Engine; Fuel System; Cooling System - Ford Vehicle Owner's Manual

Engine

Start engine every 15 days. Run at fast idle
until it reaches normal operating temperature.
With your foot on the brake, shift through all
the gears while the engine is running.

Fuel system

Fill fuel tank with high-quality unleaded fuel
until the first automatic shutoff of the fuel
pump nozzle.
NOTE: During extended periods of vehicle
storage (60 days or more), fuel may
deteriorate due to oxidation. This can
damage rubber and other polymers in
the fuel system and may also clog
small orifices.
Ford Gas Stabilizer should be added whenever
actual or expected storage periods exceed 60
days. Follow the instructions on the label. The
vehicle should then be operated at idle speed to
circulate the additive throughout the fuel system.
NOTE: Read the 7.3L Diesel Engine Owner
Guide Supplement for information
regarding vehicle storage for your
diesel-powered vehicle.
A volatile corrosion inhibitor added to the fuel
system will protect the fuel system's inner
surfaces from corrosion. Follow the instructions
packaged with the product.

Cooling system

Protect against freezing temperatures.
