ACDelco Alternators with Limited Lifetime Warranty
ACDelco remanufactured alternators are available for most vehicles on the road today and are 100 percent tested after remanufacture.
Rectifiers
Rectifier failure, most often caused by diode malfunction, is one of the primary causes of alternator failure.
ACDelco Rectifiers are 100 percent electronically tested and replaced when needed.
Bearings
Bearings are critical to alternator durability because of extreme lateral loads applied by the drive belt, in addition to excessive heat and vibration.
Bearings are always replaced.
ACDelco Alternators use only quality bearings with high-temperature lubrication and double-lipped rubber seals.
Rotors and Stators
The heart of the alternator and its current-generating components, rotors, and stators may be subjected to excessive heat that can deteriorate insulation and cause shorts.
ACDelco Rotors and Stators are electronically tested for proper performance then sealed with a flexible secondary insulating coating.
Slip Rings
Slip rings must be in constant contact with the brushes, or uneven wear can occur and lead to failure.
ACDelco Slip Rings are precision-polished to help maximize electrical contact and consistent output.
Brushes
Worn brushes interrupt electrical contact and shorten the life of alternators.
Brushes are always replaced.
ACDelco Brushes are 100 percent lead-free and durability-tested for performance and reliability.
