:banghead:Hey guys,

My alternator just died and I would like to know which one I should buy(2001 325i). A 120 Amp or a 150 amp one? What is the stock amp number?Your help will definitely be appreciated.

Thanks in Advance!

Look at the manufacturer label to see the amp. Use a mirror if you have to as shown.

Also you could also replace the voltage regulator which is cheaper than the whole alternator assuming it is the voltage regulator that is bad. Otherwise get the whole alternator replacement.
