I have seen dealer remanufactured part doa and also fail after use. Just because the part costs more does not mean it is better quality. Denso has a where to buy because they know oem parts are used in the refurb process. Going brand new oem is the way to go if money is not a problem to make sure the part will last.

 

I have one on the shelf i was saving for our LS. As the car was totalled, was planning on putting on ebay. I can check the part number and let you know later if interested. It is a Denso part new in box.

 

Exception to every rule but buying OE parts overwhelming means better and of course higher cost.

 

I wonder if a new, high output alternator for systems would hold up just as long as a new oem

 

The one i have on the shelf is denso 210-0570. New reman denso.

 

Removed the alternator yesterday. Couple things I would like to share:
1. I think the hardest part for me was to unplug the connector. As the car aged, the plastic was hard and difficult to leverage the push/pull action on the tab. I used the F word a few times
2. One of the "bolt" didn't get lose. The whole stud came out. (see pic). That took a bit of my time.
Right after I got the alternator out, I checked online price from Lexus which was about $270. I called my local Lexus and they wouldn't honor the price. The part manager told me they are not part of "Lexus online part". He wanted $500 for the alternator. So I ended up ordering from Lexus and alternator is on the way (shipping out from Lexus of Portland).

 

Just got the part from Lexus.
Noticed there are no nut for the positive connector so I will reuse the old one.
