Alternator OEM FORD or Denso

DIY Guy here, I always use Denso parts for my Hondas when it comes to electrical stuff. Denso is the OEM parts supplier for Honda's alternators. I just replaced an alternator in my sister's 2011 Acura RDX with a remanufactured Denso unit and she's had no problems with it at all.

That mechanic must be using some really cheap alternators, we use denso alternators where I work and rarely have issues.

Don\u2019t get any of those aftermarket ones. I\u2019m not sure what aftermarket brand it was that my mechanic got but months later the steering wheel would intermittently lock up while driving. It was not easy to diagnose as the voltage would read fine. Ended up getting a Denso one, paid a lot because needed it urgently. Been fine ever since.

Yes, get a Denso reman from RockAuto for less than $200 after core.

Get the Suzuki Grant Vitara V6 105a by Denso. Bolts on and looks just like factory. Goes from lame 70a on the early t4r's to a 105a with this upgrade. Runs my stereo and accessories like it's nothing.

I went with a Denso reman and it’s been holding up fine for 12k miles.

If it is an original Denso, the best unit to use is the one that you have. It likely can be serviced with new brushes, rectifier, whatever. Do NOT use an original Denso as core for a cheap reman. A puppy dies every time someone does that. Those remans just do not last.

Same at Firestone... 1697 for all quoted with denso alternator. The location/labor is what gets you on this one.

The alternator of my Corolla died. I bought a reman Denso alternator from RockAuto and made the swap. However, the new alternator makes a loud, screeching sound when I start the car. It goes away after a minute-ish.

My neighbor had a Ford mustang and he had to jump start it about once a week. I checked the alternator and it had power when the car was off. Bad diode.
