How to Remove the Alternator in a Saturn

Save

A faulty alternator in your Saturn can cause a whole host of symptoms. Most of the systems on this car are computer-controlled and require a minimum of 12.7 volts to operate properly.The standard engine package found in a Saturn is the 1.9 liter DOHC motor. The alternator in this vehicle is located low in the engine compartment and, as a result, is a difficult alternator to replace. The average weekend mechanic should be able to complete this repair in about two hours using basic hand tools.

Things You'll Need

  • Wheel chocks
  • Floor jack
  • Jack stands
  • Socket set
  • Wrench set
  • Disconnect the negative battery cable. Position the wheel chocks behind the rear wheels and set the parking brake. Raise the passenger side wheel using the floor jack and position a jack stand under the front sub-frame. Lower the Saturn onto the jack stand. Remove the passenger side front wheel. Remove the passenger side inner-fender splash shield.

  • Remove the serpentine belt by compressing the tensioner, located to the right of the alternator pulley, with a 15 mm wrench and slipping the belt off the alternator pulley. Unplug the electrical connector and unbolt the battery cable found on the back of the alternator.

  • Remove the upper and lower mounting bolts using a 14 mm wrench, socket and ratchet.
