1995 Cadillac De ville 4.9 Signs of a bad water pump

my friend brought this car to me it had a high idle issue but i repaired it. the idle control solenoid had came unplugged.  while the car was running i noticed a loud growling noise with a rattle. i used the old school trick i found a wood dowel or even a long screw driver will work. i started listening to the alternator, then i started listening to the idler and heard the bearings rattling there, on the tension-er pulley i found a light bearing noise, as i started listening to the water pump thats when i heard 90% of the rattle and grinding. this will be a fun job for me to do. ill post other video's of my progress.
