2000 FORD MUSTANG check engine

If your vehicle is
equipped with a 4.6L
V8 engine,check the
power steering fluid
level with the engine at
ambient temperature.
Allow at least one-half
hour after driving for
the power steering
fluid to cool.
1. Start the engine and
allow the engine to
idle.
2. Turn the steering
wheel left and right
several times.
3. Turn the engine off.
4. Check the fluid level in the reservoir. It should be
between the MIN and MAX lines. Do not add fluid if
the level is within this range.
5. If the fluid is low, add fluid in small amounts,
continuously checking the level until it reaches the
correct operating range. Be sure to put the cap back
on the reservoir.
TRANSMISSION FLUID
Checking automatic transmission fluid
Refer to your Scheduled Maintenance Guide for
scheduled intervals for fluid checks and changes.
Your transmission does not consume fluid. However,
the fluid level should be checked if the transmission
is not working properly, i.e., if the transmission slips
or shifts slowly or if you notice some sign of fluid
leakage.
Automatic transmission fluid expands when warmed.
To obtain an accurate fluid check, drive the vehicle
until it is at normal operating temperature
(approximately 30 km [20 miles]). If your vehicle has

been operated for an extended period at high
speeds, in city traffic during hot weather or pulling a
trailer, the vehicle should be turned off for about 30
minutes to allow fluid to cool before checking.
1. Drive the vehicle 30 km (20 miles) or until it
reaches normal operating temperature.
2. Park the vehicle on a level surface and engage the
parking brake.
3. With the parking brake engaged and your foot on
the brake pedal, start the engine and move the
gearshift lever through all of the gear ranges. Allow
sufficient time for each gear to engage.
4. Latch the gearshift lever in P (Park) and leave the
engine running.
5. Remove the dipstick, wiping it clean with a clean,
dry lint free rag. If necessary, refer toIdentifying
components in the engine compartmentin this
chapter for the location of the dipstick.
6. Install the dipstick making sure it is fully seated in
the filler tube.
7. Remove the dipstick and inspect the fluid level.
The fluid should be in the designated area for
normal operating temperature or ambient
temperature.
Low fluid level
Do not drive the
vehicle if the fluid level
is at the bottom of the
dipstick and the ambient temperature is above 10ÉC
(50ÉF).
Correct fluid level
The transmission fluid should be checked at normal
operating temperature 66ÉC-77ÉC (150ÉF-170ÉF) on
a level surface. The normal operating temperature
can be reached after approximately 30 km (20
miles) of driving.

3. Run the engine until it reaches normal operating
temperature.
4. Allow the engine to idle for at least one minute.
5. Turn the A/C on and allow the engine to idle for
at least one minute.
6. Drive the vehicle to complete the relearning
process.
²The vehicle may need to be driven 16 km (10
miles) or more to relearn the idle and fuel trim
strategy.
²If you do not allow the engine to relearn its
idle trim, the idle quality of your vehicle may
be adversely affected until the idle trim is
eventually relearned.
If the battery has been disconnected or a new
battery has been installed, the clock and the preset
radio stations must be reset once the battery is
reconnected.
²Always dispose of
automotive batteries
in a responsible
manner. Follow your
local authorized
standards for
disposal. Call your
local authorized
recycling center to find out more about recycling
automotive batteries.
WINDSHIELD WIPER BLADES
Check the wiper blades at least twice a year or when
they seem less effective. Substances such as tree sap
and some hot wax treatments used by commercial
car washes reduce the effectiveness of wiper blades.
Checking the wiper blades
If the wiper blades do not wipe properly, clean both
the windshield and wiper blades using undiluted
LEAD

Use the following guidelines to avoid static build-up
when filling an ungrounded fuel container:
²Place approved fuel container on the ground.
²DO NOT fill a fuel container while it is in the
vehicle.
²Keep the fuel pump nozzle in contact with the
fuel container while filling.
²DO NOT use a device that would hold the fuel
pump handle in the fill position.
Fuel Filler Cap
Your fuel tank filler cap has an indexed design with
a 1/8 turn on/off feature.
When fueling your vehicle:
1. Turn the engine off.
2. Carefully turn the filler cap counterclockwise 1/8
of a turn until it stops.
3. Pull to remove the cap from the fuel filler pipe.
4. To install the cap, align the tabs on the cap with
the notches on the filler pipe.
5. Turn the filler cap clockwise 1/8 of a turn until it
stops.
If the ªService Engine Soon/Check Engineº indicator
comes on and stays on when you start the engine,
the fuel filler cap may not be properly installed.
Turn off the engine, remove the fuel filler cap, align
the cap properly and reinstall it.
If you must replace the fuel filler cap, replace
it with a fuel filler cap that is designed for
your vehicle. The customer warranty may be
void for any damage to the fuel tank or fuel
system if the correct genuine Ford or
Motorcraft fuel filler cap is not used.
Maintenance and care

²Revving the engine before turning it off may
reduce fuel economy.
²Using the air conditioner or defroster may reduce
fuel economy.
²You may want to turn off the speed control in
hilly terrain if unnecessary shifting between third
and fourth gear occurs. Unnecessary shifting of
this type could result in reduced fuel economy.
²Warming up a vehicle on cold mornings is not
required and may reduce fuel economy.
²Resting your foot on the brake pedal while driving
may reduce fuel economy.
²Combine errands and minimize stop-and-go
driving.
Maintenance
²Keep tires properly inflated and use only
recommended size.
²Operating a vehicle with the wheels out of
alignment will reduce fuel economy.
²Use recommended engine oil. Refer toLubricant
Specifications.
²Perform all regularly scheduled maintenance
items. Follow the recommended maintenance
schedule and owner maintenance checks found in
your vehicle Scheduled Maintenance Guide.
Conditions
²Heavily loading a vehicle or towing a trailer may
reduce fuel economy at any speed.
²Carrying unnecessary weight may reduce fuel
economy (approximately 0.4 km/L [1 mpg] is lost
for every 180 kg [400 lb] of weight carried).
²Adding certain accessories to your vehicle (for
example bug deflectors, rollbars/light bars,
running boards, ski/luggage racks) may reduce
fuel economy.
