2011 FORD F SERIES MOTORHOME AND COMMERCIAL CHASSIS service interval

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 or MIN / MAX range as listed on the engine coolant
reservoir (depending upon application).
•Refer toscheduled maintenance informationfor service interval
schedules.
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. If coolant is
filled to the COLD FILL RANGE or FULL COLD level when the engine is
not cool, the system will remain underfilled.
WARNING: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.

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 (Hydroboost system only). Do not fill above this
line.
•For vehicles with the Hydromax
brake system, add fluid up to the
bottom of the rings located at the
top of the reservoir. 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.

WARNING: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
The Torqshift automatic transmission is equipped with a serviceable
transmission fluid filter located inside the transmission bottom pan.
Refer toscheduled maintenance informationfor service intervals for
automatic transmission fluid and transmission filter.
For transmission filter maintenance, see your authorized dealer.

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.

GENERAL MAINTENANCE INFORMATION
Why maintain your vehicle?
This guide describes the scheduled maintenance required for your vehicle.
Carefully following this schedule helps protect against major repair
expenses resulting from neglect or inadequate maintenance and may also
help to increase the value of your vehicle when you sell or trade it.
It is your responsibility to see that all scheduled maintenance is performed
and that the materials used meet Ford engineering specifications. Failure
to perform scheduled maintenance specific in this guide will invalidate
warranty coverage on parts affected by the lack of maintenance. Be sure
receipts for completed maintenance are kept with the vehicle and
confirmation of the work performed is always recorded in this guide.
Your dealer has factory-trained technicians who can perform the required
maintenance using genuine Ford parts. They are committed to meeting
your service needs and to assuring your continuing satisfaction.
Protecting your investment
Maintenance is an investment that will pay dividends in the form of
improved reliability, durability and resale value. To ensure the proper
performance of your vehicle and its emission control systems, it is imperative
that scheduled maintenance be completed at the designated intervals.
Your vehicle is very sophisticated and built with multiple complex
performance systems. Every manufacturer develops these systems using
different specifications and performance features. That’s why it’s important
to rely upon your dealership to properly diagnose and repair your vehicle.
Ford Motor Company has recommended maintenance intervals for various
parts and component systems based upon engineering testing. Ford Motor
Company relies upon this testing to determine the most appropriate
mileage for replacement of oils and fluids to protect your vehicle at the
lowest overall cost to you and recommends against maintenance schedules
that deviate from the scheduled maintenance information.
Ford strongly recommends the use of genuine Ford replacement parts.
Parts other than Ford, Motorcraftor Ford-authorized remanufactured
parts that are used for maintenance replacement or for the service of
components affecting emission control must be equivalent to genuine
Ford Motor Company parts in performance and durability. It is the
owner’s responsibility to determine the equivalency of such parts. Please
consult yourWarranty Guidefor complete warranty information.
Chemicals or additives not approved by Ford are not required for factory
recommended maintenance. In fact, Ford Motor Company recommends
against the use of such additive products unless specifically
recommended by Ford for a particular application.

Oils, fluids and flushing
In many cases, fluid discoloration is a normal operating characteristic
and, by itself, does not necessarily indicate a concern or that the fluid
needs to be changed. However, discolored fluids that also show signs of
overheating and/or foreign material contamination should be inspected
immediately by a qualified expert such as the factory-trained technicians
at your dealership. Your vehicle’s oils and fluids should be changed at the
specified intervals or in conjunction with a repair. Flushing is a viable
way to change fluid for many vehicle sub-systems during scheduled
maintenance. It is critical that systems are flushed only with new fluid
that is the same as that required to fill and operate the system, or using
a Ford-approved flushing chemical.
Genuine Ford parts and service
When planning your maintenance services, consider your dealership for
all your vehicle’s needs.
There are a lot of reasons why visiting your dealership for all your
service needs is a great way to help keep your vehicle running great.
Convenience
Many dealerships have extended evening and Saturday hours to make
your service visit more convenient. How’s that for quality service?
Factory-trained technicians
Service technicians participate in extensive factory-sponsored
certification training to help them become experts on the operation of
your vehicle. Ask your dealership about the training and certification
their technicians have received.

Owner checks and services
Certain basic maintenance checks and inspections should be performed
by the owner or a service technician at the intervals indicated. Service
information and supporting specifications are provided in this owner’s
guide.
Any adverse condition should be brought to the attention of your dealer
or qualified service technician as soon as possible for the proper service
advice. The owner maintenance service checks are generally not covered
by warranties so you may be charged for labor, parts or fluids used.
