1999 FORD F150 service schedule

BRAKES
Your service brakes are self-adjusting. Refer to the scheduled
maintenance guide for scheduled maintenance.
Occasional brake noise is normal and often does not indicate a
performance concern with the vehicle's brake system. In normal
operation, automotive brake systems may emit occasional or intermittent
squeal or groan noises when the brakes are applied. Such noises are
usually heard during the first few brake applications in the morning;
however, they may be heard at any time while braking and can be
aggravated by environmental conditions such as cold, heat, moisture,
road dust, salt or mud. If a ªmetal-to-metal,º ªcontinuous grindingº or
ªcontinuous squealº sound is present while braking, the brake linings
may be worn-out and should be inspected by a qualified service
technician.
Anti-lock brake system (ABS) (if equipped)
On vehicles equipped with an anti-lock braking system (ABS), a noise
from the hydraulic pump motor and pulsation in the pedal may be
observed during ABS braking events. Pedal pulsation coupled with noise
while braking under panic conditions or on loose gravel, bumps, wet or
snowy roads is normal and indicates proper functioning of the vehicle's
anti-lock brake system. The ABS performs a self-check at 17 km/h (10
mph) after you start the engine and begin to drive away. A brief
mechanical noise may be heard during this test. This is normal. If a
malfunction is found, the ABS warning light will come on. If the vehicle
has continuous vibration or shudder in the steering wheel while braking,
the vehicle should be inspected by a qualified service technician.
The ABS operates by detecting the
onset of wheel lockup during brake
applications and compensating for
this tendency. The wheels are
prevented from locking even when
the brakes are firmly applied. The
accompanying illustration depicts
the advantage of an ABS equipped
vehicle (on bottom) to a non-ABS
equipped vehicle (on top) during
hard braking with loss of front braking traction.

When towing a trailer:
²Use a lower gear when towing up or down steep hills. This will
eliminate excessive downshifting and upshifting for optimum fuel
economy and transmission cooling.
²Anticipate stops and brake gradually.
Exceeding the GCWR rating may cause internal transmission
damage and void your warranty coverage.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to your Scheduled Maintenance guide
for more information.
Trailer towing tips
²Practice turning, stopping and backing up in an area before starting on
a trip to get the feel of the vehicle trailer combination. When turning,
make wider turns so the trailer wheels will clear curbs and other
obstacles.
²Allow more distance for stopping with a trailer attached.
²The trailer tongue weight should be 10±15% of the loaded trailer
weight.
²After you have traveled 80 km (50 miles), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
²When stopped in traffic for long periods of time in hot weather, place
the gearshift in P (Park) (automatic transmissions) or N (Neutral)
(manual transmissions). This aids engine cooling and air conditioner
efficiency.
²Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer's wheels.
Launching or retrieving a boat
When backing down a ramp during boat launching or retrieval,
²Do not allow the static water level to rise above the bottom edge of
the rear bumper and
²Do not allow waves to break higher than 15 cm (six inches) above the
bottom edge of the rear bumper.

Engine oil and filter recommendations
Look for this certification mark.
Ford oil specification is WSS-M2C153-G.
Use SAE 5W-30 motor oil certified for gasoline engines by the American
Petroleum Institute.
Do not use supplemental engine oil additives, oil treatments or engine
treatments. They are unnecessary and could, under certain conditions,
lead to engine damage which is not covered by your warranty.
Change your engine oil and filter according to the appropriate schedule
listed in the Scheduled Maintenance Guide.
Ford production and aftermarket (Motorcraft) oil filters are designed for
added engine protection and long life. If a replacement oil filter is used
that does not meet Ford material and design specifications, startup
engine noises or knock may be experienced.
It is recommended you use the appropriate Motorcraft oil filter (or
another brand meeting Ford specifications) for your engine application.
BRAKE FLUID
Checking and adding brake fluid
Brake fluid should be checked and
refilled as needed. Refer to the
Scheduled Maintenance Guide for
the service interval schedules:
1. Clean the reservoir cap before
removal to prevent dirt or water
from entering the reservoir.
Maintenance and care
174

2. Visually inspect the fluid level.
3. If necessary, add brake fluid until
the level reaches MAX. Do not fill
above this line.
4. Use only a DOT 3 brake fluid
certified to meet Ford specifications.
Refer toLubricant specificationsin theCapacities and specifications
chapter.
Brake fluid is toxic.
If you use a brake fluid that is not DOT 3, you will cause
permanent damage to your brakes.
Do not let the fluid level in the reservoir for the master cylinder
fall below the MIN mark. If master cylinder runs dry, this may
cause the brakes to fail.
CLUTCH FLUID (IF EQUIPPED)
Check the clutch fluid level. Refer to the Scheduled Maintenance Guide
for the service interval schedules.
During normal operation, the fluid level in the clutch reservoir should
remain constant. If the fluid level drops, maintain the fluid level at the

ENGINE COOLANT
Check the level of the engine
coolant in the reservoir. Refer to the
Scheduled Maintenance Guide for
service interval schedules. Be sure
to read and understandPrecautions
when servicing your vehiclein
this chapter.
If the engine coolant has not been checked at the recommended interval,
the engine coolant reservoir may become empty. If this occurs, add
engine coolant to the reservoir. For more information on engine coolant
maintenance, refer toAdding engine coolantin this chapter.
Automotive fluids are not interchangeable; do not use engine coolant,
antifreeze or windshield washer fluid outside of its specified function and
vehicle location.
Adding engine coolant
Do not put engine coolant in the reservoir for the windshield
washer fluid.
Do not mix conventional green coolant, orange coolant or
recycled coolants together in your vehicle. Use only the type of
coolant with which your vehicle was originally equipped. If you
are unsure which type of coolant your vehicle requires, contact
your local dealer.
If sprayed on the windshield, engine coolant could make it difficult to see
through the windshield.
When the engine is cool, add a 50/50 mixture of engine coolant and
water to the engine coolant reservoir. Add straight water only in an
COLD FILL
RANGE
