#620, "RE: Mine was the water pump" In response to In response to 9
as long as the noise doesn't get louder as the rpm increases you don't have anything to really worry about. I know the sound your talking about it's coming from somewhere around the condenser. Any kind of knock would sound like it's right on top of the engine and would get louder as the engine revs, and sounds more like a rattle than a constant click, click,click...
