How to Remove the Alternator on a Smart Fortwo

Model: Smart Smart 451 - Years 2007-2015
Part: Alternator

Learn how to remove the alternator on a Smart Fortwo. Lift the rear engine cover and secure it, locate the battery and disconnect the terminals (inside the cabin). Use a socket to undo the bolts, taking care not to damage the wiring harness covers, then remove all the alternator mounting bolts (remove the oil sump if you do not want to lower the engine). Once disassembled, extract the alternator from the engine bay. Now take the new replacement part and fit it into the appropriate housing, tighten the mounting bolts, then secure the alternator's side bolts.
