. Once started,
do not turn off the engine until the above driving cycle is complete. If
the vehicle is still not ready for I/M testing, the above driving cycle will
have to be repeated.

POWER STEERING FLUID
Check the power steering fluid. Refer toscheduled maintenance
information.
1. Start the engine and let it run
until it reaches normal operating
temperature (the engine coolant
temperature gauge indicator will be
near the center of the normal area
between H and C).
2. While the engine idles, turn the
steering wheel left and right several
times.
3. Turn the engine off.
4. Check the fluid level in the reservoir.
5. The fluid level should be between the MIN and MAX lines. Do not add
fluid if the level is in this range.
6. If the fluid is low, add fluid in small amounts, continuously checking
the level until it reaches the correct operating range. Be sure to put the
cap back on the reservoir. Refer toMaintenance product specifications
and capacitiesin this chapter for the proper fluid type.
BRAKE FLUID
The fluid level will drop slowly as
the brakes wear, and will rise when
the brake components are replaced.
Fluid levels between the MIN and
MAX lines are within the normal
operating range; there is no need to
add fluid. If the fluid levels are
outside of the normal operating
range, the performance of the
system could be compromised; seek
service from your authorized dealer
immediately.
TRANSMISSION FLUID
Checking automatic transmission fluid
The automatic transmission does not have an underhood transmission
fluid dipstick.

DRIVELINE UNIVERSAL JOINT, DRIVESHAFT AND SLIP YOKE
WARNING:Turn off the power running boards, if equipped,
before working under the vehicle, jacking or placing any object
under the vehicle. Never place your hand between the extended
running board and the vehicle. A moving running board may cause
injury.
If the original universal joints are replaced with universal joints equipped
with grease fittings, periodic lubrication will be necessary.
Note:Your vehicle’s driveshaft is balanced. If undercoating the vehicle,
protect the driveshaft, universal joints, and axle and transmission flanges
to prevent overspray of any undercoating material. If your vehicle has
four-wheel drive, your vehicle has two driveshafts, one connected to the
rear axle and one connected to the front axle.
AIR FILTER
Refer toscheduled maintenance informationfor the appropriate
intervals for changing the air filter element.
When changing the air filter element, use only the air filter element
listed. Refer toMotorcraft part numbersin this chapter.
WARNING:To reduce the risk of vehicle damage and/or
personal burn injuries do not start your engine with the air
cleaner removed and do not remove it while the engine is running.

Changing the air filter element
•4.0L Engine
•4.6L Engine
1. Release the clamps that secure the air filter housing cover.
2. Carefully separate the two halves of the air filter housing.
3. Remove the air filter element from the air filter housing.
4. Wipe the air filter housing and cover clean to remove any dirt or
debris and to ensure good sealing.
5. Install a new air filter element. Be careful not to crimp the filter
element edges between the air filter housing and cover. This could cause
filter damage and allow unfiltered air to enter the engine if not properly
seated.
6. Replace the air filter housing cover and secure the clamps.
Note:Failure to use the correct air filter element may result in severe
engine damage. The customer warranty may be void for any damage to
the engine if the correct air filter element is not used.
