To remove the alternator, start by disconnecting the negative battery cable and then follow specific steps depending on the engine type: For 2.0L Zetec-E engines, remove the coolant expansion tank securing bolt, drivebelt, and power steering reservoir. Unscrew the wiring loom bracket bolt and move the wiring, disconnect the multi-plug, and remove the power steering reservoir bracket bolt. On 2003 and 2004 Zetec-E and Duratec engines, remove the front engine mount bolts, pry the engine forward, and insert one bolt behind the mount to keep the engine in place. Remove the canister purge valve retaining bolts, the plastic cover, and disconnect the wiring from the alternator. Unscrew the alternator mounting bolts, lift the alternator from the engine, and remove the cooling fan and shroud. For 2.0L SPI engines, remove the power steering pipe bracket bolts, exhaust manifold heat shield, drivebelt, and disconnect the wiring from the alternator. Unscrew the alternator mounting bolts and carefully lift the alternator from the engine. For 2.3L and 2005 through 2007 2.0L engines, remove the top alternator heat shield nut from above and the lower one below. Remove the lower engine splash shield, drivebelt, and lower alternator mounting nut. Remove the upper alternator mounting nut and the bolt at the roll-restricting engine mount, then remove the alternator. For 2008 and later models, raise the vehicle and disconnect the small gauge wiring from the alternator. Remove the right driveaxle if necessary. Remove the center support bracket, accessory splash shield, drivebelt, lower alternator air duct, and the large wire from the alternator's B terminal. Remove the alternator mounting nuts, unscrew the alternator mounting studs, and remove the alternator. Regardless of the engine type, ensure you have the correct replacement alternator with matching terminals and identification markings. Installation is the reverse of removal, and make sure to tighten all nuts and bolts to the specified torque settings. Additionally, check whether the new alternator comes with a pulley; if not, you may need to transfer the pulley from the old unit or inquire about pulley installation when purchasing the alternator.
