ALL CHEVROLET DEALERS
With heavy accessory loads and low ambient temperatures, some customers may comment about dim headlights, voltmeter readings in the red region and
batteries being discharged on subject vehicles with the 37 amp alternator.
To reduce these potential conditions, it is not necessary to replace the entire alternator. By changing the stator and rotor with the part numbers listed
below, the alternator output will be that of a 63 amp alternator. If internal components are changed, it should be noted on the outside housing of the
alternator should the alternator need repair in the future.
