Alternator OEM Toyota or Bosch

Bosch is a great aftermarket option.

Yes, if it was from an OEM supplier to Lexus or the auto industry, such as Denso (1/3 owned by Toyota/Lexus), AC Delco, or Bosch, but I would not buy a mystery brand, especially not a rebuilt, because I don't know how much they get rebuilt or tested.

Changed it for another OEM Bosch new (not reman). Subsequent test showed it was now good.

I got BOSCH AL113M from Adv auto (with a code cost me about 80), then went to tractor supply and got several large washers. I took the pulley off my old alt and put it on the new long-nose alt, stacking washers until it lined up.

So my just-installed today reman Bosch SR33X turns the light off with a very slight blip to 1200rpm.

I went with the cheaper Bosch unit myself for my M3, and it's been working well for the past 4k miles.

If the belt was melted to the alternator pulley, there was enough friction to melt the rubber. Simple answer, replace the alternator.

I wasn't crazy with the AC Delco (GM) alternator conversion when I used it on my MGB engine. The Bosch ones seemed to be a little better designed and easier to convert, plus they looked simmilar to the Lucas ones.

Bosch rebuilt alternators are like $175 online. Lots of people experienced low quality rebuilts. Have people had good luck with Bosch rebuilts?

We've had all sorts of problems with Bosch reman alternators. They worked really well until Volvo put the alternator on the CAN network. The reman ones have a ton of trouble making the right charging voltage.
