300Tdi Alternators

It's time for a new alternator and I was wondering if there is a reason to buy a particular version other than pulley size and price.

The 300tdi came from a M reg Discovery. The alternator currently fitted has the smaller diameter pulley and is not the original one (no surprise) so I don't know what pulley size was originally fitted.

So far I have learn't:

YLE10113 - Fitted to early 300Tdi engines

AMR4248 - Fitted 94-96 now supersedes to AMR5425

AMR5425 - Fitted 97-98

All 3 are still available.

Looking at Denso, prices vary from £116 for YLE10113 to £162 for AMR4248.

AMR5425 is around £125.

Is there reason to favour AMR5425 over YLE10113?

I can see the the casing is different between the two with AMR5425 looking like it has more vents and would possible cool better.

Does anyone know of any reason to favour one over the other?

Thanks

Mark

I don't often see 300TDI's now,but when I did I was very disappointed with most of the alternators on sale,esp the Denso ones. They seemed to last about a month out of warranty.

Genuine Bosch exchange ones cost a bit more, but did last alot longer.
