2007 FORD F SERIES MOTORHOME AND COMMERCIAL CHASSIS service interval

•Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
•Consult your local motor vehicle speed regulations for towing a trailer.
•To eliminate excessive shifting, use a lower gear. This will also assist
in transmission cooling.
•Anticipate stops and brake gradually.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to yourscheduled maintenance
informationfor more information.
Trailer towing tips
•Practice turning, stopping and backing up before starting on a trip to
get the feel of the vehicle trailer combination. When turning, make
wider turns so the trailer wheels will clear curbs and other obstacles.
•Allow more distance for stopping with a trailer attached.
•If you are driving down a long or steep hill, shift to a lower gear. Do
not apply the brakes continuously, as they may overheat and become
less effective.
•The trailer tongue weight should be 10–15% of the loaded trailer
weight.
•If you will be towing a trailer frequently in hot weather, hilly
conditions, at GCWR, or any combination of these factors, consider
refilling your rear axle with synthetic gear lube if not already so
equipped. Refer to theMaintenance and Specificationschapter for
the lubricant specification. Remember that regardless of the rear axle
lube used, do not tow a trailer for the first 500 miles (800 km) of a
new vehicle, and that the first 500 miles (800 km) of towing be done
at no faster than 70 mph (112 km/h) with no full throttle starts.
•After you have traveled 50 miles (80 km), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
•To aid in engine/transmission cooling and A/C efficiency during hot
weather while stopped in traffic, place the gearshift lever in P (Park).
•Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer’s wheels.

Your vehicle was factory-filled with a 50/50 engine coolant and water
concentration. If the concentration of coolant falls below 40% or above
60%, the engine parts could become damaged or not work properly.A
50–50 mixture of coolant and water provides the following:
•Freeze protection down to -34°F (-36°C).
•Boiling protection up to 265°F (129°C).
•Protection against rust and other forms of corrosion.
•Enables calibrated gauges to work properly.
When the engine is cold, check the
level of the engine coolant in the
reservoir.
•The engine coolant should be at the “FULL COLD” level or within the
“COLD FILL RANGE” as listed on the engine coolant reservoir
(depending upon application).
•Refer toscheduled maintenance informationfor 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.

POWER STEERING FLUID
Check the power steering fluid.
Refer toscheduled maintenance
informationfor the service interval
schedules. If adding fluid is
necessary, use only MERCONAT F.
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 on the
dipstick. It should be between the
arrows in the FULL range on the
side of the dipstick with the words
MAX. HOT at the top. Do not add
fluid if the level is within this range.
5. If the fluid is low, add fluid in small amounts, continuously checking
the level until it reaches the FULL range. Be sure to put the dipstick
back in the reservoir.

BRAKE FLUID
Brake fluid should be checked and refilled as needed. Refer to the
scheduled maintenance informationfor the service interval schedules.
•Hydromaxbrake fluid reservoir
Chassis with Gross Vehicle Weight Ratings of 20,500 lb (9,299 kg) and
22,000 lb (9,979 kg) are equipped with Hydromax Brake Booster
Systems and must use Motorcraft Super DOT 4 Motor Vehicle Brake
Fluid or equivalent meeting Ford Specification ESD-M6C57-A. Refer to
Maintenance product specifications and capacitiesin this chapter.
•Hydroboostbrake fluid reservoir
Chassis with Gross Vehicle Weight Ratings of 16,000 lb (7,257 kg) and
18,000 lb (8,165 kg) are equipped with Hydroboost Brake Booster
Systems and must use Motorcraft High Performance DOT 3 Motor
Vehicle Brake Fluid or equivalent meeting Ford Specification
ESA-M6C25-A or WSS-M6C62-A. Refer toMaintenance product
specifications and capacitiesin this chapter..
Note:On Hydromax brake systems a clear gel-like substance in the
hydraulic brake master cylinder reservoir may appear on some vehicles.
This substance is a silicone base lubricant used during assembly of the
master cylinder. It will float on top of the brake hydraulic fluid in the
master cylinder. This condition is normal and in no way affects the
operation of the brake system. It does not require any service.

1. Clean the reservoir cap before removal to prevent dirt or water from
entering the reservoir.
2. Visually inspect the fluid level.
3. If necessary, add brake fluid from a clean un-opened container until
the level reaches MAX. Do not fill above this line.
4. Use only a brake fluid listed previously (DOT 3 or Super DOT 4
depending on brake system) and that is certified to meet Ford
specifications. Refer toMaintenance product specifications and
capacitiesin this chapter.
Carefully read cautionary information on product label. For
MEDICAL EMERGENCY INFORMATION contact a physician or
Poison Control Center immediately; on Ford-Motorcraft products call:
1-800-959-3673 (FORD). Failure to follow these instructions may result
in personal injury.
Use of any brake fluid other than that indicated for your brake
system will cause permanent damage.
Do not let the reservoir for the master cylinder run dry. This
may cause the brakes to fail.
Brake system fluid should be replaced on a regular basis to maintain
optimum braking performance, especially under heavy-duty driving
conditions such as frequent steep grades or heavy towing loads. Refer to
scheduled maintenance informationfor the service interval schedules.

Adjusting automatic transmission fluid levels
Before adding any fluid, make sure the correct type is used. The type of
fluid used is normally indicated on the dipstick and also in the
Maintenance product specifications and capacitiessection in this
chapter.
Use of a non-approved automatic transmission fluid may cause
internal transmission component damage.
If necessary, add fluid in 1/2 pint (250 ml) increments through the filler
tube until the level is correct.
If an overfill occurs, excess fluid
should be removed by an authorized
dealer.
An overfill condition of
transmission fluid may cause shift and/or engagement concerns
and/or possible damage.
Do not use supplemental transmission fluid additives, treatments or
cleaning agents. The use of these materials may affect transmission
operation and result in damage to internal transmission components.
Automatic transmission fluid filter (if equipped)
The TorqShift automatic
transmission may be equipped with
a serviceable external fluid filter
mounted near the radiator on the
passenger side of the engine. Refer
toscheduled maintenance
informationfor service intervals.
Vehicles which do not have the
externally mounted filter will have
the transmission fluid filter located
inside the transmission bottom pan.
See your authorized dealer for replacement.
To replace the external mounted fluid filter:
1. Shut off the engine.
2. Unscrew filter housing.
3. Replace filter with a new authorized Motorcraft filter element. Refer to
theMotorcraft part numberschart in this chapter.
4. Reinstall housing and check transmission fluid level using procedure in
this section.

Your vehicle’s rear axle is filled with a synthetic rear axle lubricant and is considered lubricated for
life. These lubricants do not need to be checked or changed unless a leak is suspected, service is
required or the axle assembly has been submerged in water. The axle lubricant should be changed
any time the rear axle has been submerged in water.6Fill 1/4 inch to 9/16 inch (6 mm to 14 mm) below bottom of fill hole.
