How to Install an Alternator in a Toyota Diesel Pickup

The alternator in a Toyota diesel pickup is a power generator that powers all the electrical components in the truck. When the alternator dies, the battery won't charge, and the electrical components will start draining the battery down until it, too, finally dies. After you've removed the old alternator, you must know how to properly install the new one.

     Align the mounting holes on the alternator with the mounting bracket on the front of the truck for the alternator.

Make sure that the alternator is oriented so that the electrical plug terminal is facing away from the engine and on the lower half of the alternator.
