Question could it be the water pump, and a bunch of aditional info

ok this has been the issue for about 8 months now yes it has coolant, oil, transmission fluid, and power steering fluid but as soon as I start it up is makes this almost nails on chalk board worn out bearing sound to every 1/3 a full revolution of one full revolution of the serpentein belt I mean no fluids are running low nore are their any leaks? O yeah and when the thermostat kicks open it acts up more that's why I believe it's it??? and to add to that if I do the water pump swap should I change the thermostat as rule of thumb and porribly I know it's DOHC being the 09 4.0 but only has 64xxx miles on it but the past 10xxx miles have been on and off hard miles, should I change the timing chain but I mean im gonna swap it in one or two years? but they will probably be one or two years of again on and off hard driving, PS I also use royal purpple and k&n filters allong with royal purpple for transmission fluid allong with a new filter 2 miles ago, I know their more lol I only drive it in the summer to fall stored in outside temps but in a gerage.

and when I do this should I automatically replace the idiler pully
