Alternator OEM Toyota or Denso

A rebuilt Denso brand alternator will be reliable. Denso box or a Honda box is what I trust, no other brands/savings are worth it.

I worked at a parts place and denso reman is the best. People hear reman and think it’s cheap, but denso is literally the OEM, they take it apart and replace the internals with new ones.

I replaced the my 2010's alternator with a reman denso from RockAuto. Did it myself. Pretty straightforward. I would say a reman denso is better than a new non denso. Some cheap alternators are very unreliable. I've had no issues thus far. It's been about 4 months.

Denso is reputable and quality I doubt you'd run into any issues

I got a denso alternator at Napa for $375-ish. I was a happy pappy

It was a brand new denso and no leaks

I did the alternator recently on my 2013. The price of the part was about the same.

I did the Alternator on my ES350 (same 2GRFE engine) and it sucked. It was my first major repair project and took almost all day for me.

On day two, the Denso overheated and failed, the diodes had burnt out. I replaced it with the stock 70 A Suzuki alternator, which failed the same way on day four.

After buying 4 reman "Dura-CRAP" alternators in less than 3 months... I cut the already bad plug pigtail off a Camry in the JY and bought it and the Denzo Alternator it had, drove the car like that for 2 more years before I parked it.
