Alternator OEM FORD or Bosch

I would go Bosch if I had the option. Mine went out on a road trip. I had to go with what option was available at the auto store I was able to limp to. Lucky there was one close by but it was who knows what brand. It was my only option so I bought it. Probably duralast or something but it’s working 2 years later.

I had a car get flooded for 6 months and the Bosh alternator still worked perfectly for another 21 years. Would buy again

Fcp euro has an 100amp bosch one that works well. They have a lifetime warranty too.

Funny enough, I just did this dance today! Found a nearly new looking Bosch unit that someone had already kindly removed from the wrecker's car for me. Got it installed and tested exactly like yours though, so I'm happy.

imo take it back and grab a new Bosch from FCPEuro - https://www.fcpeuro.com/products/volvo-alternator-bosch-al157x

There is a Bosch unit that will fit with the same connectors, but the pulley is usually different. I went to a local auto electric shop and they asked about the current I wanted at what revs and they built a Bosch unit with the appropriate coils and fitted my old pulley. Plug and play, and it's been flawless for 10 years or more.

Even brand name remans like Bosch and denso are suspect but generally much less so.

- Alternator is intermittent

- Rear bushes are audibly fucked

- Radiator fan packed up so it overheats when idling in warm weather

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.

I recently had two brand new Bosch remanufactured alternators fail. One after six weeks, and one was bad right out of the box.
