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.

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

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.

Speedometer
*
[LG12700( ALL)01/95]
The speedometer tells you how many miles
(kilometers) per hour your vehicle is moving.
*
[LG12750(BEF )04/95]
Your vehicle contains a speedometer which
receives its input from the Anti-Lock brake
sensor. The speedometer is also used to provide
a speed signal for correct operation of the
vehicle's Powertrain Control Module (PCM),
electronic transmission, and speed control (if so
equipped). Because of this, it is very
IMPORTANT to change the speedometer's
internal conversion constant if the size of the
tires on the vehicle is changed. Changing the
conversion constant to the proper value when
the tires are changed will also ensure that the
speedometer retains the original factory-set
accuracy. NOTE: The conversion constant can
only be changedsix timesonce the vehicle
leaves the factory. Your Ford dealership service
personnel can change the conversion constant.
*
[LG12753(BEF )01/95]
Some vehicles are equipped with a vehicle speed
(MPH/km/h) limiting device that is contained
within the Powertrain Control Module (PCM).
The purpose of this device is to maintain peak
vehicle speed below a specified limit. (Vehicle
speed limits may vary based on engine
displacement).

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.

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.

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.
