[ST07300(BEF )05/95]
A computer system controls the engine's idle
speed. When you start your vehicle, the engine's
idle speed normally runs higher than when it's
warmed up. These faster engine speeds will
make your vehicle move slightly faster than its
normal idle speed. It should, however, slow
down after a short time. If it does not, have the
idle speed checked.
*
[ST07350( ALL)05/95]
If the engine idle speed does not slow down
automatically, do not allow your vehicle to idle
for more than 10 minutes. Have the vehicle
checked.
*
[ST07400( ALL)05/95]
RWARNING
Extended idling at high engine speeds can
produce very high temperatures in the
engine and exhaust system, creating the
risk of fire or other damage.
*
[ST07450( 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.
*
[ST07500(BEF )03/95]
If you consistently start your vehicle in subzero
temperatures, use an engine block heater (if
your vehicle has this option).
%*
[ST07600(BEF )03/95]
Engine Block Heater (If equipped)
(Standard in Canada)
*
[ST07700(BEF )03/95]
Engine block heaters are strongly recommended
if you live in a region where temperatures reach
-10ÊF (-23ÊC) orbelow. An engine block heater
warms the engine coolant, which improves
starting, warms up the engine faster, and allows
the heater-defrost system to respond quickly.

[ST08000(BEF )05/95]
RWARNING
To prevent electrical shock, do not use
your heater with ungrounded electrical
systems or two-pronged (cheater) adapters.
*
[ST08100(BEF )03/95]
For best results, plug the heater in at least three
hours before you start your vehicle. Using the
heater for longer than three hours will not
damage the engine, so you can plug it in at
night to start your vehicle the following
morning.
*
[ST08150(BEF )12/91]
NOTE: Be sure to disconnect the engine block
heater before driving your vehicle.

Fuel Pump Shut-off Switch
*
[ST08190( ALL)03/95]
If the engine cranks but does not start or does
not start after a collision, the fuel pump shut-off
switch may have been triggered. The shut-off
switch is a device intended to stop the fuel
pump when your vehicle has been involved in a
substantial jolt.
*
[ST08200( ALL)03/95]
Once the shut-off switch is triggered, you must
reset the switch by hand before you can start
your vehicle.

terminals.) Most jumper cables have a red
cable and a black cable. The red cable is
generally used for the positive terminals and
the black for the negative ones.

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.
*
[SV20100( ALL)01/95]
Leave the engine coolant in all year. Make sure
that the coolant will not freeze at the
temperature level in which you drive during
winter months. Keep a mixture of engine coolant
in your engine that has a protection rating of at
least-34ÊF (-37ÊC), orwhatever protection rating
is appropriate for the climate in which you live.
*
[SV20125( ALL)03/95]
To find out how much engine coolant mixture
your vehicle's coolant system can hold, seeRefill
capacities for fluidsin the Index.

[SV20151( ALL)01/95]
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.

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.

*
[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.
