Mechman high output alternators · Authorized dealer
The Alero came as a coupe or sedan with either a four-cylinder or a V6, and that engine choice decides which alternator fits. This Oldsmobile Alero high output alternator collection lists four Mechman units: 240 Amp and 320 Amp versions for the 1999-2004 3.4L V6, and 240 Amp and 320 Amp versions for the 2002-2004 2.2L Ecotec.
The Alero's two engines use separate alternator families, and they do not interchange. The 3.4L V6 is covered for 1999-2004, and the 2.2L Ecotec for 2002-2004. Enter your year and engine in the vehicle finder above the products, and the selection narrows to the two Mechman high output alternators for your car.
Many Aleros ended up as first cars and commuter coupes, and they often carry an aftermarket head unit, a compact amplifier and a subwoofer box in the trunk. As these cars age, the original alternator becomes a common failure point. An Oldsmobile Alero high output alternator replaces it and gives a modest system the steady voltage it needs.
The 240 Amp unit suits a single amplifier with upgraded speakers and everyday accessories. The 320 Amp unit makes sense for a larger subwoofer setup, a second amplifier or added lighting. The Alero shares both alternator families with its close relative, the Pontiac Grand Am.
Pair your upgrade with cable from our amp wiring kits, and find other Olds fitments on the Oldsmobile alternators page.
