Note: During extended periods of vehicle storage (30 days or more),
fuel may deteriorate due to oxidation. Add Motorcraft Gas Stabilizer or
equivalent meeting Ford material specification ESE-M99C112-A to the
vehicle fuel system whenever actual or expected storage periods exceed
30 days. Follow the instructions on the additive label. The vehicle should
then be operated at idle speed to circulate the additive throughout the
fuel system.
Cooling system
• Protect against freezing temperatures.
• When removing vehicle from storage, check coolant fluid level.
Confirm there are no cooling system leaks, and fluid is at the
recommended level.
Battery
• Check and recharge as necessary. Keep connections clean.
• If storing your vehicle for more than 30 days without recharging the
battery, it may be advisable to disconnect the battery cables to ensure
battery charge is maintained for quick starting.
Note: If battery cables are disconnected, it will be necessary to reset
memory features.
Brakes
• Make sure brakes and parking brake are fully released.
Tires
• Maintain recommended air pressure.
Miscellaneous
• Make sure all linkages, cables, levers and pins under vehicle are
covered with grease to prevent rust.
• Move vehicles at least 25 feet (8 m) every 15 days to lubricate
working parts and prevent corrosion.
Removing vehicle from storage
When your vehicle is ready to come out of storage, do the following:
• Wash your vehicle to remove any dirt or grease film build-up on
window surfaces.
• Check windshield wipers for any deterioration.
• Check under the hood for any foreign material that may have collected
during storage (mice/squirrel nests).
