How to Remove a Porsche 924 Alternator

Updated February 21, 2017

The alternator in your two-door Porsche 924 coupe helps circulate electricity from your battery to various components, including the radio and headlights. Therefore, if you notice your headlights or interior lights dimming or flickering, you may have to replace your alternator. Other symptoms of a faulty alternator include difficulty starting your car and your radio fading in and out. If you notice these signs, you should take your car to have it tested by a certified technician. Once it's been determined that the problem lies with the alternator, you can tackle the job of removing and eventually replacing it.

Prop open the bonnet of your car and disconnect the negative battery terminal by detaching the terminal cable.

Loosen the tensioner in the engine with the wrench and slip off the belt.

Remove the alternator by loosening the mounting bolt and pulley screw securing it. Take a picture or make note of the configuration of the wiring connected to the alternator to facilitate installing the replacement. Detach the wiring from the alternator.

Pull the alternator housing off by unscrewing the screws and studs holding the housing into place. Tap on the outer rim of the fan with a rubber mallet to separate it from the alternator. Lift the alternator assembly out.
