fluid capacity Mercury Grand Marquis 2003 Owner's Manuals

Once through the water, always try the brakes. Wet brakes do not stop
the vehicle as effectively as dry brakes. Drying can be improved by
moving your vehicle slowly while applying light pressure on the brake
pedal.
Driving through deep water where the transmission vent tube is
submerged may allow water into the transmission and cause
internal transmission damage. Have the fluid checked and, if
water is found, replace the fluid.
VEHICLE LOADING
Before loading a vehicle, familiarize yourself with the following terms:
•Base Curb Weight:Weight of the vehicle including any standard
equipment, fluids, lubricants, etc. It does not include occupants or
aftermarket equipment.
•Payload:Combined maximum allowable weight of cargo, occupants
and optional equipment. The payload equals the gross vehicle weight
rating minus base curb weight.
•GVW (Gross Vehicle Weight):Base curb weight plus payload
weight. The GVW is not a limit or a specification.
•GVWR (Gross Vehicle Weight Rating):Maximum permissible total
weight of the base vehicle, occupants, optional equipment and cargo.
The GVWR is specific to each vehicle and is listed on the Safety
Certification Label on the driver’s door pillar.
•GAWR (Gross Axle Weight Rating):Carrying capacity for each axle
system. The GAWR is specific to each vehicle and is listed on the
Safety Certification Label on the driver’s door pillar.
•GCW (Gross Combined Weight):The combined weight of the
towing vehicle (including occupants and cargo) and the loaded trailer.
•GCWR (Gross Combined Weight Rating):Maximum permissible
combined weight of the towing vehicle (including occupants and
cargo) and the loaded trailer.
•Maximum Trailer Weight Rating:Maximum weight of a trailer the
vehicle is permitted to tow. The maximum trailer weight rating is
determined by subtracting the vehicle curb weight for each
engine/transmission combination, any required option weight for trailer
towing and the weight of the driver from the GCWR for the towing
vehicle.
•Maximum Trailer Weight:Maximum weight of a trailer the loaded
vehicle (including occupants and cargo) is permitted to tow. It is

4. When you are sure that all the pressure has been released, use the
cloth to turn it counterclockwise and remove the cap.
5. Fill the coolant reservoir slowly with the proper coolant mixture (see
above), to within the “cold fill range” or the “cold full” level on the
reservoir. If you removed the radiator cap in an overflow system, fill the
radiator until the coolant is visible and radiator is almost full.
6. Replace the cap. Turn until tightly installed. (Cap must be tightly
installed to prevent coolant loss.)
After any coolant has been added, check the coolant concentration, refer
toChecking Engine Coolantsection. If the concentration is not 50/50
(protection to –34° F/–36° C), drain some coolant and adjust the
concentration. It may take several drains and additions to obtain a 50/50
coolant concentration.
Whenever coolant has been added, the coolant level in the coolant
reservoir should be checked the next few times you drive the vehicle. If
necessary, add enough 50/50 concentration of engine coolant and
distilled water to bring the liquid level to the proper level.
If you have to add more than 1.0 liter (1.0 quart) of engine coolant per
month, have your dealer check the engine cooling system. Your cooling
system may have a leak. Operating an engine with a low level of coolant
can result in engine overheating and possible engine damage.
Recycled engine coolant
Ford Motor Company does NOT recommend the use of recycled engine
coolant in vehicles originally equipped with Motorcraft Premium Gold
Engine Coolant since a Ford-approved recycling process is not yet
available.
Used engine coolant should be disposed of in an appropriate
manner. Follow your community’s regulations and standards for recycling
and disposing of automotive fluids.
Coolant refill capacity
To find out how much fluid your vehicle’s cooling system can hold, refer
toRefill capacitiesin this chapter.
Fill your engine coolant reservoir as outlined inAdding engine coolant
in this chapter.

1Use only brake fluids certified to meet Ford specifications. Refer to
Lubricant Specificationsin this chapter. DOT 3 fluid is recommended.
However, if DOT 3 is not available, DOT 4 fluid can be used.
2Ensure the correct automatic transmission fluid is used. MERCONand
MERCONV are not interchangeable. DO NOT MIX MERCONand
MERCONV. Refer to the scheduled maintenance guide to determine
the correct service interval.
3Indicates only approximate dry-fill capacity. Some applications may vary
based on cooler size and if equipped with an in-tank cooler. The amount
of transmission fluid and fluid level should be set by the indication on
the dipstick’s normal operating range.
4Add the coolant type originally equipped in your vehicle.
5Rear axles are considered lubricated for life when the vehicle is used for
normal service. See your scheduled maintenance guide for Severe Duty
requirements.
Traction-Lok axles use 2.1-2.3L (4.50-4.75 pints) of rear axle lubricant.
Add 118 ml (4 oz.) of Additive Friction Modifier XL-3 or equivalent
meeting Ford specification EST-M2C118–A for complete refill of
Traction-Lok rear axle.
Service refill capacities are determined by filling the rear axle 6 mm to
14 mm (1/4 inch to 9/16 inch) below the bottom of the filler hole.
6Use of sythetic or sythetic blend motor oil is not mandatory. Engine oil
need only meet the requirements of Ford specification WSS-M2C153–H
and the API Certification mark.
