Servicing Your Vehicleat the beginning of this chapter.

[SV17700(ALL)08/95]
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 the
Engine Coolant Refill Procedurein this chapter for instructions.
*
[SV17760(ALL)09/95]
RWARNING
Never remove the coolant recovery cap while the engine
is running or hot.
*
[SV17765(ALL)09/95]1.
Before you remove the radiator cap, turn the engine off and
let it cool. Even when the engine is cool, be careful when
you remove the radiator cap.
*
[SV17770(ALL)09/95]2.
When the engine is cool, wrap a thick cloth around the cap
and turn it slowly counterclockwise to the first stop.

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

RWARNING
Be careful not to add engine coolant to the windshield
washer fluid reservoir. If sprayed on the windshield,
engine coolant could make it difficult to see through the
windshield.
[SV20100(ALL)09/95]
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.

Engine Coolant Drain and Flush
*
[SV20800(ALL)10/89]
To drain your vehicle's engine coolant:
*
[SV20900(ALL)03/94]1.
Turn off the engine and let it cool. Fully depressurize the
engine cooling system by covering the radiator cap with a
thick cloth and turning it slowly counterclockwise to the first
stop. Step back while the pressure releases.
*
[SV20950(ALL)05/90]2.
Remove the cap.
*
[SV21000(ALL)05/90]3.
Attach a small hose to the drain tube at the bottom of the
radiator.
*
[SV21200(ALL)05/90]4.
Let the engine coolant drain into a suitable container.
Disconnect the lower radiator hose at the radiator connector
and drain any remaining engine coolant into a container.
*
[SV21250(ALL)05/95]
Proper procedures for flushing the cooling system can be found
in theService Manual.

Engine coolant refill procedure
*
[SV21400(ALL)10/89]
After you have drained the engine cooling system:
[SV21700(ALL)10/89]1.
When cold, fill the radiator to a level 1 to 1 1/2 inches
(38 mm) below the filler neck seat.
*
[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.
*
[SV22200(ALL)05/95]4.
Shut off the engine and allow the engine to cool. Cover the
radiator cap with a thick cloth and cautiously remove it. Step
back while the pressure releases.

Finally, check the radiator and add more engine coolant if
needed, following the procedures noted above. Reinstall the
radiator cap securely, when finished.
*
[SV22525(ALL)05/90]6.
If more engine coolant is necessary, fill the overflow
reservoir to the appropriate level marked on the bottle.
*
[SV22610( X)08/95]
NOTE: Due to air being trapped in the 4.0L engine cooling
system, it is not unusual to experiencea4to7ounce
(120 to 210 ml) coolant loss up to 7,500 miles
(12,000 km) after initial system fill.
*
[SV22620( X)06/95]
In order to bleed the cooling system properly after initial fill
with coolant, it might need up to five cycles of:
*
[SV22630( X)06/95]
n
heating up the system (thermostat open)
*
[SV22640( X)06/95]
n
making sure coolant is at least up to the cold fill mark of
overflow bottle
*
[SV22650( X)06/95]
n
letting the coolant cool down (engine coolant temperature
gauge below the N of NORMAL)
*
[SV22660( X)06/95]
n
topping off the coolant overflow bottle to the cold fill
mark
*
[SV22680( X)06/95]
If coolant loss continues after 7,500 miles (12,000 km), consult
your Ford Dealer.
