Alternator Denso or OEM Volkswagen

Good job OP. I had the battery light turning on/off for months and figured it was the alternator(newish battery). Was about to purchase a reman Denso for $160, but glad I found a video of Timmy the Toolman on youtube before purchasing and went this route. Pretty easy and straightforward.

Go for a Denso alternator if they have it.

My ‘09 highlander needed one about a year ago around 150k and my local shop put in a reman Denso for way less than a new Denso. Good warranty on it, too.

I believe the OEM for the alternator is Denso. If you can get one of those it’ll probably go another 230k

Get a Denso reman from RockAuto. It is the same as OEM Denso and is <$200 with core return.

Denso if you can find it. It will last another 25 years

Fix that, then replace with a reman Denso alternator from RockAuto.

What sort of alternator are you installing, because I've had two Chinese alternators fail but a genuine denso from pull a part has survived a good thrashing

Purchase a new or remanufactured Denso or TYC alternator. Most others are a roll of the dice in terms of lasting longer than 12months.

I replaced my original alternator (which is also denso out of the factory) with a brand new denso alternator. Should be the exact same thing as the factory alt. It's not working at all. Battery is not staying charged. Had a complete diagnostic done by Honda and they said it is the alt. Kinda disappointed I waisted $700.
