Do you have to remove the serpentine belt before removing the alternator?
No vehicle is specified, however, in all vehicles I have seen and/or worked on, the serpentine belt must be removed from the pulley that spins the alternator. NOTE: Some vehicles have another, separate, serpentine style belt that runs the a/c compressor and may have to be removed to remove the belt running the alternator. (Complete removal is not necessary unless the belt needs to be replaced.)
Note RADIO CODE before proceeding!!! Disconnect battery Loosen tensioner for the serpentine belt, remove belt. Remove wires affixed to the back of the alternator. Note the wire positions. Remove the 2 bolts holding alternator in place, you may need to remove a brace on the rear of the alternator to the head. Remove alternator. Replacement is the reverse, use the engine decal to reout the serpentine belt properly.
Loosen the serpentine belt by removing one bolt and loosening the other on the belt tensioner located in the top middle of the belt position. Remove the serpentine belt from the alternator. Next remove the 3 bolts holding in the alternator and unplug the wiring harness attached. The alternator should now be able to come free with a little coaxing depending on its condition. Repeat in backwards order when installing a new alternator.
