When the engine is cool, add a 50/50 mixture of
engine coolant and water to the engine coolant
recovery reservoir Ð DO NOT ADD DIRECTLY
TO THE RADIATOR. Add straight water only in
an emergency, but you should replace it with a
50/50 mixture of coolant and distilled water as
soon as possible.
*
[MC13115( GV)05/96]
Check the coolant level in the coolant recovery
reservoir the next few times you drive the
vehicle. If necessary, add enough of a 50/50
mixture of coolant and water to bring the liquid
level to the fill line on the reservoir.

[MC13305( GV)05/96]
RWARNING
Never remove the coolant recovery cap
while the engine is running or hot.
*
[MC13405( GV)05/96]
If you must remove the coolant recovery cap,
follow these steps to avoid personal injury:
*
[MC13605( GV)05/96]
1. Before you remove the cap, turn the engine
off and let it cool.
*
[MC13705( GV)05/96]
2. When the engine is cool, wrap a thick cloth
around the cap. Slowly turn cap
counterclockwise to the first stop.
*
[MC13805( GV)05/96]
3. Step back while the pressure releases.
*
[MC13905( GV)05/96]
4. When you are sure that all the pressure has
been released, use the cloth to press the cap
down, turn it counterclockwise, and remove
it.

Use Ford Premium Cooling System Fluid
E2FZ-19549-AA (in Canada, Motorcraft CXC-8-B)
or an equivalent premium engine coolant that
meets Ford specification ESE-M97B44-A. Ford
Premium Engine Coolant is an optimized
formula that will protect all metals and rubber
elastomers used in Ford cooling systems for 4
years or 50,000 miles (80,000 km).

[MC14510( ALL)05/96]
Do not use alcohol or methanol antifreeze or any
engine coolants mixed with alcohol or methanol
antifreeze. Do not use supplemental coolant
additives in your vehicle. These additives may
harm your engine cooling system. The use of an
improper coolant may void the warranty of your
vehicle's engine cooling system.

[MC14605( ALL)05/96]
Recycled engine coolant
*
[MC14705( ALL)05/96]
Ford Motor Company recommends that Ford
and Lincoln-Mercury dealers use recycled engine
coolant produced by Ford-approved processes.
Not all coolant recycling processes produce
coolant which meets Ford specification
ESE-M97B44-A, and use of such coolant may
harm engine and cooling system components.

[MC15010( ALL)05/96]
If you drive in extremely cold climates (less than
-34ÊF [-36ÊC]), it may benecessary to increase
the coolant concentration above 50%. Refer to
the chart on the coolant container to ensure the
coolant concentration in your vehicle is such that
the coolant will not freeze at the temperature
level in which you drive during winter months.

Under normal circumstances, you do not need to
check the fluid level of the transmission, since
your vehicle does not use up transmission fluid.
Refer to theMaintenance Schedulebooklet for
replacement intervals. However, if the
transmission is not working properly Ð for
instance, the transmission may slip or shift
slowly, or you may notice some sign of fluid
leakage Ð the fluid level should be checked.

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).

Because your vehicle's engine is electronically
controlled by a computer, some control
conditions are maintained by power from the
battery. If you ever disconnect the battery or
install a new battery, you must allow the
computer to ªrelearnº its idle conditions before
your vehicle will drive properly. To let the
engine do this, put the gearshift in P (Park), turn
off all the accessories, and start the vehicle. Let
the engine idle for at least one minute. (Engine
must be warm in order to ªlearn.º) Also, allow
approximately 10 miles (16 km) of stop and go
