Alternator OEM Toyota or AC DELCO

I always get AC Delco from RockAuto... never had one bad out of the box... Can't really speak to any other brands.

I would not cheap out on an alternator, especially if you’re having a shop install it as paying for labor to replace two low quality alternators is equivocal to one OEM.

To date the 4 cylinder Camry alternator is the fastest one I’ve ever replaced. From start to finish I think I spent 20 minutes on it.

only thing I've done is change a battery, an alternator and tires (weather checking).

A 98k on a alternator made after 2020 isn't bad. Almost impressive.

I've been daily driving, road-tripping, and wheeling my 100 from 190k miles to its current 283k. Never once has it left me stranded. In that time I've replaced the alternator

I\u2019ve had an ac delco alternator from rock auto in my Honda Fit for 7 years now.

Radiator let go about 12 months ago, and suspension is well overdue for new bushings. Also recently had to replace an alternator.

I’m having this same issue without the positive results. Brand new alternator battery is good. It does not drive! Turns itself off and says charging system malfunction.

The issue you can run into is most common vehicle alternators are light duty at best. Lets say its a 100 amp alt, don't pull more than 40 amps continuous. A great example is the AC Delco 10si alternator. Loads of cheap knock offs and copies of that alternator all claiming crazy high amperage but none list the duty cycle. The 10si frame is designed for 40 amps of power and the heat that creates. You might be able to get a little more cooling with a better fan but you won't get 100+ amps out of one.
