292 [SV13745( ALL)02/95]Synthetic engine oils which are CERTIFIED and
of the preferred viscosity may be used in your
engine. The engine oil and oil filter must still be
changed according to the maintenance schedule.

Checking and Adding Engine Oil
*
[SV13800( ALL)03/95]
Since the proper amount of engine oil is
important for safe engine operation, check the oil
using the dipstick each time you put fuel in
your vehicle. Remember the engine must be off,
the oil must be warm and the vehicle must be
parked on level ground.
*
[SV13900( ALL)03/95]
Checking the engine oil level:
*
[SV14000( ALL)02/95]
1. Turn the engine off after it has warmed up
and allow a few minutes for the engine oil
to drain back into the oil pan.
*
[SV14050(B F )03/95]
2. Set the parking brake, making sure that the
gearshift is securely latched in P (Park)
(automatic transmission) or 1 (First) (manual
transmission).
*
[SV14100( ALL)02/95]
3. Open the hood. Protect yourself from engine
heat.
*
[SV14200( ALL)03/95]
4. Locate the engine oil dipstick (highlighted in
yellow) and carefully pull it out of the
engine.
*
[SV14300( ALL)01/95]
5. Wipe the dipstick clean and put it back into
position, making sure it is fully seated.

6. Carefully, pull the dipstick out again. If the
oil level is below the ªADD 1 QT.º line, add
engine oil as necessary. If the oil level is
beyond the letter ªFº in FULL, engine
damage or high oil consumption may occur
and some oil must be removed from the
engine.
*
[SV14600( ALL)01/95]
7. Put the dipstick back in and make sure it is
fully seated.
*
[SV14800( ALL)01/95]
It may be necessary to add some oil between oil
changes. Make sure you use a CERTIFIED
engine oil of the preferred viscosity. Your
vehicle's warranty coverage may not apply if
engine damage is caused by the use of improper
engine oil.
*
[SV15000( ALL)03/95]
Add engine oil through the oil filler cap
highlighted in yellow. To add oil, remove the
filler cap and use a funnel to pour oil into the
opening. Be careful not to overfill the engine.
Recheck the oil level after you finish adding oil.

Engine Coolant
*
[SV17400( ALL)02/95]
Checking the engine coolant
*
[SV17700( ALL)10/89]
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 theEngine
Coolant Refill Procedurein this chapter for
instructions.

Freezing Protection
*
[SV19600( ALL)03/91]
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.
*
[SV19701( ALL)02/95]
Add engine coolant only to the recovery
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.
*
[SV19801( ALL)02/95]
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.

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]

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.
*
[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.
*
[SV22500( ALL)10/89]
5. 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.

Whenever a wheel is removed and then
re-installed, always remove any corrosion that
may be present on the mounting surface of the
wheel and/or the surface of the hub, drum or
rotor that contacts the wheel.

Tire Rotation
*
[SV26600( ALL)03/95]
Because your vehicle's front and rear tires
perform different jobs, they often wear
differently. To make sure your tires wear evenly
and last longer, rotate them at the mileage
shown in theMaintenance Schedule and Record
booklet which came with your vehicle.
*
[SV26700(BEF )07/92]
Rotate the tires according to the following
diagram. If you notice that the tires wear
unevenly, have them checked. If your light truck
has a temporary spare tire, do not include it in
the tire rotation pattern.

It is preferable to check the transmission fluid
level at normal operating temperature
150ÊF-170ÊF (66ÊC-77ÊC),after approximately 20
miles (32 km) of driving. However, if necessary,
you can check the fluid level without having to

operating temperature if outside temperatures
are above50ÊF (10ÊC).
*
[SV33801( ALL)01/95]
NOTE: If the vehicle has been operated for an
extended period at high speeds or in
city traffic during hot weather, or
pulling a trailer, the vehicle should be
turned off for about 30 minutes to
allow the fluid to cool before checking.

fluid will be at the right temperature when
the engine coolant temperature gauge in the
instrument cluster is near the center of the
NORMAL operating temperature range.
