•On some engines, theWait to
startlight should illuminate after
the engine starts. Allow the
engine to idle about three
minutes or until the engine
coolant temperature gauge begins to rise. Maintain idle speed until the
Wait to startlight cycles off to indicate the air intake heater has shut
off (approximately six minutes). Operating the engine at higher
speeds will reduce the effectiveness of the air inlet heater.
•Do not increase engine speed
until the oil pressure gauge
indicates normal pressure.
•Ensure engine oil pressure is
indicated on the gauge within 15
seconds after starting.
•Idle the engine for three to five
minutes before operating with a
full load.
•Try to limit engine idle to 10 minutes. Excessive idling reduces fuel
economy.
•When starting a cold engine, increase the engine speed (RPM) slowly
to make sure adequate lubrication is available to the bearings.
Restarting after running out of fuel
The fuel system may need to be purged of air, refer toRunning out of
fuelin theMaintenance and specificationschapter.
Cold weather starting
Perform the following to assure efficient starting in cold weather:
•Use the proper grade oil for your climate. Refer to your engine
operator’s manual for proper grade oil.
•Test the battery more frequently to assure ample power for starting.
•All electrical connections should be tight and in good condition to
prevent losses through loose or corroded connections.
Using the engine block heater (if equipped)
Use of an engine block heater is strongly recommended if you live in a
region where temperatures reach -23°C (-10°F) or below. For best
results, plug the heater in at least three hours before starting the vehicle.
The heater can be plugged in the night before starting the vehicle.WAIT

WINDSHIELD WASHER FLUID
Checking and adding washer fluid
Inspect the solution level in the
washer reservoir when insufficient
solution is sprayed.
Use 3.8L (4.0 quarts) of
Ultra—Clear Windshield Washer
Concentrate or a washer fluid that
meets the Ford specification listed.
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.
Do not put engine coolant or antifreeze in the washer fluid
reservoir. Engine coolant or antifreeze can severely reduce
visibility if sprayed on the windshield.
ENGINE OIL
Checking engine oil level—Cummins B and Caterpillar 3126 B
engines
Refer to the appropriate engine operator’s manual for information on the
engine oil.
Checking engine oil level—7.3L Power Stroke engine
Refer to the general maintenance information section for the appropriate
intervals for checking the engine oil.
Check the engine oil level consistently and accurately. The following
procedure is recommended:
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. Park the vehicle on level ground.

Engine oil and filter recommendations—7.3L Power Stroke engine
To help achieve proper engine performance and durability, it is important
that you:
•Use only engine lubricating oils and oil filters of the proper quality.
•Change the engine oil and filterno laterthan the recommended
service interval. Refer to the general maintenance information section
for the appropriate intervals for changing the engine oil and filter.
•Change your engine oil and filter more frequently if your vehicle
operation includes extended periods of idling or low-speed operation,
driving for a long time in cold temperatures or short driving distances.
Diesel engines require specially formulated oil to resist contamination.
Proper quality oils also provide maximum efficiency of the crankcase
ventilation system which reduces air pollution.
For normal or severe service, use Motorcraft oil or an equivalent oil
conforming to Ford Specification WSS-M2C171–C or API Service
categories CH-4, CH-4/SJ or CH-4/SL. If CH-4 oil is not available, CG-4 is
acceptable.
Diesel engine oils with improved fuel economy properties (energy
conserving) are currently available. If you use an energy conserving oil,
be sure it meets Ford specification WSS-M2C171–C or API service
category designation CH-4/SL and is of the proper viscosity grade for the
temperature range in which you expect to operate your vehicle. Some
energy conserving oils do not meet the requirements necessary for your
diesel engine.

1. Before you begin, turn the engine off and let it cool.
2. When the engine is cool, wrap a thick cloth around the coolant
pressure relief cap on the coolant reservoir (an opaque plastic bottle).
Slowly turn cap counterclockwise (left) until pressure begins to release.
3. Step back while the pressure releases.
4. When you are sure that all the pressure has been released, use the
cloth to turn it counterclockwise and remove the cap.
5. Fill the coolant reservoir slowly with the proper coolant mixture (see
above), to within the“cold fill range”or the“cold full”level on the
reservoir. If you removed the radiator cap in an overflow system, fill the
radiator until the coolant is visible and radiator is almost full.
6. Replace the cap. Turn until tightly installed. (Cap must be tightly
installed to prevent coolant loss.)
After any coolant has been added, check the coolant concentration see
Checking Engine Coolant section). If the concentration is not 50/50
(protection to–34°F/–36°C), drain some coolant and adjust the
concentration. It may take several drains and additions to obtain a 50/50
coolant concentration.
Whenever coolant has been added, the coolant level in the coolant
reservoir should be checked the next few times you drive the vehicle. If
necessary, add enough 50/50 concentration of engine coolant and
distilled water to bring the liquid level to the proper level.
If you have to add more than 1.0 liter (1.0 quart) of engine coolant per
month, have your dealer check the engine cooling system. Your cooling
system may have a leak. Operating an engine with a low level of coolant
can result in engine overheating and possible engine damage.
Replacing coolant
A coolant mixture of 50% coolant concentrate and 50% water is
recommended to maintain best overall performance. To avoid damaging
the engine and radiator, the coolant concentrate should not exceed 60%.
When refilling the coolant system either as part of the regular
maintenance (refer to the general maintenance information section), or
due to service performed, adhere to the following instructions:
1. Drain and flush the cooling system to remove dirt deposits, oil, rust
particles.
Note:
When filling the system with Motorcraft Premium Engine Coolant
(green-colored) or equivalent meeting Ford specification ESE-M97B44–A, a
supplemental coolant additive is required. Refer toAdding Coolantsection

Fuel filter replacement—Caterpillar 3126 B engine
The fuel filter/water separator is
located on the left side of the
engine. Replace the fuel filter/water
separator as recommended in the
general maintenance information
section, or sooner if it becomes
plugged. Vehicles operated on fuel
with more than average impurities
may require replacement of the fuel
filter more frequently. The spin-on
filter has a water drain valve built
into the bottom of the filter canister.
Removal
1. Using an oil filter wrench, remove the filter.
2. Carefully clean the mating surfaces.
Installation
1. Fill the filter with clean, fresh diesel fuel.
2. Coat the filter seal with clean, fresh diesel fuel.
3. Hand-tighten the filter until it seats firmly against the mount, then
tighten (by hand) an additional
1⁄3to1⁄2turn.
4. Start the engine and check for fuel leaks.
