[SV20600( ALL)10/89]
Inspect all engine and heater system hoses for
deterioration, leaks and loose clamps before
adding or replacing engine coolant. Make
whatever repairs or replacements that are

Engine coolant drain and flush
*
[SV20800( ALL)10/89]
To drain your vehicle's engine coolant:
*
[SV20900( ALL)03/94]
1. Turn off the engine and let it cool. Fully
depressurize the engine cooling system by
covering the radiator cap with a thick cloth
and turning it slowly counterclockwise to the
first stop. Step back while the pressure
releases.
*
[SV20950( ALL)05/90]
2. Remove the cap.
*
[SV21000(B FM)05/90]
3. Attach a small hose to the drain tube at the
bottom of the radiator.
*
[SV21200( ALL)05/90]
4. Let the engine coolant drain into a suitable
container. Disconnect the lower radiator hose
at the radiator connector and drain any
remaining engine coolant into a container.
*
[SV21225( ALL)05/94]
5. Reconnect the lower radiator hose and close
the radiator drain cock.
*
[SV21250( ALL)10/94]

Engine coolant refill procedure
*
[SV21400( ALL)10/89]
After you have drained the engine cooling
system:
*
[SV21500( ALL)01/89]
1. Fill the radiator with a 50/50 mixture of the
specified engine coolant concentrate and
water. Allow several minutes for trapped air
to escape (bubble out) and for engine coolant
to flow through the radiator.
*
[SV21900( ALL)03/94]
2. Replace the radiator cap to its fully installed
position, then back off to the first stop. This
will prevent high pressure from building up
in the cooling system during this part of the
fill procedure.
*
[SV22100( ALL)10/89]
3. Start and idle the engine until the thermostat
opens and the radiator upper hose becomes
warm.
*
[SV22200( ALL)05/95]
4. Shut off the engine and allow the engine to
cool. Cover the radiator cap with a thick
cloth and cautiously remove it. Step back
while the pressure releases.
*
[SV22500( ALL)10/89]
5. Finally, check the radiator and add more
engine coolant if needed, following the
procedures noted above. Reinstall the
radiator cap securely, when finished.
*
[SV22525( ALL)05/90]
6. If more engine coolant is necessary, fill the
overflow reservoir to the appropriate level
marked on the bottle.

If the wiper blades still do not work properly
after you clean them, you may need to replace
the wiper blade assembly or the blade element.
When replacing the wiper blade assembly, blade
refill, or wiper arm always use a Motorcraft part
or equivalent. To replace the blades, follow the
instructions that come with them.

[SV23850(BEF )01/95]
Use specially formulated windshield washer
fluid rather than plain water, because specially
formulated washer fluids contain additives that
dissolve road grime. For safety reasons, washer
fluids containing an appropriate antifreeze such
as methanol should be used in freezing weather
(temperatures below32ÊF [0ÊC]).State or local

Whenever a wheel is removed and then
re-installed, always remove any corrosion that
may be present on the mounting surface of the
wheel and/or the surface of the hub, drum or
rotor that contacts the wheel.
*
[SV26440( ALL)05/95]
RWARNING
Installing wheels without good
metal-to-metal contact at the wheel
mounting surface can cause the wheel lug
nuts to loosen and could allow the wheel
to come off while the vehicle is in motion.

Traction-Lok Rear Axle (If equipped)
*
[SV26460(BEF )03/95]
This axle provides added drive away traction on
slippery surfaces, particularly when one or more
wheels are on a surface with poor traction.
*
[SV26470(BEF )05/95]
RWARNING
To avoid injury, never run the engine
with one wheel off the ground, such as
when changing a tire.

Tire Rotation
*
[SV26600( ALL)03/95]
Because your vehicle's front and rear tires
perform different jobs, they often wear
differently. To make sure your tires wear evenly
and last longer, rotate them at the mileage
shown in theMaintenance Schedule and Record
booklet which came with your vehicle.
*
[SV26700(BEF )07/92]
Rotate the tires according to the following
diagram. If you notice that the tires wear
unevenly, have them checked. If your light truck
has a temporary spare tire, do not include it in
the tire rotation pattern.

Checking the Automatic Transmission
Fluid
*
[SV33701( ALL)02/95]
It is preferable to check the transmission fluid
level at normal operating temperature
150ÊF-170ÊF (66ÊC-77ÊC),after approximately 20
miles (32 km) of driving. However, if necessary,
you can check the fluid level without having to
drive 20 miles (32 km) to obtain a normal
operating temperature if outside temperatures
are above50ÊF (10ÊC).
*
[SV33801( ALL)01/95]
NOTE: If the vehicle has been operated for an
extended period at high speeds or in
city traffic during hot weather, or
pulling a trailer, the vehicle should be
turned off for about 30 minutes to
allow the fluid to cool before checking.
*
[SV33910( ALL)12/91]
With the vehicle on a level surface, start the
engine and move the transmission shift selector
through all of the gear ranges allowing sufficient
time for each position to engage. Securely latch
the transmission shift selector in the Park (P)
position, fully set the parking brake and leave
the engine running.
*
[SV33920(B F )06/94]
NOTE: Vehicles equipped with the 4x4 option
must have the 4x4 shift selector in any
position other than neutral.

Power Steering Fluid

[SV37700( ALL)01/95]
Check the level of the power steering fluid at
least twice a year (i.e., every Spring and Fall).
*
[SV37800( ALL)03/95]
To check the level of your power steering fluid:
*
[SV37900( ALL)02/95]
1. Start the engine and let it run until the
power steering fluid reaches normal
operating temperature. The power steering
fluid will be at the right temperature when
the engine coolant temperature gauge in the
instrument cluster is near the center of the
NORMAL operating temperature range.
*
[SV38000( ALL)01/95]
2. While the engine idles, turn the steering
wheel back and forth several times. Make
sure that the cap assembly is installed at this
time.
*
[SV38100(BEF )05/95]
3. Turn the engine off.
%*
[SV38200( ALL)03/94]
4. Check the fluid level on the dipstick (which
is highlighted in yellow in your vehicle). The
fluid level should be between the arrows in
the FULL HOT range, which is marked on
the side of the dipstick, opposite the side
marked FULL COLD. Do not add fluid if the
level is within the FULL HOT range.

Fuses, Fuse Links and Circuit
Breakers
*
[SV39650(B FM)12/91]
Fuses, circuit breakers and fuse links protect
your vehicle's electrical system from overloading.
If electrical parts in your vehicle are not
working, the system may have been overloaded
and blown a fuse or tripped a circuit breaker.
Before you replace or repair any electrical parts,
check the appropriate fuses or circuit breakers.
*
[SV39700( ALL)10/89]
The following charts tell you which fuses or
circuit breakers protect each electrical part of
your vehicle. If a fuse blows or a circuit breaker
opens a circuit, all the parts of your vehicle that
use that circuit will not work.
*
[SV39800( ALL)02/95]
Once you have determined which fuses or circuit
breakers to check, follow the procedures under
Checking and replacing fusesorChecking and
replacing circuit breakerslater in this chapter.

In general, maintenance, replacement, or service
of the emissions control devices or systems in
your new Ford Motor Company vehicle or
engine may be performed at your expense by
any automotive repair establishment or
individual using automotive parts equivalent to
those which your vehicle or engine was
originally equipped.
*
[SV49300( ALL)05/95]
RWARNING
Do not park, idle, or drive your vehicle in
dry grass or other dry ground cover. The
emission system heats up the engine
compartment and exhaust system, which
can start a fire.
*
[SV49400(BEF )05/95]
RWARNING
On vehicles without original equipment
floor covering or insulation, do not let
passengers ride in your truck in a manner
that allows contact between skin and the
metal floor.
*
[SV49450( ALL)05/95]
If other than Ford or Motorcraft or Ford
authorized remanufactured parts are used for
maintenance, replacement, or for the service of
components affecting emissions control, the
owner should be assured that such parts are
warranted by their manufacturer to be
equivalent to genuine Ford Motor Company
parts in performance and durability. Please
consult your warranty information booklet for
complete warranty information.
*
[SV49500(BEF )05/95]
Watch for fluid leaks, strange odors, smoke, loss
of oil pressure, the charge warning light, the
check engine light, or the temperature warning
light. These sometimes indicate that the emission
system is not working properly.
