Failing Alternator

Failing Alternator
Thanks Tom for suggesting I look more into this. My alternator is failing. 13.3 volts was what it is putting out and not charging the battery very well. Anyway, looking at what others have used. I am leaning towards remanufactured OE Denso. A new Denso is too much.
Lexus of South Atlanta new - $394
Denso reman. - $190.
AC Delco Reman - $160
Local shop to rebuild between $90 - $120

My pleasure Lav. I'm really glad you posted a screen shot in the other thread of your Techstream data regarding water temp - since it also showed the low voltage output of your alternator. At least you'll be able to pre-emptively replace it before it totally fails and possibly strand you somewhere.
Here is my thread on replacing the alternator - DIY if you're so inclined. Definitely get the Denso reman. part # 210-0508. Check Parts.com too but be sure to calculate core shipping charges back as well. I recall that many online places sell the Denso reman without a core charge. Be certain to get an authentic Denso. You are lucky that you have time to shop around and schedule the needed repair at your convenience, not after it completely fails. If you lived closer, I'd install it for you.

There are several on ebay too

and Amazon
The Denso from Amazon has no core charges.

I went ahead and ordered the one from Amazon, same as the link you posted was the one I was looking at. $211 after taxes and expedited shipping. No core charge. Not bad at all.
It's only $80 for the Lexus independent shop to install so I'm probably going to do this route. Not that I don't enjoy saving money but I don't enjoy not having an easy way to work on the car. Street parking, etc...

That video is interesting swfla. I thought about this as well. I will definitely save the old one. I wonder how low the voltage has to drop before I would get some kind of warning from the car. 13.7 is the cut off from what I understand. Why is the car not warning me?

I just called and spoke to a service manager at a Lexus dealer on the West coast. He said the battery light will not come on until the alternator totally fails. Well, there you have it. This is why I am not getting a warning light. Another good reason to monitor some things yourself. Also, waiting for it to totally fail will probably ruin the battery as well costing you an extra $100.

The other odd thing is that years 01 - 04 are one part number and 05 - 06 is another. Both are rated at the same voltage and amperage. I called the Lexus parts department to see if they had an explanation before ordering as I was questioning this considering 04 - 06 are normally grouped together. They did not know but thought it could possibly be a revised mounting specs or something like that.

Glad you got an answer but Lexus's warning upon total failure isn't much help to the consumer, worse than an idiot light
Good thing you're extra careful and double checking things. I try to be that way too.

It's odd. I also was looking at this too. Parts guy at Lexus of South Atlanta did not know what the difference was.

The only physical difference between 210-0570 and the 210-0508 is the electrical plug.
The 0508 has a 3pin connection and the 0570 has a 4pin connection.
I know this because I recently replaced my alternator and was sold the 210-0570 as per the shops recomendation (denso seem to think this is the version needed for an 01), when I needed the 0508.
I did take a picture when I had both alternators in my hands if someone wants a comparison.
