Grinding Noise from front of engine

Hi there

Car is running GREAT, with one issue (hoping it's not a major one).

Car starts right up - but after warming up, I hear a grinding/rattling noise (kind of like two ball-bearings that don't have sufficient lubrication, being spun around an empty can). The noise is constant after warmup. The car has proper levels of oil, coolant and power-steering fluid.

Here's a link to a video of the car running - you can hear the noise, especially when I get close to the AC unit (AC unit is new, but was added shortly before I bought the car).

https://www.dropbox.com/s/o05qbgfajd...G_2799.MOV.mov

Any help would be much appreciated. Happy Friday!

I had a water pump internal plate come loose and it made that sound, but it came and went if that helps. Check out the clutch fan as well

Re: Grinding Noise from front of engine

Sounds pretty easy to diagnose. Take the belt off or use a long screwdriver up to your ear and place on components until you identify the problem.

x2- remove belts one at a time, see which one make the sound go away.

Re: Grinding Noise from front of engine

Also be sure to turn the AC clutch on and off while it's running. Could be too much slack in the clutch. (at least it isn't the compressor)
