DENSO Alternator Replacement Brushes, #SA8201
Our experience shows that you can usually replace the brushes in these alternators once, usually around 100K miles. The second time the alternator should be rebuilt or replaced because the slip ring (where the brushes rub) may be too worn. Your mileage may vary of course. In 1999 and in 1989 model years one of two alternators were supplied. These brushes only fit the Nippon Denso alternator. If you have the Chrysler alternator these will not fit. Please be sure your alternator in a Denso before ordering.
