Replace MFR: BOSCH
note: This is an Internal Fan Bosch Alternator That Fits BMW. There is Be a "Look-A-Like" From Valeo Also (13470). There Was an Original Version of This Unit That Came With the Rear Bottom Mount Unthreaded, While Later Versions (Same OE #) Came With a Threaded Bushing in the Bottom Rear Mount. It is Possible That the Length of the Mounting Bolt May Be Different Between the Two Versions - This is Unknown. The Units Will Interchange Otherwise. A Hex Mounting Bolt (Size M10 x 1.5), Washer, and Nut Could Be Included in the Box With the Unit (If Supplying a Unit Without the Threaded Bottom Bushing) to Replace the Unit With the Threaded Bushing. It Appears That BMW May Have Gone to the Threaded Bushing Because of Heavy Rust Build-Up and Corrosion on the Unthreaded Unit Rear Mounting Area (With Seperate Nut), This is What Rebuilders Report They See on the Cores Being Returned.
