Checking the engine coolant
*
[MC11800( ALL)01/96]
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.
*
[MC11850( ALL)01/96]
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.
[MC11900( M)01/96]
Your cooling system is of the coolant recovery
type. The engine coolant recovery reservoir is a
one-piece molded unit. Engine coolant in the
system expands with heat and overflows into the
engine coolant recovery reservoir. When the
system cools down, coolant is drawn back into
the radiator.

[MC12800( ALL)01/96]
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.
*
[MC12850( ALL)01/96]
Add engine coolant only to the coolant
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. Check the engine coolant again
the next few times you drive your vehicle.

*
[MC14000( ALL)01/96]
After you have drained the engine cooling
system:
*
[MC14050( ALL)01/96]
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.
*
[MC14100( ALL)01/96]
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.
*
[MC14150( ALL)01/96]
3. Start and idle the engine until the thermostat
opens and the radiator upper hose becomes
warm.
*
[MC14200( ALL)01/96]
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.
