Using the Engine Block Heater (If equipped) Engine block heaters are strongly recommended if you live in a region where temperatures reach -10˚F (-23˚C) or below. An engine block heater warms the engine coolant, which improves starting, warms up the engine faster, and allows the heater-defrost system to respond quickly. To turn the heater on, simply plug it into a grounded 110-volt outlet. Ford recommends that you use a 110-volt circuit that is protected by a ground fault circuit interrupter. RWARNING To prevent electrical shock, do not use your heater with ungrounded electrical systems or two-pronged (cheater) adapters. For best results, plug the heater in at least three hours before you start your vehicle. Using the heater for longer than three hours will not damage the engine, so you can plug it in at night to start your vehicle the following morning. If the Engine Cranks but Does Not Start or Does Not Start After a Collision Fuel Pump Shut-Off Switch If the engine cranks but does not start or does not start after a collision, the fuel pump shut-off switch may have been triggered. The shut-off switch is a device intended to stop the fuel pump when your vehicle has been involved in a major jolt. 51
