2002 FORD WINDSTAR engine

If other than Ford, Motorcraft or Ford-authorized parts are used for
maintenance replacements or for service of components affecting
emission control, such non-Ford parts should be equivalent to genuine
Ford Motor Company parts in performance and durability.
Do not park, idle, or drive your vehicle in dry grass or other dry
ground cover. The emission system heats up the engine
compartment and exhaust system, which can start a fire.
Illumination of the ªCheck Engineº light, charging system warning light
or the temperature warning light, fluid leaks, strange odors, smoke or
loss of engine power, could indicate that the emission control system is
not working properly.
Exhaust leaks may result in entry of harmful and potentially
lethal fumes into the passenger compartment.
Do not make any unauthorized changes to your vehicle or engine. By
law, vehicle owners and anyone who manufactures, repairs, services,
sells, leases, trades vehicles, or supervises a fleet of vehicles are not
permitted to intentionally remove an emission control device or prevent
it from working. Information about your vehicle's emission system is on
the Vehicle Emission Control Information Decal located on or near the
engine. This decal identifies engine displacement and gives some tune up
specifications.
Please consult yourWarranty Guidefor complete emission warranty
information.
Readiness for Inspection/Maintenance (I/M) testing
In some localities, it may be a legal requirement to pass an I/M test of
the on-board diagnostics system. If your ªCheck Engine/Service Engine
Soonº light is on, refer to the description in theWarning lights and
chimessection of theInstrument Clusterchapter. Your vehicle may not
pass the I/M test with the ªCheck Engine/Service Engine Soonº light on.
If the vehicle's powertrain system or its battery has just been serviced,
the on-board diagnostics system is reset to a ªnot ready for I/M testº
condition. To ready the on-board diagnostics system for I/M testing, a
minimum of 30 minutes of city and highway driving is necessary as
described below:
²First, at least 10 minutes of driving on an expressway or highway.
Maintenance and Specifications
266

²Next, at least 20 minutes driving in stop-and-go, city-type traffic with
at least four idle periods.
Allow the vehicle to sit for at least eight hours without starting the
engine. Then, start the engine and complete the above driving cycle. The
engine must warm up to its normal operating temperature. Once started,
do not turn off the engine until the above driving cycle is complete.
CHECKING AND ADDING POWER STEERING FLUID
²3.8L OHV V6 engine
Check the power steering fluid. Refer to the scheduled maintenance
guide for the service interval schedules. If adding fluid is necessary, use
only MERCONtAT F.
1. Start the engine and let it run until it reaches normal operating
temperature (the engine coolant temperature gauge indicator will be
near the center of the normal area between H and C).
2. While the engine idles, turn the steering wheel left and right several
times.
3. Turn the engine off.

specificationsin this chapter.DOT 3 fluid is recommended.
However, if DOT 3 is not available, DOT 4 fluid can be used.
Brake fluid is toxic. If brake fluid contacts the eyes, flush eyes
with running water for 15 minutes. Seek medical attention if
irritation persists. If taken internally, drink water and induce vomiting.
Seek medical attention immediately.
If you use DOT 5 or any other brake fluid that is not DOT 3 or
DOT 4, 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.
TRANSMISSION FLUID
Checking automatic transmission fluid
Refer to your scheduled maintenance guide for scheduled intervals for
fluid checks and changes. Your transaxle does not consume fluid.
However, the fluid level should be checked if the transaxle is not working
properly, i.e., if the transaxle 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 warmed up
(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.
Maintenance and Specifications

5. Remove the dipstick, wiping it clean with a clean, dry lint free rag. If
necessary, refer toIdentifying components in the engine compartment
in 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 areas for normal operating temperature.
Low fluid level
Do not drive the vehicle if the fluid
level is at the bottom of the dipstick
and the outside temperatures are
above 10ÉC (50ÉF).
Correct fluid level
The transmission fluid should be checked at normal operating
temperatures 66ÉC-77ÉC (150ÉF-170ÉF) on a level surface. The normal
operating temperature can be reached after approximately 30 km
(20 miles) of driving.
The transmission fluid should be in
this range if at normal operating
temperature (66ÉC-77ÉC
[150ÉF-170ÉF]).
High fluid level
Fluid levels above the safe range
may result in transaxle failure. An
overfill condition of transmission
fluid may cause shift and/or
engagement concerns and/or possible damage.
High fluid levels can be caused by an overheating condition.
Adjusting automatic transmission fluid levels
Before adding any fluid, make sure the correct type is used. The type of
fluid used is normally indicated on the dipstick and also in the
Lubricant specificationssection in this chapter.
Use of a non-approved automatic transmission fluid may cause
internal transaxle component damage.
If necessary, add fluid in 250 mL (1/2 pint) increments through the filler
tube until the level is correct.

²If possible, avoid fully loading your vehicle.
²Remove the tire chains when they are no longer needed. Do not use
tire chains on dry roads.
²The suspension insulation and bumpers will help prevent vehicle
damage. Do not remove these components from your vehicle when
using snow tires and chains.
