power steering fluid and hydraulic brake fluid. Failure to observe
precautions preventing the contamination of either system with fluid
from the other will result in swelling and deterioration of rubber parts
leading to reduced brake performance and eventual brake failure.
To avoid fluid contamination, the following should always be observed:
1. Use only fluids specified (or equivalent) and properly identified.
2. Add fluids only to the following locations:
•Power steering fluid to the power steering fluid pump reservoir
• Brake fluid to the brake master cylinder
Hydraulic brakes - brake lines, hoses and fittings
Inspect these components every 4,000 miles (6,000 km).
• Check lines for kinks, dents, corrosion or rupture.
• Check hoses for abrasions, kinks, soft spots or rupture, collapse,
cracks, twists or loose frame supports. When replacing a hose, be sure
there is adequate clearance to the hose to avoid an abrasion to the
new hose.
• Examine all connections for leaks.
• Repair or replace brake line tubes, hoses or fittings as required.
Driveline parking brake
Parking brake adjustment should only be performed by a qualified
technician, and in accordance with the instructions in the service
manual.
Use wheel chocks and exercise caution when inspecting under
the vehicle. A vehicle roll-away could result in property damage,
personal injury or death.
Catalytic converter
If your diesel engine is equipped with a catalytic converter, it is
important to review the maintenance schedule to ensure proper
functioning of the catalytic converter. Also, take precautions not to
damage the catalytic converter when servicing your engine or storing
your vehicle.
Note: If your vehicle is equipped with a catalytic converter/muffler, do
not blend waste oil with Diesel fuel. Operate only on low sulfur (less
than 500 parts per million sulfur) diesel fuel with a cetane value of 45 or
higher.

•Check that pitman arm (steering arm at steering gear) mounting is
tight and locked. Check system for leaks or hose chafing. Repair at
once.
• Maintain proper steering gear and power steering pump lubricant
levels.
• Regularly inspect steering column joint bolts and steering linkage,
particularly for body-to-chassis clearance.
Note: Have any steering problems corrected at once by a qualified
service technician.
Failure to maintain the steering system in proper condition can
cause reduced steering ability resulting in property damage,
personal injury or death.
Tightening steering column joint bolts
As a good maintenance practice, it is recommended that steering column
joint bolts be checked for tightness every 60,000 miles (96,000 km) or
annually, whichever occurs first. DO NOT OVERTIGHTEN.
Power steering
Whenever the power steering’s hydraulic system has been drained and
refilled for any reason, air must be bled from the system before returning
the vehicle to service. Failure to properly bleed the hydraulic system can
result in degradation of power system performance.
Consult your dealer who is aware of the proper procedures for filling and
bleeding the system.
OPENING THE HOOD
The hood and fenders are held in position by a latch located on each
fender.
The parking brake must be fully set before opening the hood or
possible personal injury may occur.
To reduce the risk of the possibility of personal injury, never
stand beneath the hood when it is being raised or lowered.

CHANGING THE WIPER BLADES
To replace the wiper blades:
1. Pull the wiper arm away from the
windshield and lock into the service
position.
2. Turn the blade at an angle from
the wiper arm. Push the lock pin
manually to release the blade and
pull the wiper blade down toward
the windshield to remove it from the
arm.
3. Attach the new wiper to the
wiper arm and press it into place
until a click is heard.
ENGINE OIL
Checking the engine oil
Refer to the Scheduled Maintenance Guide chapter for the appropriate
intervals for checking the engine oil. Check the engine oil level
consistently and accurately.
If your vehicle is equipped with a Cummins or Caterpillar engine,
refer to the appropriate engine operator’s manual for information on the
engine oil.
If your vehicle is equipped with the 6.0L Power Stroke engine,
perform the following procedure:
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.
3. Set the parking brake and shift into N (Neutral) (automatic
transmission) or 1 (First) (manual transmission).

POWER STEERING FLUID
Check the power steering fluid level using the following procedure. If
adding fluid is necessary, refer toLubricant Specificationsin this
chapter for the proper fluid type. Refer to theScheduled Maintenance
Guidechapter for the recommended service intervals.
1. Set the parking brake, shift into N (Neutral) (automatic transmission)
or 1 (First) (manual transmission) and turn the engine off.
2. Open the hood.
3. Clean the top of the power steering fluid reservoir.

CLUTCH FLUID/LINKAGE ADJUSTMENTS
Clutch fluid (if equipped)
Check the clutch fluid level. Refer to theScheduled Maintenance
Guidechapter for the service interval schedules.
During normal operation, the fluid level in the clutch reservoir should
remain constant. If the fluid level drops, maintain the fluid level at the
step in the reservoir.
Use only a DOT 3 brake fluid designed to meet manufacturer
specifications. Refer toLubricant specificationsin this chapter.
Carefully read cautionary information on product label. For
additional information see product Material Safety Data Sheet
(MSDS). For 24-hour MEDICAL EMERGENCY INFORMATION on
Ford-Motorcraft products call: 1-800-959-3673 (FORD). Failure to
follow these instructions may result in personal injury
1. Set the parking brake, shift into 1

TRANSMISSION FLUID
Always dispose of used automotive fluids in a responsible manner.
Follow your community’s standards for disposing of these types of fluids.
Call your recycling center to find out about recycling automotive fluids.
Automatic transmission fluid
Refer to your Allison Automatic Transmission Operator’s Manual for
scheduled intervals for transmission fluid checks and changes. Your
transmission does not consume fluid. However, the fluid level should be
checked if the transmission is not working properly, i.e., if the
transmission slips or shifts slowly or if you notice some sign of fluid
leakage.
Automatic transmission fluid expands when warmed. To obtain an
accurate fluid check, drive the vehicle until it is warmed up
(approximately 20 miles [30 km]). If your vehicle has been operated for
an extended period at high speeds, in city traffic or during hot weather,
the vehicle should be turned off for about 30 minutes to allow fluid to
cool before checking.
1. Drive the vehicle 20 miles (30 km) or until it reaches normal operating
temperature.

2. Park the vehicle on a level surface and engage the parking brake.
3. With the parking brake engaged and your foot on the brake pedal,
start the engine and move the gearshift lever through all of the gear
ranges. Allow sufficient time for each gear to engage.
4. Place the gearshift lever in N (Neutral) or P (Park) and leave the
engine running.
5. Remove the dipstick, wiping it clean with a clean, dry lint free rag.
6. Install the dipstick making sure it is fully seated in the filler tube.
7. Remove the dipstick and inspect the fluid level.
If you must add transmission fluid, make sure the correct type of fluid is
being used. The type of fluid used is indicated in your Allison Automatic
Transmission Operator’s Manual.
Fluid levels above the safe range may result in transmission failure; an
overfill condition of transmission fluid may cause shift and/or
engagement concerns and/or possible damage.
Use of a non-approved automatic transmission fluid may cause
internal transmission component damage.
Manual transmission fluid
Refer to theScheduled Maintenance Guidechapter for transmission
fluid level checks and fluid change intervals.
Your manual transmission may be filled with an optional synthetic fluid
which allows the use of extended service intervals. A tag on the filler
plug will identify the use of the synthetic fluid.
Use only fluid that meets manufacturer specifications (refer to
Lubricant specificationsin this chapter.
Use of a non-approved transmission fluid may cause internal
transmission component damage.
Check your transmission fluid level using the following procedure:
1. Park the vehicle on level ground.
2. Set the parking brake and shift into 1 (First) and turn the engine off.
3. Clean any dirt from around the filler plug.
4. Remove the filler plug and inspect the fluid level.
5. The fluid level should be up to the bottom of the filler plug opening.
6. If necessary, add enough fluid through the filler plug opening so that
the fluid level is at the bottom of the opening.
