what model BMW? I hope it adds to the story…
I might be remembering incorrectly, but I thought the only water cooled alternators come on V12 7 series.
Exactly what I was hoping for…
Anything with the M62, so 540, 740, X5 from about 99 through 01
Guess I did remember incorrectly 
The Cadillacs with northstar V8s used water cooled alternators too right?
No one cares.
look at my socks!
