OK I'm assuming that this is one of the petrol / gasoline engine variants so I'd suggest to first try removing the auxiliary drive belt and turning every pulley and ancillary ( power steering pump , alternator etc) by hand. All should turn easily (with the exception of the AC pump) with no grittyness or wobbly pulleys- If you do find a sticky pump / alternator then it should be replaced or repaired

If the engine is stone cold you can briefly run it with no belts to see if the noise changes or has gone away, this will help show if an ancillary is the issue

then check all the exhaust joints - where the manifold joins the head and the down pipe joints just before the catylst - the best way to do this is to start the engine from cold and feel around each joint with your bare hands - feeling for exhuast gas blowing over your fingers - you'll have about 30 seconds before it all gets too hot
