Alternator

[at t 2d]

A few months ago I started getting a mystery knock at idle. My mechanic used a stethoscope, but had trouble telling if it was the AC or the alternator. We figured it would become more obvious over time.

I was with our local Pontiac club last weekend and they suggested putting on the headlights and rear defogger to create more of a load and see what happens. The knocking got considerably worse, so the consensus is that the alternator bearings are going bad.

I see that Kirban sells a non-rebuilt alternator for our cars that is only a few dollars more than the rebuilts at the local parts stores. Does anyone have any experience with the one from Kirban?

I got Kirban's on mine ... only driven 225 miles as I put it on when I built my engine recently ... works well ... I also got the later style fan from them as it helps cool it better and also looks a bit cleaner....

It's a Cordon (spelling) unit ...

David, can you confirm the last 6 digits of your VIN is 241118 .... just checking the list I'm working on as I seem to be 1 number off in a number of areas. And did you get your build number from PHS??

Yes, I received the build number from PHS and 241118 is correct.
