WINDSHIELD WIPER/WASHER CONTROLS
Rotate the windshield wiper control
to the desired interval, low or high
speed position.
The bars of varying length are for
intermittent wipers. When in this
position rotate the control upward
for fast intervals and downward for
slow intervals.
Push the end of the stalk to activate
washer. Push and hold for a longer
wash cycle.
Windshield wiper/washer features
The exterior lamps will illuminate after 10–20 second delay when the
ignition is ON and the windshield wiper control is in the LO or HI
position.
The lights will remain on for 30 seconds after the wipers are turned off.
Maintenance and care of windshield wiper blades
Check the wiper blades for wear at least twice a year or when they seem
less effective. Substances such as tree sap, road salt, oil film and some
hot wax treatments used by commercial car washes reduce the
effectiveness of wiper blades.
Operation of the wipers on dry glass for long periods of time may cause
deterioration of the wiper blades. Always use washer fluid when using
the wipers to remove salt or dirt from a dry windshield. Avoid using the
blades to remove frost or ice from the windshield. If the wiper blades are
frozen to the windshield, loosen the wiper blades before operating the
wipers to prevent damage to the wiper system.
It the windshield is not clear after using the windshield washer wiper
system, or if the wiper blades chatter, streak or smear when operating, it
is possible that wax, road salt or oil film may be on the windshield or the
wiper blades. Refer toCleaning window and wiper bladesin the
Cleaningchapter.
Changing the wiper blades
To make changing the wiper blades easy, turn the ignition to ACC, then
turn the wipers on. When the wipers reach the vertical position, turn the
ignition to LOCK.

•Remove particles such as bird droppings, tree sap, insect deposits, tar
spots, road salt and industrial fallout before repairing paint chips.
•Always read the instructions before using the products.
ALUMINUM WHEELS AND WHEEL COVERS
Aluminum wheels and wheel covers are coated with a clearcoat paint
finish. In order to maintain their shine:
•Clean weekly with Motorcraft Wheel and Tire Cleaner (ZC-37–A),
which is available from your dealer. Heavy dirt and brake dust
accumulation may require agitation with a sponge. Rinse thoroughly
with a strong stream of water.
•Never apply any cleaning chemical to hot or warm wheel rims or
covers.
•Some automatic car washes may cause damage to the finish on your
wheel rims or covers. Chemical-strength cleaners, or cleaning
chemicals, in combination with brush agitation to remove brake dust
and dirt, could wear away the clearcoat finish over time.
•Do not use hydrofluoric acid-based or high caustic-based wheel
cleaners, steel wool, fuels or strong household detergent.
•To remove tar and grease, use Ford Extra Strength Tar and Road Oil
Removal (B7A-19520–AA), available from your dealer.
ENGINE
Engines are more efficient when they are clean because grease and dirt
buildup keep the engine warmer than normal. When washing:
•Take care when using a power washer to clean the engine. The
high-pressure fluid could penetrate the sealed parts and cause
damage.
•Do not spray a hot engine with cold water to avoid cracking the
engine block or other engine components.
•Spray Motorcraft Engine Shampoo and Degreaser (ZC-20) on all parts
that require cleaning and pressure rinse clean.

WINDSHIELD WASHER FLUID
Add fluid to fill the reservoir if the
level is low. In very cold weather, do
not fill the reservoir completely.
Only use a washer fluid that meets
Ford specification WSB-M8B16–A2.
Refer toLubricant specifications
in this chapter.
State or local regulations on volatile organic compounds may restrict the
use of methanol, a common windshield washer antifreeze additive.
Washer fluids containing non-methanol antifreeze agents should be used
only if they provide cold weather protection without damaging the
vehicle’s paint finish, wiper blades or washer system.
If you operate your vehicle in temperatures below 4.5° C
(40° F), use washer fluid with antifreeze protection. Failure to
use washer fluid with antifreeze protection in cold weather could result
in impaired windshield vision and increase the risk of injury or
accident.
Note:Do not put washer fluid in the engine coolant reservoir. Washer
fluid placed in the cooling system may harm engine and cooling system
components.
ENGINE OIL
Checking the engine oil
Refer to the scheduled maintenance guide for the appropriate intervals
for checking the engine oil.
1. Make sure the vehicle is on level ground.
2. Turn the engine off and wait up to 10 minutes for the oil to drain into
the oil pan.
3. Set the parking brake and ensure the gearshift is securely latched in P
(Park).
4. Open the hood. Protect yourself from engine heat.

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.
Adding engine coolant
When adding coolant, make sure it is a 50/50 mixture of engine coolant
and distilled water. Add the mixture to the coolant reservoir,when the
engine is cool, until the appropriate fill level is obtained.
Do not add engine coolant when the engine is hot. Steam and
scalding liquids released from a hot cooling system can burn you
badly. Also, you can be burned if you spill coolant on hot engine parts.
Do not put engine coolant in the windshield washer fluid
container. If sprayed on the windshield, engine coolant could
make it difficult to see through the windshield.
•Add Motorcraft Premium Gold Engine Coolant
(yellow-colored), VC-7–A (VC-7–B in Oregon), meeting Ford
Specification WSS-M97B51–A1.

1Use only brake fluids certified to meet Ford specifications. Refer to
Lubricant Specificationsin this chapter. DOT 3 fluid is recommended.
However, if DOT 3 is not available, DOT 4 fluid can be used.
2Ensure the correct automatic transmission fluid is used. MERCONand
MERCONV are not interchangeable. DO NOT MIX MERCONand
MERCONV. Refer to the scheduled maintenance guide to determine
the correct service interval.
3Indicates only approximate dry-fill capacity. Some applications may vary
based on cooler size and if equipped with an in-tank cooler. The amount
of transmission fluid and fluid level should be set by the indication on
the dipstick’s normal operating range.
4Add the coolant type originally equipped in your vehicle.
5Rear axles are considered lubricated for life when the vehicle is used for
normal service. See your scheduled maintenance guide for Severe Duty
requirements.
Traction-Lok axles use 2.1-2.3L (4.50-4.75 pints) of rear axle lubricant.
Add 118 ml (4 oz.) of Additive Friction Modifier XL-3 or equivalent
meeting Ford specification EST-M2C118–A for complete refill of
Traction-Lok rear axle.
Service refill capacities are determined by filling the rear axle 6 mm to
14 mm (1/4 inch to 9/16 inch) below the bottom of the filler hole.
6Use of sythetic or sythetic blend motor oil is not mandatory. Engine oil
need only meet the requirements of Ford specification WSS-M2C153–H
and the API Certification mark.
