1998 FORD E SERIES engine

DRIVING THROUGH WATER
Do not drive quickly through standing water, especially if the depth is
unknown. Traction or brake capability may be limited and if the ignition
system gets wet, your engine may stall. Water may also enter your
engine's air intake and severely damage your engine.
If driving through deep or standing water is unavoidable, proceed very
slowly. Never drive through water that is higher than the bottom of the
hubs (truck)/wheel rims (car).
Once through the water, always try the brakes. Wet brakes do not stop
the vehicle as effectively as dry brakes. Drying can be improved by
moving your vehicle slowly while applying light pressure on the brake
pedal.
TRAILER TOWING
Your vehicle may tow a class I, II or III trailer provided the maximum
trailer weight is less than or equal to the maximum trailer weight listed
for your engine and rear axle ratio on the following charts.

Maximum loaded trailer weight of 4 717 kg (10 400 lbs.) on 7.3L E350
RV and commercial cutaways (single rear wheel) applicable to fifth
wheel trailer usage only. Otherwise, maximum trailer weight is 4 536 kg
(10 000 lbs.).
For high altitude operation reduce GCWR by 2% per 300 meters
(1 000 ft) elevation.
To determine the maximum trailer weight designed for you particular
vehicle as equipped, follow the sectionCalculating the load your
vehicle can tow/carryearlier in this chapter.
Driving
73

Your vehicle's load capacity is designated by weight, not by volume, so
you cannot necessarily use all available space when loading a vehicle.
Distribute the load so that only 10 to 15% of the total is on the tongue.
Tie down the load so that it does not shift and change the weight on the
hitch.
Towing a trailer places an additional load on your vehicle's engine,
transmission, axle, brakes, tires and suspension. Inspect these
components carefully after any towing operation.
Do not exceed the GVWR or the GAWR specified on the Safety
Compliance Certification Label.
Towing trailers beyond the maximum recommended gross trailer
weight could result in engine damage, transmission/axle damage,
structural damage, loss of control, and personal injury.
Preparing to tow
Use the proper equipment for towing a trailer, and make sure it is
properly attached to your vehicle. See your dealer or a reliable trailer
dealer if you require assistance.
Hitches
Do not use or install hitches that clamp onto the bumper or to the axle.
Underbody hitches are acceptable if installed properly.
Safety chains
Always connect the trailer's safety chains to the vehicle. To connect the
trailer's safety chains, cross the chains under the trailer tongue and allow
slack for turning corners.
If you use a rental trailer, follow the instructions that the rental agency
gives to you.
Trailer brakes
Electric brakes and manual, automatic or surge-type brakes are safe if
installed properly and adjusted to the manufacturer's specifications. The
trailer brakes must meet local and Federal regulations.
Do not connect a trailer's hydraulic brake system directly to your
vehicle's brake system. Your vehicle may not have enough
braking power and your chances of having a collision greatly increase.
Driving
74

The braking system of the tow vehicle is rated for operation at the
GVWR not GCWR.
Trailer lamps
Trailer lamps are required on most towed vehicles. Make sure your
trailer lamps conform to local and Federal regulations. See your dealer or
trailer rental agency for proper instructions and equipment for hooking
up trailer lamps.
Using a step bumper
The rear bumper is equipped with an integral hitch and requires only a
ball with a 25.4 mm (one inch) shank diameter. The bumper hasa2270
kg (5 000 lb.) trailer weight and 227 kg (500 lb.) tongue weight
capability.
If it is necessary to relocate the trailer hitch ball position, a
frame-mounted trailer hitch must be installed.
Driving while you tow
Do not drive faster than 88 km/h (55 mph) when towing a trailer. Do not
drive faster than 72 km/h (45 mph) with any weight on the trailer while
towing on a hot day or in hilly country.
Speed control may shut off if you are towing on long, steep grades.
When towing a trailer:
²Use D (Drive) or a lower gear when towing up or down steep hills.
This will eliminate excessive downshifting and upshifting for optimum
fuel economy and transmission cooling.
²Anticipate stops and brake gradually.
When descending long, steep downhill grades, always use a lower gear to
provide engine braking to save wear on brakes. Use Drive (Overdrive
OFF) on moderately steep hills, Second (2) on steep hills, and First (1)
on very steep hills.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to the Severe Duty Schedule in your
ªService Guideº for more information.
Driving
75

Trailer towing tips
²Practice turning, stopping and backing up in an area 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.
²Allow more distance for stopping with a trailer attached.
²The trailer tongue weight should be 10±15% of the loaded trailer
weight.
²After you have traveled 80 km (50 miles), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
²When stopped in traffic for long periods of time in hot weather, place
the gearshift in P (Park) and increase idle speed. This aids engine
cooling and air conditioner efficiency.
²Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer's wheels.
Launching or retrieving a boat
When backing down a ramp during boat launching or retrieval,
²Do not allow the static water level to rise above the bottom edge of
the rear bumper and
²Do not allow waves to break higher than 15 cm (six inches) above the
bottom edge of the rear bumper.
Exceeding these limits may allow water to enter critical vehicle
components, adversely affecting driveability, emissions and reliability.
If the rear axle is submerged in water, the rear axle lubricant should be
changed. Axle lubricant quantities are not to be checked unless a leak is
suspected.
FUEL CONSUMPTION
Fuel economy can be improved by avoiding:
²lack of regular, scheduled maintenance.
²excessive speed.
²rapid acceleration.
²extended idle.
Driving
76

HAZARD LIGHTS CONTROL
Use only in an emergency to warn traffic of vehicle breakdown,
approaching danger, etc. The hazard flashers can be operated when the
ignition is off.
²The hazard lights control is
located on top of the steering
column.
²Depress hazard lights control to
activate all hazard flashers
simultaneously.
²Depress control again to turn the
flashers off.
FUEL PUMP SHUT-OFF SWITCH
If the engine cranks but does not start after a collision, the fuel pump
shut-off switch may have been activated. The shut-off switch is a device
intended to stop the electric fuel pump when your vehicle has been
involved in a substantial jolt.
1. Turn the ignition to the OFF position.
2. Check the fuel system for leaks.
3. If no fuel leak is apparent, reset the fuel pump shut-off switch by
pushing in the button on the switch.
4. Turn the ignition to the ON position. Pause for a few seconds and
return the key to the OFF position.
5. Make a further check for leaks in the fuel system.
