Removing Alternator Procedure
Locating the alternator on the engine won't be a problem. You'll recognize it by the wires that come out of it and by the small fan it has behind the pulley. Once you've located it, proceed with the removing :
- The engine should be cold. You don't want to risk any burns.
- Take the "-" cable of the battery terminal and set it aside to a safe distance, You wouldn't want the cable to accidentally touch the terminal while removing the alternator.
- Loosen the serpentine belt tension-er and take the belt off the alternator pully.
- Remove the wiring on the alternator. If there is a plug, simply pull it out. If the connections are with nuts, remove them with the proper wrench. Remember where the cables go or write it on a peace of paper. (there will usually be two main cables : "B+" that comes from the battery (thicker one) and "D+" that induces the magnetic field in the alternator (thinner one). In any case, remember where which one was, mixing them up can cause damage to the alternator. IMPORTANT: don't apply strong pressure when doing this. Your risking breaking of the connection-screws thus producing major damage.
- The alternator is usually held in two points. The upper on that will have the smaller screw and the lower one that has a longer bolt-screw. First remove the upper one.
- Remove the lower bolt screw. This will usually go a bit harder, so use the rubber head hammer to help the bolt out. In the same time wiggle the alternator a bit, that will also help the bolt coming out.
- Make sure that you have a firm grip of the alternator. You don't want it to fall and cause damage on the engine or on the alternator itself.
- Slowly take the alternator out watching that you don't hook up to anything.
