You may add water by itself only in an
emergency, but you should replace it with a
50/50 or appropriate mixture as soon as
possible.
*
[SV20200( ALL)01/95]
Have your dealer check the engine cooling
system for leaks if you have to add a quart
(liter) of engine coolant more than once a month.

Checking hoses
*
[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
necessary using Motorcraft parts or their
equivalents.
*
[SV20700( ALL)05/95]
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)06/95]
Proper procedures for flushing the cooling
system can be found in theTruck Service Manual.

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.

NOTE: Use of a transmission fluid other than
specified could result in transmission
malfunction and/or failure. Refer to

Checking the Automatic Transmission
Fluid
*
[SV33701( ALL)05/95]
It is preferable to check the transmission fluid
level at normal operating temperature
150ÊF-170ÊF (66ÊC-77ÊC),after approximately 20
miles (30 km) of driving. However, if necessary,
you can check the fluid level without having to
drive 20 miles (30 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 P (Park)
position, fully set the parking brake and leave
the engine running.
*
[SV33930( ALL)10/89]
RWARNING
Your vehicle should not be driven if the
fluid level is below the bottom hole on
the dipstick and outside temperatures are
above50ÊF (10ÊC).

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.
[SV38150( M)05/94]
3. Then turn the engine off and do not press
the brake pedal.
%*
[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.

*
[SV39400( ALL)02/95]
If you check the power steering fluid when it is
cold, make sure that the fluid reaches the FULL
COLD range on the dipstick. The reading will
only be accurate if the fluid temperature is
approximately 50 to85ÊF (10 to 30ÊC).
*
[SV39405( ALL)06/93]
NOTE: Do not turn the steering wheel of your
vehicle with the engine off. It could
force power steering fluid out from the
reservoir cap or in extreme cases, it
could unseat the cap.

Suspension and Steering
[SV39420( M)06/90]
Modifications
[SV39430( M)06/90]
The suspension and steering systems on your
vehicle have been designed and tested to
provide both safe, predictable performance
whether loaded or empty as well as durable
load carrying capability. Any modifications to
the suspension or steering systems can reduce
your vehicle's performance capability and
adversely affect driver and passenger safety.
Ford recommends that you do not make
modifications such as adding or removing parts
(like lift kits or stabilizer bars) or by using
replacement parts not equivalent to the original
factory equipment.
[SV39440( M)08/90]
RWARNING
The low pressure gas shock absorbers are
charged with nitrogen gas to 90 psi (620
kPa). Do not attempt to heat, puncture or

Readiness for Inspection/Maintenance
Testing
*
[SV51457( ALL)06/95]
In some localities it may become a legal
requirement to pass an
Inspection/Maintenance (I/M) test of the
On-Board Diagnostic (OBD) II system. If the
vehicle's powertrain system or its battery has
just been serviced, the OBD II system is reset to
a ªnot ready for I/M testingº condition. To
prepare for I/M testing, the law specifies a
ªneed for additional mixed city and highway
driving to complete the checkº of the OBD II
system. As soon as all of the OBD II system
checks are successfully completed, the OBD II
system is set to the ready condition. The amount
of driving required to reach the ready condition
varies with individual driving patterns. To
complete this requirement in the minimum
amount of time, refer to the OBD II Drive Cycle
defined below. If the vehicle owner cannot or
does not want to do the additional driving
required by law, a service center can perform
this drive cycle as it would any other type of
repair work.
[SV51458( ALL)05/95]
OBD II Drive Cycle
*
[SV51459( ALL)05/95]
The engine must be warmed up and at
operating temperature before proceeding with
the drive modes of the following OBD II Drive
Cycle.
*
[SV51461( ALL)05/95]
1. Start the engine. Drive or idle (in neutral)
the vehicle for 4 minutes.
[SV51463( ALL)04/95]
2. Idle the vehicle in drive (neutral for manual
transmission) for 40 seconds.
*
[SV51465( ALL)06/95]
3. Accelerate the vehicle to 45 mph (70 km/h)
at 1/4 to 1/2 throttle for 10 seconds.
*
[SV51467( ALL)06/95]
4. Drive the vehicle with a steady throttle at
45 mph (70 km/h) for 30 seconds.
