Q: What is the routine preventive maintenance program for the battery in your Ford Expedition?
A: First of all, a regular preventive maintenance program is needed to enable quick and reliable starts of your vehicle's battery. Whenever you are not driving, switch off the engine and accessories as well as disconnect the negative terminal and keep sparks and flames away from the battery. Also, the battery produces flammable hydrogen gas and contains corrosive sulfuric acid, so handle it with care and wear protective glasses. Look for corrosion, cracks, loose connections, clean clamps using warm water or baking soda. Ensure that you check if there are any signs of damage on the terminals before putting them back into place. Use a slow-rate charger to restore a discharged battery following instructions provided.
Q: How do you disconnect the battery on Ford Expedition?
A: To disconnect the battery, first remove both cables, starting with the ground cable to avoid shorting. Remember, the vehicle may need to be driven 10 miles after reconnection for smooth operation. Next, remove the bolt and wedge to lift out the heavy battery, using lifting straps if needed. If necessary, remove the battery tray bolts for component access. Reinstallation is the reverse of removal.
