Hi SMEs,

My 2003 Honda civic sedan has started making rattling noise at low RPMs and goes away when I go above certain RPM (2~2.5K rpm).
Earlier I used to get this rattling noise only during cold starts @ low RPMs and used to go away after 2-3 minutes.
I think noise is originating from near alternator (near the belt) and sounds like a metal piece vibrating/hitting another metal piece/gear.

Any pointers to resolve this will be of great help.

cheers,
Rocky

 

SOLVED!
it was a loose bolt that holds the alternator, not very easy to identify as its below the power steering pump.
