•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.
WARNING:Do not put engine coolant in the windshield washer
fluid container. If sprayed on the windshield, engine coolant
could make it difficult to see through the windshield.
•DO NOT MIXdifferent colors or types of coolant in your vehicle.
Make sure the correct coolant is used. Mixing of engine coolants may
harm your engine’s cooling system. The use of an improper coolant
may harm engine and cooling system components and may void the
warranty. Refer toMaintenance product specifications and
capacitiesin this chapter.
Note:Do not use stop leak pellets or cooling system sealants/additives
as they can cause damage to the engine cooling and/or heating systems.
This damage would not be covered under your vehicle’s warranty.
•A large amount of water without engine coolant may be added, in case
of emergency, to reach a vehicle service location. In this instance, the
cooling system must be drained, chemically cleaned with Motorcraft
Premium Cooling System Flush, and refilled with a 50/50 mixture of
engine coolant and distilled water as soon as possible. Water alone
(without engine coolant) can cause engine damage from corrosion,
overheating or freezing.

GENERAL MAINTENANCE INFORMATION
Why maintain 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 as
identified in theMaintenance and Specificationschapter. 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.
Genuine Ford and Motorcraftreplacement parts
Dealerships stock Ford and Motorcraftbranded replacement parts.
These parts meet or exceed Ford Motor Company’s specifications, and
we stand behind them. Parts installed at your dealership carry a
nationwide, 12 month/12,000 mile (20,000 km) parts and labor limited

EXCEPTIONS
There are several exceptions to the Normal Schedule. They are listed
below:
Normal vehicle axle maintenance:Rear axles and power take-off
(PTO) units with synthetic fluid and light-duty trucks equipped with
Ford-design axles are lubricated for life; do not check or change fluid
unless a leak is suspected, service is required or the assembly has been
submerged in water. During long periods of trailer towing with outside
temperatures above 70°F (21°C) and at wide-open throttle for long
periods above 45 mph (72 km/h), non-synthetic rear axle fluids should
be changed every 3,000 miles (4,800 km) or three months, whichever
comes first. This interval can be waived if the axle is filled with 75W140
synthetic gear fluid meeting Ford specification WSL-M2C192-A, part
number F1TZ-19580-B or equivalent. Add friction modifier XL-3
(EST-M2C118-A) or equivalent for complete refill of Traction-Lok rear
axles (refer toMaintenance product specifications and capacitiesin
theMaintenance and Specificationschapter for details).
Police/Taxi/Livery vehicle axle maintenance:Change rear axle fluid
every 100,000 miles (160,000 km). Rear axle fluid change may be waived
if the axle was filled with 75W140 synthetic gear fluid meeting Ford
specification WSL-M2C192-A, part number FITZ-19580-B or equivalent.
Add four ounces (118 mL) of additive friction modifier XL-3
(EST-M2C118-A) or equivalent for complete refill of Traction-Lok rear
axles. The axle fluid should be changed anytime the axle has been
submerged in water.
E–450 and F–450/550 axle maintenance:Change rear axle fluid every
100,000 miles (160,000 km) under normal driving conditions. For
vehicles operated at or near maximum Gross Vehicle Weights, the rear
axle fluid should be changed every 50,000 miles (80,000 km). In
addition, this 50,000 mile (80,000 km) schedule should be observed
when the vehicles are operated under the Special Operating Conditions.
California fuel filter replacement:If the vehicle is registered in
California, the California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify the emission
warranty or limit recall liability prior to the completion of the vehicle’s
useful life. Ford Motor Company, however, urges you to have all
recommended maintenance services performed at the specified intervals
and to record all vehicle service.
