Engine Coolant Temperature Gauge
*
[IS10000( ALL)01/96]
This gauge tells you the temperature of the
engine coolant, not the coolant level. If the
coolant is not at its proper level or mixture, the
gauge indicator will not be accurate.
*
[IS10100( ALL)01/96]
The pointer moves from the C (cold) mark into
the Normal band as the engine coolant warms
up. It is acceptable for the pointer to fluctuate
within the Normal band under normal driving
conditions. Under certain driving conditions,
such as heavy stop and go traffic or driving up
hills in hot weather, the pointer may move to
the top of the Normal band.
*
[IS10200( ALL)01/96]
If, under any circumstances, the pointer moves
above the NORMAL band, the engine coolant is
overheating and continued operation may cause
engine damage.
*
[IS10300( ALL)01/96]
If your engine coolant overheats:
*
[IS10400( ALL)01/96]
1. Pull off the road as soon as it is safely
possible.
*
[IS10500( ALL)01/96]
2. Turn off the engine. If you do not stop the
engine as soon as safely possible, severe
engine damage could result.
*
[IS10600( ALL)01/96]
3. Let the engine cool.DO NOT REMOVE
COOLANT SYSTEM FILL CAP UNTIL
THE ENGINE IS COOL.
*
[IS10700( ALL)01/96]
4. Check the coolant level following the
instructions on checking and adding coolant
to your engine, seeEngine Coolantin the
Index. If you do not follow these
instructions, you or others could be injured.
*
[IS10800( ALL)01/96]

to your engine, seeEngine coolantin the Index. If
you do not follow these instructions, you or

Forced Downshifts
*
[GF08575( ALL)01/96]
To gain extra acceleration injOverdrive or
Drive (O/D OFF), push the accelerator to the
floor. The transmission will automatically
downshift to the appropriate gear: third, second
or first.

Power Braking
*
[GF08625( ALL)01/96]
Increasing the engine speed above idle without
vehicle movement (such as holding the brake) in
a forward or reverse gear causes transmission
stall.
*
[GF08650( ALL)01/96]
NOTE: Continued operation in the stall
condition can result in transmission
overheat, malfunction or fluid
expulsion.

Trailer Towing
*
[GF20770( ALL)01/96]
All vehicles may tow a Class I trailer provided
the Gross Combined Weight (GCW) is less than
or equal to the GVWR shown on the Safety
Compliance Certification Label. For heavier
trailer applications, refer to the towing
information found later in this chapter.
*
[GF20775( ALL)01/96]
Towing a trailer puts additional loads on your
vehicle's engine, transmission, axle, brakes, tires
and suspension. For your safety and for the
good of your vehicle, use the right equipment
for the type of trailer you tow.
*
[GF20785( ALL)01/96]
Your trailer towing capability will vary based on
the standard and optional equipment on your
vehicle. Refer to the followingVehicle
Loading/Towing Informationand the Trailer
Towing Tables to determine the specific towing
capability of your vehicle.

When turning, drive slightly beyond the normal
turning point so the trailer wheels will clear
curbs or other obstructions.
[GF22390( E M)01/96]
When stopped in traffic for long periods of time
in hot weather, place the gearshift selector lever
in P (Park) to increase the engine idle speed.
This aids in engine cooling and air conditioner
efficiency. If the engine overheats, move the
Function Selector Lever to VENT to stop the
compressor and increase the engine speed for a
short time.

[GF22410( ALL)01/96]
Vehicles with trailers should not be parked on a
grade. However, if you must park on a grade,
place wheel chocks under the trailer's wheels as

q
Apply the brake pedal and hold.
*
[GF22430( ALL)01/96]
q
Have another person place the wheel chocks
under the trailer wheels.
*
[GF22440( ALL)01/96]
q
With the chocks in place, release the brake
pedal, making sure the chocks are holding.
[GF22460( E M)01/96]
q
Apply the parking brake by pressing the
brake pedal down firmly with your right foot
while applying the parking brake pedal with
your left foot.
*
[GF22490( E M)01/96]

NOTE: If the transmission is submerged in
water, the fluid should be checked and
changed, if necessary.
*
[GF24340( ALL)01/96]
NOTE: All rear axle lube quantities must be
replaced every 100,000 miles
(160,000 km) or if the axle has been
submerged in water. Otherwise, the
lube should not be checked or changed
unless a leak is suspected or repair
required.

[GF24350( ALL)01/96]
Rocking the vehicle
*
[GF24370( ALL)01/96]
If your vehicle gets stuck (for example, in mud
or snow), you may rock it out of the spot. Shift
in a steady rhythm between forward and reverse
gears. Allow the transmission to fully engage,
then press lightly on the accelerator. Do not rock
the vehicle for more than a few minutes. This
may overheat the engine and transmission,
causing damage to both. In addition, other
vehicle systems and components may also be
damaged.
*
[GF24380( ALL)01/96]
RWARNING
Do not spin the wheels at over 35 mph
(55 km/h). The tires may fail and injure a
passenger or bystander.

Engine Coolant
[MC11750( ALL)01/96]
Checking the engine coolant
*
[MC11800( ALL)01/96]
Your vehicle's engine coolant protects the engine
from overheating in the summer and from
freezing in the winter. Check the level of the
engine coolant at least once a month, but
preferably each time you stop for fuel. Simply
look at the engine coolant recovery reservoir
located in the engine compartment. To locate
this reservoir, see the diagram of your vehicle's
engine underEngine typesin this chapter.
*
[MC11850( ALL)01/96]
If the engine coolant has not been checked for a
long period of time the engine coolant reservoir
may eventually empty. If the engine coolant
reservoir empties, check the engine coolant level
in the radiator. Read the following warnings
before removing the radiator cap. If it is
necessary to fill the radiator, refer to theEngine
Coolant Refill Procedurein this chapter for
instructions.
[MC11900( M)01/96]
Your cooling system is of the coolant recovery
type. The engine coolant recovery reservoir is a
one-piece molded unit. Engine coolant in the
system expands with heat and overflows into the
engine coolant recovery reservoir. When the
system cools down, coolant is drawn back into
the radiator.

NOTE: When you change or add engine
coolant, it is important to maintain
your engine coolant concentration
between 40%(-11ÊF [-24ÊC]) and 60%
(-62ÊF [-52ÊC]),depending on your local
climate conditions. Below 40% you will
lose freeze protection and above 60%
your engine may overheat on a warm
day.

[MC13000( ALL)01/96]
NOTE: Do not use an engine coolant that does
not meet all 14 requirements of Ford
Specification ESE-M97B44-A. The use
of an improper coolant may void your
warranty for the engine cooling system.
Use only a premium nationally
recognized brand name engine coolant.
*
[MC13050( ALL)01/96]
Ford Motor Company expressly authorizes the
Ford Rotunda engine coolant recycling process
and chemicals. Use only Ford Rotunda recycled
engine coolant or an equivalent recycled engine
coolant that is certified by the supplier to meet
Ford specification ESE-M97B44-A.
%*
[MC13100( ALL)01/96]
NOTE: Always dispose of used automotive
fluids in a responsible manner. Follow
your community's standards for
disposing of these types of fluids. Call
your local recycling center to find out
about recycling automotive fluids.
%*
[MC13150( ALL)01/96]
Use Ford Premium Cooling System Fluid or an
equivalent engine coolant that meets Ford
Specification ESE-M97B44-A. Do not use alcohol
or methanol antifreeze and do not use engine
coolant mixed with alcohol or methanol
antifreeze. If you do not use the proper coolant,
the aluminum radiator on your vehicle will
corrode.
