It doesn't sound like a water pump-type noise. If it is from this area, you may want to locate the noise source by safely supporting the right-front of the car and removing the splash shield. You can then listen and locate the noise better. Diagnose first.

The evaporative vapor purge solenoid also pulses a duty-cycle and may be heard at some times and not others. You can feel the 'heartbeat' by placing your fingers on it while hearing the noise. This is often confused with a lifter noise. Locate it with your underhood vacuum map.
