A brand new Valeo (439317) alternator is $209 on Rockauto and they can be swapped in an hour or two.
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
I then ordered a Valeo from Bimmerworld which arrived seized. Finally ordered the same Valeo from RockAuto (for less money, too) which has been working great so far.
I suggest either getting your OEM DENSO alternator rebuilt at a shop (costs like $60?) or picking up a low mileage used DENSO alternator from a junk yard (or eBay). The Amazon new ones are probably junk and can cause trouble down the line.
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.
