2015 FORD F650 fuel

Your vehicle is equipped with two or three maintenance-free batteries
mounted in a covered tray located on the left frame rail. The covered
battery tray, depending upon application, may also have one or two steps
attached.

similar).Pull up on the two rubber
straps on the battery cover and
move them to the side of the
battery in order to remove the lid.

removed.
For longer, trouble-free operation, keep the top of the battery clean and
dry. Also, make sure you tightly fasten the battery cables to the battery
terminals.
If you see any corrosion on the battery or terminals, remove the cables
from the terminals and clean with a wire brush. You can neutralize the
acid with a solution of baking soda and water.
If you plan to store your vehicle for an extended period, disconnect the
negative battery cable. This minimizes the discharge of your battery
during storage.
If the engine cranks but does not start, remove the battery box cover
and check the 40 amp inline fuse located on the battery cable above the
battery.
Because a computer electronically controls your vehicle’s engine, battery
power controls some conditions. When you disconnect the battery or
install a new battery, the engine must relearn its idle and fuel trim
strategy for optimum driveability and performance. To begin this process:
1. With your vehicle at a complete stop, set the parking brake.
2. Put the gearshift in positionP(automatic transmission) or neutral
(manual transmission), turn off all accessories and start the engine.
3. Run the engine until it reaches normal operating temperature.

•Always use a clean sponge or car wash mitt with plenty of water for
best results.
•Dry your vehicle with a chamois or soft, terry cloth towel in order to
eliminate water spotting.
•It is especially important to wash your vehicle regularly during the
winter months, as dirt and road salt are difficult to remove and cause
damage to the vehicle.
•Immediately remove items such as gasoline, diesel fuel, bird droppings
and insect deposits because they can cause damage to your vehicle’s
paintwork and trim over time. Use Motorcraft Bug and Tar Remover
(ZC-42), which is available from an authorized dealer.
•Remove any exterior accessories, such as antennas, before entering a
car wash.
•Suntan lotions and insect repellents can damage any painted surface;
if these substances come in contact with your vehicle, wash off as
soon as possible.
•If your vehicle is equipped with running boards, use Motorcraft Detail
Wash (ZC-3-A), and, as required, Motorcraft Bug and Tar Remover
(ZC-42), both as per the directions on the products’ labels. To
manually dry, use a clean, dry, lint-free towel. Do not use rubber,
plastic and vinyl protectant products on the running board surface, as
the area may become slippery.
Exterior Chrome
•Wash your vehicle first, using cool or lukewarm water and a neutral
pH shampoo, such as Motorcraft Detail Wash (ZC-3-A).
•Use Motorcraft Custom Bright Metal Cleaner (ZC-15), available from
an authorized dealer. Apply the product as you would a wax to clean
bumpers and other chrome parts; allow the cleaner to dry for a few
minutes, and then wipe off the haze with a clean, dry rag.
•Never use abrasive materials, such as steel wool or plastic pads, as
they can scratch the chrome surface.
Underbody
Flush the complete underside of your vehicle frequently. Keep body and
door drain holes free from packed dirt.
Rear suspension components may require regular cleaning with a power
washer or a thorough rinse with a strong stream of water if you operate
your vehicle in dusty or muddy environments. Rear leaf springs or other

CLEANING THE ENGINE
Note:To prevent damage to the engine control module, never
spray-wash it directly. Never spray any connector.
Engines are more efficient when they are clean because grease and dirt
build-up 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 on all parts that
require cleaning and pressure rinse clean. In Canada, use Motorcraft
Engine Shampoo.
•Never wash or rinse the engine while it is hot or running; water in
the running engine may cause internal damage.
CLEANING THE WINDOWS AND WIPER BLADES
Clean the windows and wiper blades regularly. If the wipers do not wipe
properly, substances on your vehicle’s glass or the wiper blades may
cause squeaking or chatter noise from the blades, and streaking and
smearing of the windshield. To clean these items follow these tips:
•Clean the windows with a non-abrasive cleaner, such as Motorcraft
Ultra-Clear Spray Glass Cleaner.
•The wiper blades can be cleaned with isopropyl-rubbing alcohol or
Motorcraft Premium Windshield Washer Concentrate in the United
States, or Premium Quality Windshield Washer Fluid in Canada. Be
sure to replace wiper blades when they appear worn or do not
function properly.
•Do not use abrasives, as they may cause scratches.
•Do not use fuel, kerosene, or paint thinner to clean any parts.
If you cannot remove those streaks after cleaning with the glass cleaner
or if the wipers chatter and move in a jerky motion, clean the outer
surface of the windshield and the wiper blades using a sponge or soft
cloth with a neutral detergent or mild-abrasive cleaning solution. After
cleaning, rinse the windshield and wiper blades with clean water. The
windshield is clean if beads do not form when you rinse the windshield
with water.

A clearcoat paint finish coats aluminum wheels and wheel covers. In
order to maintain their condition:
•Clean weekly with Motorcraft Wheel and Tire Cleaner. Use a sponge to
remove heavy deposits of dirt and brake dust accumulation. Rinse
thoroughly with a strong stream of water when you have completed
the cleaning process.
•To remove tar and grease, use Motorcraft Bug and Tar Remover.
•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.
•Industrial-strength (heavy-duty) 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.
•If you intend on parking your vehicle for an extended period after
cleaning the wheels with a wheel cleaner, drive your vehicle for a few
minutes before doing so. This reduces the risk of increased corrosion
of the brake discs.
VEHICLE STORAGE

Checking Tire Pressure
Always check inflation pressure when tires are cold. Never bleed air from
hot tires to relieve normal pressure build-up. Normal increase in pressure
due to service conditions is 10–15 psi (69–103 kPa), which is allowable
in truck tires.
Tires should be properly inflated to manufacturers’ recommended
pressure for the size and service load in which the vehicle is being used.
See the specific tire manufacturer with which your vehicle is equipped
with for the latest information concerning service load and inflation
pressure.
It is particularly important to keep moisture from the inside of tires, and
proper selection of air compressor equipment, proper air line routing,
and the use of shop air dryers is strongly recommended to avoid
moisture in the high pressure air used for tire inflation.
Under-inflation
Do not allow tires to become under-inflated; increased flexing due to
under-inflation causes heat build-up within the tire components. This
leads to reduced strength, breakdown of the rubber compounds, and
possible separation of the tire components (such as ply and tread
separation and reduced retreadability).
Under-inflation is the primary cause of premature tire concerns including
sudden loss of air. In addition, low inflation causes an increase in rolling
resistance. This results in reduced fuel mileage, a loss in tread mileage,
and uneven wear due to increased tread movement. To determine proper
inflation, see the tire manufacturer load and inflation guide, which you
can find on the tire manufacturer website or at your local truck tire
dealer.
Tire Inspection
Check the tires for abnormal wear patterns and proper inflation
pressures. Repair or replace cut or broken tire casings.
Inspect tires for the following conditions. If any are present, remove and
repair, retread, or scrap the tire as the condition dictates.
•Any blister, bump or raised portion anywhere on the surface of the
tire tread or sidewall (other than a bump made by a repair). These
indicate the start of internal separation.
•Any cut that reaches to the belt or ply cords, or any cut that is large
enough to grow in size and depth.
•Any nail or puncturing object.
•If a tread groove is holding a stone or object that is starting to drill
into the tread base, remove the object.
