recommended oil FORD THUNDERBIRD 2002 11.G Owners Manual

CLEANING LEATHER SEATS (IF EQUIPPED)
All Ford, Lincoln and Mercury vehicles with leather seating surfaces have
a clear, protective coating over the leather.
To clean the leather seats, simply use a soft cloth with Deluxe Leather
and Vinyl Cleaner (F2AZ-19521±WA). Dry the area with a soft cloth.
It is recommended that you use the Deluxe Leather Care Kit
(F8AZ-19G253±AA), available from your authorized Ford, Lincoln or
Mercury dealer. The mild cleaner and special pad available in the kit
cleans the leather and maintains its natural beauty. For best results,
follow the instructions printed on the cleaner label. Regular cleaning of
your leather upholstery helps maintain its resiliency and color.
Do not use household cleaning products, alcohol solutions,
solvents or cleaners intended for rubber, vinyl and plastics, or
oil/petroleum-based leather conditioners. These products may
cause premature wearing of the clear, protective coating.
CLEANING THE INSIDE WINDOWS
Use Ultra Clear Spray Glass Cleaner (E4AZ-19C507±AA) for the inside
windows if they become fogged.
To clean, use two lint-free, soft towels, folded into a pad-shape. Mist the
glass completely with cleaner, and use one of the towels to evenly agitate
the surface. Use the other towel to remove the residue.
CLEANING AND MAINTAINING THE SAFETY BELTS
Clean the safety belts with Extra Strength Upholstery Cleaner
(E8AZ-19523±AA), available from your authorized Ford, Lincoln or
Mercury dealer.
Do not use bleach, dye or any other solvent to clean the belts, as
these actions may weaken the belt webbing.
UNDERBODY
Flush the complete underside of your vehicle frequently. Keep body and
door drain holes free from packed dirt.

Adding engine oil
1. Check the engine oil. For instructions, refer toChecking the engine
oilin this chapter.
2. If the engine oil level is not within the normal range, add only certified
engine oil of the recommended viscosity. Remove the engine oil filler cap
and use a funnel to pour the engine oil into the opening.
3. Recheck the engine oil level. Make sure the oil level is not above the
MAX mark on the engine oil level indicator (dipstick).
4. Install the indicator and ensure it is fully seated.
5. Fully install the engine oil filler cap by turning the filler cap clockwise
tightly until clicks are heard, or until it is snug.
To avoid possible oil loss, DO NOT operate the vehicle with the
engine oil level indicator and/or the engine oil filler cap removed.
Engine oil and filter recommendations
Look for this certification
trademark.
SAE 5W-20 engine oil is recommended.
Only use oils ªCertified For Gasoline Enginesº by the American
Petroleum Institute (API). Use Motorcraft or an equivalent oil meeting
Ford specification WSS-M2C153±H.SAE 5W-20 oil provides optimum
fuel economy and durability performance meeting all
requirements for your vehicle's engine.
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.
Maintenance and specifications

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, start-up
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.
BATTERY
Your vehicle is equipped with a
Motorcraft maintenance-free battery
which is located in the luggage
compartment, next to the spare tire.
Your battery is designed to purge any battery gases to the outside of the
vehicle by means of a vent hose. This vent hose MUST be attached at all
times. Replacement batteries must be of the same vented design.
If your battery has a cover/shield, make sure it is reinstalled
after the battery has been cleaned or replaced.
Your battery normally does not require additional water during its life of
service. For longer, trouble-free operation, keep the top of the battery
clean and dry. Make certain that the vent hose is attached. Also, make
certain the battery cables are always tightly fastened to the battery
terminals.
When the battery is disconnected or a new battery installed, the
transmission must relearn its adaptive strategy. As a result of this, the
transmission may shift firmly. This operation is considered normal and
will not affect function or durability of the transmission. Over time the
adaptive learning process will fully update transmission operation to its
optimum shift feel.

Your vehicle was factory-filled with a 50/50 engine coolant and water
concentration. If the concentration of coolant falls below 40% or above
60%, the engine parts could become damaged or not work properly.A
50±50 mixture of coolant and water provides the following:
²Freeze protection down to -36É C (-34É F).
²Boiling protection up to 129É C (265É F).
²Protection against rust and other forms of corrosion.
²Enables calibrated gauges to work properly.
When the engine is cold, check the
level of the engine coolant in the
reservoir.
²The engine coolant should be at the ªcold fill levelº or within the ªcold
fill rangeº as listed on the engine coolant reservoir (depending upon
application).
²Refer to the Scheduled Maintenance Guide for service interval
schedules.
²Be 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 low or empty. If the reservoir is
low or empty, add engine coolant to the reservoir. Refer toAdding
engine coolantin this chapter.

²Idling for long periods of time (greater than one minute) may waste
fuel.
²Anticipate stopping; slowing down may eliminate the need to stop.
²Sudden or hard accelerations may reduce fuel economy.
²Slow down gradually.
²Driving at reasonable speeds (traveling at 88 km/h [55 mph] uses 15%
less fuel than traveling at 105 km/h [65 mph]).
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 fourth and fifth 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 specificationsin
this chapter.
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).
Maintenance and specifications

Failure to follow these precautions may adversely affect the
handling of the vehicle and make it easier for the driver to lose
control and roll over.
Tires that are larger or smaller than your vehicle's original tires may also
affect the accuracy of your speedometer.
SNOW TIRES AND CHAINS
Driving too fast for conditions creates the possibility of loss of
vehicle control. Driving at very high speeds for extended periods
of time may result in damage to vehicle components.
Snow tires must be the same size and grade as the tires you
currently have on your vehicle.
The tires on your vehicle have all-weather treads that provide traction in
rain or snow.
The use of snow cables is not recommended for this vehicle, as damage
to your vehicle may occur under extreme handling or rough road
conditions. However, if you choose to operate the vehicle with snow
cables, avoid these conditions and follow the manufacturer's
recommendations.
Do not use any type of tire chains, as this will likely cause damage to
your vehicle.
