Why is my 2006 Grand Vitara making this noise from the engine

I've had this noise for about a month, not sure where is comes from but it sounds external and seems to be louder

remove the fan belts and PRAY that the noise stops and that it's a worn alternator or water pump. If not, it's internal to the engine and VERY expensive repairs will be needed. Suzukis have very weak engines when that old

Thanks for the quick response Scotty, it turned out it was a little low on oil, I had driven the car 9k miles since the last change, thought it would be all right cause I use best oil available, but it has lost prob like half a qt and because of that it was doing the noise. Anyway oil changed - problem fixed.
