1988 FORD BRONCO Owners Manual

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.
*
[SV16500( ALL)04/95]
Change the engine oil and oil filterper the
following, whichever occurs first.

[SV16625( ALL)03/95]
NOTE: Idling the engine for extended periods
will accumulate more hours of use on
your vehicles than is actually indicated
by the mileage odometer.
Consequently, the odometer reading
can be often misleading when
determining the right time to change
your engine oil and filter.
*
[SV16650(BEF )03/95]
If you are using your Ford vehicle in a manner
which allows it to remain stationary while the
engine is running for long periods (door to door
delivery, taxi, police, power/utility company
trucks, or similar duty), then Ford recommends
you increase the frequency of oil and filter
changes to an interval equivalent to 200
ENGINE HOURS of use. Since most vehicles are
not equipped with hourmeters, it may be
necessary for you to approximate your idle time
and plan oil/filter changes accordingly.
*
[SV16800( ALL)04/95]
Refer to theMaintenance Schedule and Record
booklet for additional information.

NOTE: Always dispose of used automotive
fluids in a responsible manner. Follow
your community's standards for
disposing of these types of fluids. Call
your local recycling center to find out
about recycling automotive fluids.

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.

1. Before you remove the cap, turn the engine
off and let it cool. Even when the engine is
cool, be careful when you remove the
radiator cap.
*
[SV18800( ALL)03/95]
2. When the engine is cool, wrap a thick cloth
around the cap and turn it slowly
counterclockwise to the first stop.
*
[SV18900( ALL)03/95]

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.

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
coolant that is certified by the supplier to meet
Ford specification ESE-M97B44-A.

[SV20001( ALL)01/95]
Use Ford Premium Cooling System Fluid or an
equivalent engine coolant that meets Ford
Specification ESE-M97B44-A. Do not use alcohol
or methanol antifreeze and do not use engine
coolant mixed with alcohol or methanol
antifreeze. If you do not use the proper coolant,
the aluminum radiator on your vehicle will
corrode.
*
[SV20100( ALL)01/95]
Leave the engine coolant in all year. Make sure
that the coolant will not freeze at the
temperature level in which you drive during
winter months. Keep a mixture of engine coolant
in your engine that has a protection rating of at
least-34ÊF (-37ÊC), orwhatever protection rating
is appropriate for the climate in which you live.
