Alternator Denso or AC DELCO

Ok, so it's a toyota so odds are it's a denso or denso style alternator. I used to rebuild Alternators, you will need access to test certain parts like the regulator, or diode trio, or the windings to see where it's failing.

Personally I’d go with a Denso 27060‑50230. More expensive but it’s an OE part not third party. The one in your car was originally a Denso and it lasted almost 30 years, right?

If and when it does replace it with a denso and enjoy another 200k+ miles of no problems.

Look into a Denso remanufactured alternator. They are the Honda OE brand and are designed to work with Honda's dual-mode charging system. You can find them for under $300 at places like Rockauto or NAPA. I recently replaced mine on a '13 Honda CRV with no issues.

I recently purchased parts from NAPA. Got a Denso reman alternator, water pump, and belt tensioner.

Buy off rockauto and go with denso brand

Alternator is easy. OEM or Denso for sure. It’s a super easy job.

I just did mine last week with Denso remanufactured , snapped the bolt and had to replaced the pulley tensioner too ????

Denso only aftermarket will leave you stranded every couple years. I have went through 2 of them. They both gave a very short warnings before they go.

I used ACDelco on my Hyundai Santa Fe and only lasted 8 months before almost leaving me stranded. Also noticed that aftermarket alternators lugs my engine especially during high output while original genuine alternators do not.
