2003 FORD SUPER DUTY tow

IMPORTANT NOTICE
Ford vehicles are suitable for producing ambulances only if equipped
with theFord Ambulance Preparation Package.In addition, Ford
urges ambulance manufacturers to follow the recommendation of the
Ford Incomplete Vehicle Manual, Ford Truck Body Builder’s Layout
Book(and pertinent supplements) and theQualified Vehicle Modifiers
Guidelines. Using a Ford vehicle without theFord Ambulance
Preparation Packageto produce an ambulance voids the Ford warranty
and could result in elevated underbody temperatures, fuel
overpressurization and the risk of fuel expulsion and fires. To determine
whether the vehicle is equipped with theFord Ambulance Preparation
Package,inspect the information plate on the driver’s side door pillar.
Contact the manufacturer of your vehicle to determine whether the
ambulance manufacturer’s followed Ford’s recommendations.
WARNINGS
Throughout this guide, you will find warnings. Warnings remind you to
be especially careful to avoid personal injury.
NEW VEHICLE BREAK-IN
Your vehicle does not need an extensive break-in. Try not to drive
continuously at the same speed for the first 1,600 km (1,000 miles) of
new vehicle operation. Vary your speed to allow parts to adjust
themselves to other parts.
Drive your new vehicle at least 800 km (500 miles) before towing a
trailer.
Do not add friction modifier compounds or special break-in oils during
the first few thousand kilometers (miles) of operation, since these
additives may prevent piston ring seating. SeeEngine oilin theGeneral
maintenance informationchapter for more information on oil usage.

* Heavy duty trailer towing with ambient temperatures above 10°C
(50°F) requires 15W-40 engine oil.
The use of correct oil viscosities for Diesel engines is important for
satisfactory operation. Determine which oil viscosity best suits the
temperature range you expect to encounter for the next service interval.
A symbol has been developed by the
American Petroleum Institute (API)
to help you select the proper engine
oil. It will be included on the oil
container you purchase. The top
section of the symbol shows the oil
performance by the API designation.
This should match the owner guide recommendation. The center section
will show the SAE viscosity grade. The lower section will state energy
conserving if the oil has proven fuel saving capabilities.
Changing engine oil and filter
Change your oil and filter according to the scheduled maintenance guide.
Change more frequently if your vehicle operation includes extended
periods of idling or low-speed operation, driving for a long time in cold
temperatures or driving short distances. See the following section
Engine lubrication for severe service operationfor all severe duty
restrictions.
Use Ford Engine Oil Filter Part No. 3C3Z-6731–AA (FL–2016) or
equivalent. These filters protect your engine by filtering harmful,
abrasive or sludge particles. The FL–2016 filters particles significantly
smaller than most available“will-fit”filters.

To replace the filter,
1. Unscrew the oil filter cap and wait a few seconds for the oil to drain
through the built-in drain valve.Note:The filter should be changed
before reinstalling the oil pan drain plug.
2. Reinstall and tighten the oil filter cap.
Do not handle a hot oil filter with bare hands.
Continuous contact with USED motor oil has caused cancer in
laboratory mice. Protect your skin by washing with soap and
water.
Engine lubrication for severe service operation
The following severe service operating conditions require unique engine
maintenance procedures:
•towing a trailer over 1,600 km (1,000 miles)
•sustained, high speed driving at Gross Vehicle Weight Rating
(maximum loaded weight for vehicle operation during hot
weather-above 32°C [90°F]).
•frequent or extended idling (over 10 minutes per hour of normal
driving).
•operating in severe dust conditions.
•frequent, short trips of 16 km (10 miles) or less during freezing
weather
If you are operating your vehicle under any of these conditions, observe
the following service procedures:
•Change engine oil and filter every 8,000 km (5,000 miles).
•Use Motorcraft oil or an equivalent oil conforming to Ford
Specification WSS-M2C171–D or API categories CI-4, CI–4/SL or
DHD-1. If CI-4 oil is not available, CH-4 is acceptable.
For more information refer theSevere duty maintenance schedulein
the scheduled maintenance guide.
