place to buy adjusting pulleys and serpentine belt
 

My car start making weird noices after i changed my alternator. Not sure if runined one of th epulleys or i did not place the belt properly. The belt is chipped and is time for replacement. anyone knows a good and decent price place to get this parts. Thanks

don't mess with aftermarket parts when it comes to this stuff. Spend the extra few bucks more and buy them from the dealership. Shouldn't be that expensive for the adj pulley and belt. Check with Mike from Maranello bmw - he's a sponsor on here.
