Hello, Gross. I've been through all three rattles: in the water pump, P/S pump and A/C 
clutch. The first one is easy to test with a stethoscope (a must-have in any tool box. 
Mine was like $4.50 from JCWhitney).

The second and third can be easily diagnosed by removing their respective drive belts.
