2002 Mercury Grand Marquis maintenance

²Five tire rotation (for vehicles
with steel wheels and full size
spare tires)
Replacing the tires
Replace the tires when the wear
band is visible through the tire
treads.
When replacing full size tires, never mix radial bias-belted, or
bias-type tires. Use only the tire sizes that are listed on the
Certification or Tire Label. Make sure that all tires are the same size,
speed rating, and load-carrying capacity. Use only the tire combinations
recommended on the label. If you do not follow these precautions,
your vehicle may not drive properly and safely.
Make sure that all replacement tires are of the same size, type,
load-carrying capacity and tread design (e.g., ªAll Terrainº, etc.),
as originally offered by Ford.
Maintenance and Specifications
228

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
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 to provide traction in
rain and snow. However, in some climates, you may need to use snow
tires and chains.
Follow these guidelines when using snow tires and chains:
²Use only cable type chains offered by Ford as an accessory or
equivalent on vehicles with aluminum wheels. Using SAE class S or
other conventional link type chains may cause damage to the vehicle's
wheel house and/or body. Either cable type chains or SAE class S
chains can be used on vehicles with original equipment steel wheels.
²Install chains securely, verifying that the chains do not touch any
wiring, brake lines or fuel lines.
²Drive cautiously. If you hear the chains rub or bang against your
vehicle, stop and re-tighten the chains. If this does not work, remove
the chains to prevent damage to your vehicle.
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.

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. Police or Handling Package refill
capacity-12.1L (12.8 quarts).
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 1.6-1.8L (3.50-3.75 pints) of rear axle lubricant.
Add 118 ml (4 oz.) of Additive Friction Modifier C8AZ-19B546-A 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.
