Alternator Bosch or Motorcraft

If you were family or my customer I would get the Bosch.

IMO a rebuilt German Bosch unit is far superior to the Chinese alts.

I’m running my a 120amp Bosch but my car is m42 it’s honestly overkill for my setup with aftermarket speakers, amp, and sub.

bosch alternator is better. get a bosch alternator.

Rockauto.com shows reman units, both Bosch and Valeo. As far as interchange with Bosch, I dont know, but worked at the dealer and they always asked if it was Bosch or Veleo because it could not be determined by Vin.

I managed to get a reman Bosch 150a/140a last year from Advance Auto for around $190.

I have replaced my alternator with a good "?" Bosch alternator and it charged for 3 days but now the battery light is on until the motor is above 2500 rpm

Go with an OEM unit by Motorcraft even if it's more expensive. Not somethin you want to do twice, learned this lesson with my Explorer. Threw on an aftermarket unit and it doesn't communicate with Ford's smart charging system correctly so it doesn't provide correct voltages as needed, therefore throwing a charging system warning constantly.

I had a Bosch alternator die in <6 months. Got installed in November 2024 and it died a few weeks ago.

I picked up a 07 jetta 2.5 from the auction for a good deal and only 95k on it. The problem is the battery is not charging, figured ok needs new alternator put a bosch unit in and it is still not charging the battery. Put multi meter to the post on alternator and it is only putting off 11.5v.
