clicking sound from hybrid side of engine

I recently had the electric hybrid water pump replaced, under warranty. (5 days ago). Tonight coming home I noticed a clicking sound coming from the engine, sounded like a blinker was on, but it wasn't. You could hear it, we were going about 20 mph, on electric. When I pulled into the garage, put it in park but left the engine on, opened the hood, you could still hear it, from the hybrid side of the engine, a clicking sound, at about a blinker rate. Any ideas or reason why? Thanks! I'm at 58K miles and no problems to speak of prior to bringing it in for the recall.

 

Thanks for the note. I see the pump. No clicking today, so far, I checked when the engine was cold, then later after running, but no clicking. I think the clicking was coming from the fuse and relay box though. If it sounds off again - I will pay more closer attention to where the sound is coming from.
