Vehicle Care 341 Body • Wash vehicle thoroughly to remove dirt, grease, oil, tar or mud from exterior surfaces, rear-wheel housing and underside of front fenders. • Periodically wash vehicles stored in exposed locations. • Touch up raw or primed metal to prevent rust. • Cover chrome and stainless steel parts with a thick coat of auto wax to prevent discoloration. Re-wax as necessary when the vehicle is washed. • Lubricate hood latch, all door latches and trunk lid hinges with a light grade oil. • Cover interior trim to prevent fading. • Keep all rubber parts free from oil and solvents. Engine • The engine oil and filter should be changed prior to storage, as used engine oil contains contaminates that may cause engine damage. • Start the 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 the fuel tank with high-quality fuel until the first automatic shutoff of the fuel pump nozzle. Note: During extended periods of vehicle storage (30 days or more), fuel may deteriorate due to oxidation. Add a quality gas stabilizer product 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. 2013 F-250/350/450/550 (f23) Owners Guide gf, 3rd Printing, December 2012 USA (fus)
