*
[SV09050( ALL)05/95]
In some parts of the country, ªregularº grade
fuels are sold with octane ratings of 86 or even
less, especially in high altitude areas. We
recommend that you do not use these fuels.
Always use a fuel with an octane rating of 87,
even if it is sold as a ªmidgradeº or ªpremium.º

Do not be concerned if your vehicle sometimes
knocks lightly when you drive up a hill or when
you accelerate. However, if a fuel with the
recommended octane rating knocks heavily
under all driving conditions or knocks lightly
driving at cruising speed on level roads, see
your dealer or a qualified service technician.
Persistent, heavy knocking can damage the
engine.

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.
*
[SV19950( ALL)03/95]
NOTE: Do not use an engine coolant that does
not meet all 14 requirements of Ford
Specification ESE-M97B44-A. The use
of an improper coolant may void your
warranty for the engine cooling system.
Use only a premium nationally
recognized brand name engine coolant.
*
[SV19960( ALL)05/95]
Ford Motor Company expressly authorizes the
Ford Rotunda engine coolant recycling process
and chemicals. Use only Ford Rotunda recycled
engine coolant or an equivalent recycled engine

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(B FM)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.
*
[SV21225( ALL)05/94]
5. Reconnect the lower radiator hose and close
the radiator drain cock.
*
[SV21250( ALL)10/94]
Proper procedures for flushing the cooling
system can be found in theTruck Service Manual.
*
[SV21300( ALL)02/95]
Engine coolant refill procedure
*
[SV21400( ALL)10/89]
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.

check engine light, or the temperature warning
light. These sometimes indicate that the emission
system is not working properly.
*
[SV49600( ALL)01/95]
Do not make any unauthorized changes to your
vehicle or engine. Changes that cause more
unburned fuel to reach the exhaust system can
increase the temperature of the engine or
exhaust system.
