Engine Coolant Temperature Gauge
*
[LG11201( ALL)03/95]
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.
*
[LG11301( ALL)02/95]
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 indicate at
the top of the Normal band.
*
[LG11401( ALL)05/95]
If, under any circumstances, the pointer moves
above the NORMAL band, the engine coolant is
overheating and continued operation may cause
engine damage.
*
[LG11501( ALL)01/95]
If your engine coolant overheats:
*
[LG11601( ALL)03/95]
1. Pull off the road as soon as it is safely
possible.
*
[LG11701( ALL)03/95]
2. Turn off the engine. If you do not stop the
engine as soon as safely possible, severe
engine damage could result.
*
[LG11801( ALL)05/95]
3. Let the engine cool.DO NOT REMOVE
COOLANT SYSTEM FILL CAP UNTIL
THE ENGINE IS COOL.
*
[LG11901( ALL)04/95]
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.
*
[LG12200( ALL)03/95]

Forced Downshifts
*
[DR11200( ALL)04/95]
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.
*
[DR11235( ALL)03/94]
Power Braking
*
[DR11275( ALL)03/94]
Increasing the engine speed above idle without
vehicle movement (such as holding the brake) in
a forward or reverse gear causes transmission
stall.
*
[DR11285( ALL)03/94]
NOTE: Continued operation in the stall
condition can result in transmission
overheat, malfunction or fluid
expulsion.

[DR11400(B F )03/95]
Using the Clutch
*
[DR11500(B F )01/95]
Make sure the gearshift lever is in the N
(Neutral) position and your right foot is holding
down the brake pedal. Then press the clutch
pedal to the floor with your left foot. Manual
transmission vehicles have a starter interlock
switch. The starter will not crank until the clutch
pedal is fully depressed. Start the engine and
allow it to idle for a few seconds. Move the
gearshift into 1 (First) or R (Reverse).
*
[DR11600(B F )03/91]
To move the vehicle, release the clutch slowly
and at the same time press down slowly on the
accelerator so that the vehicle accelerates.
*
[DR11700(B F )03/95]
Do not drive with your foot resting on the
clutch pedal and do not use the clutch to hold
your vehicle at a standstill while waiting on a
hill. These actions will seriously reduce clutch
life.

214may overheat the engine and transmission,
causing damage to both. In addition, other
vehicle systems and components may also be
damaged.

[DR27975( ALL)05/95]
RWARNING
Do not spin the wheels at over 35 mph
(56 km/h). The tires may fail and injure a
passenger or bystander.
*
[DR28050(BEF )03/95]
Driving With a Heavy Load
*
[DR28101(BEF )01/95]
There are limits to the amount of weight your
vehicle can carry or tow. The total weight of
your vehicle, plus the weight of the passengers
and cargo, should never be more than the Gross
Vehicle Weight Rating (GVWR). Also, the weight
that your vehicle carries over the front axle and
rear axle should never be more than the Gross
Axle Weight Rating (GAWR) for the respective
axle.
*
[DR28150(BEF )01/95]
The weight limits of your vehicle's tires affect
the GVWR or GAWR limitations. Usage of
replacement tires with higher weight limit than
originals does not increase GVWR or GAWR.
Usage of lower capacity replacement tires may
lower GVWR and GAWR limitations.
*
[DR28201(BEF )02/95]
RWARNING
If the GVWR or the GAWR specified on
the Safety Compliance Certification Label
is exceeded, your vehicle may be damaged
or you may lose control and injure
someone.

When turning, drive slightly beyond the normal
turning point so the trailer wheels will clear
curbs or other obstructions.
*
[DR39725(B F )03/95]
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 knob to VENT to stop the
compressor and increase the engine speed for a
short time.
*
[DR39900( ALL)05/90]
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

[DR40000( ALL)11/89]
q
Apply the foot service brakes and hold.
*
[DR40100( ALL)11/89]
q
Have another person place the wheel chocks
under the trailer wheels.
*
[DR40200( ALL)11/89]
q
With the chocks in place, release the foot
service brakes, making sure the chocks are
holding.
*
[DR40300(B F )03/91]
q
For automatic transmissions Ð apply the
parking brake by pressing the service brake
pedal down firmly with your right foot while
applying the parking brake pedal with your
left foot.
*
[DR40400(B F )08/94]

Engine Coolant

[SV17400( ALL)02/95]
Checking the engine coolant
*
[SV17700( ALL)10/89]
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.
*
[SV17750( ALL)03/95]
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.

5. Stand away from the radiator opening. Hot
steam may blow out or hot engine coolant
may even splash out.

[SV19500( ALL)01/93]
Freezing Protection
*
[SV19600( ALL)03/91]
The factory-installed solution of Ford Premium
Cooling System Fluid and water will protect
your vehicle tos35ÊF (s37ÊC).Check the freeze
protection rating of the engine coolant at least
once a year, just before winter.
*
[SV19701( ALL)02/95]
Add engine coolant only to the recovery
reservoir.If the coolant level is low, add to the
reservoir a 50/50 mixture of water and the type
of engine coolant that Ford specifies. You may
add water by itself only in an emergency, but
you should replace it with a 50/50 mixture as
soon as possible.
*
[SV19801( ALL)02/95]
Ford Premium Cooling System Fluid is an
optimized formula that will protect all metals
and rubber elastomers used in Ford engines for
four years or 50,000 miles (80,000 km). It is not
necessary and not recommended to use
supplemental coolant additives in your gasoline
powered vehicle. These additives may harm
your engine cooling system. Follow the
recommended service interval for changing your
engine coolant.
*
[SV19851( ALL)04/94]
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.
