6. Carefully, pull the dipstick out again. If the
oil level is below the ªADD 1 QTº line (3.8L)
or at the ªMINº mark (4.6L), add engine oil
as necessary. If the oil level is beyond the
letter ªFº in full (3.8L) or ªMAXº (4.6L)
mark, engine damage or high oil
consumption may occur and some oil must
be removed from the engine.

Brake Fluid
*
[MC08900( ALL)01/96]
Under normal circumstances, your vehicle
should not use up brake fluid rapidly. However,
expect the level of the brake fluid to slowly fall
as you put more mileage on your vehicle and
the brake lining wears.
[MC09100(M )04/96]
Check the brake fluid at each scheduled engine
oil change or at least once a year. You can do
this by looking at the fluid level in the plastic
reservoir on the master cylinder. Also, see label
on reservoir cap. (To locate the master cylinder,
seeThe Engine Typesin the Index.) The fluid
level should be between the MAX fill mark and
3/8" below the MAX fill line.
*
[MC09200( ALL)01/96]
RWARNING
Brake fluid is toxic.
*
[MC09300( ALL)01/96]
If brake fluid contacts eyes, flush eyes with
running water for 15 minutes. Get medical
attention if irritation persists. If taken internally,
drink water and induce vomiting. Get medical
attention immediately.

[MC09400( ALL)03/96]
If the fluid is low, carefully clean and remove
the filler cap from the reservoir. Fill the
reservoir to the MAX line with Ford High
Performance DOT 3 Brake Fluid C6AZ-19542-AB
or DOT 3 equivalent fluid meeting Ford
specification ESA-M6C25-A.

[MC11600( ALL)02/96]
Use specially formulated windshield washer
fluid rather than plain water, because specially
formulated washer fluids contain additives that
dissolve road grime. For safety reasons, washer
fluids containing an appropriate antifreeze such

(temperatures below32ÊF [0ÊC]).State or local
regulations on Volatile Organic Compounds
(VOCs) may restrict use of the most common
antifreeze, methanol. Washer fluids containing
non-methanol antifreeze agents should be used
only if they provide cold weather protection
without damaging the vehicle's paint finish,
wiper blades, and windshield washer system.

Your vehicle's coolant protects your engine from
overheating in the summer and from freezing in
the winter. Check the level of the coolant at least
once a month. Simply look at the engine coolant
reservoir located in the engine compartment. To
locate the reservoir, see the diagram of your
vehicle's engine underEngine Type, in this
chapter.

[MC12300( ALL)02/96]
The coolant additives also protect the entire
cooling system from internal passageway
corrosion and these additives lubricate the water
pump. The coolant should be serviced as noted
in theMaintenance Schedulebooklet.

[MC15105( 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.
Never increase the engine coolant concentration
above 60%. Leave a 50/50 mixture of engine
coolant and water in your vehicle year-round in
non-extreme climates.
