It could be the water pump bearing or alternator pulley. Do you hear it while you drive or only makes the noise in idle?

I can hear it at all times.
Its more noticeable when I'm sitting still with no road noise. |

Loosen the belt (by loosening the two alternator bolts) and try rotating the alternator and water pump by hand to see if either is obviously the culprit.

i bet it's the water pump. mine grinded pretty bad when it went at about 75,000 miles. i bought an aftermarket pump for $40 and had local mechanic replace it for $130 labor....much cheaper than the $450-500 toyota quoted me. and i think the oem toyota water pump is crap anyway, so i wanted a different brand. mine was gmb brand.

Hopefully the new waterpump installed under warranty will last longer . 200,000 plus miles would be good . |

Did you check the gonkultor connection? Sometimes if that slips, you will hear a grinding sound when the air is lost in the water collection chamber. If that is in fact the case, you will need to barrow a vacuum stretcher from Autozone. They will require a deposit of course.

The red one is Crashy 2. I rescued her from a deer hit and put her back on the road. Here's her story:

It's deff the water pump, mine made grinding noises when I was at a stand still. Eventually after me ignoring it for a while my belt completely ripped off without me noticing and my car started to overheat, had to replace the water pump did it myself. 80$ for the part, shop wanted to charge 400 -_-

Without looking at how hard it would be access, you could use a long piece of wood rod or something like this as a stethoscope. Hold one end against the various components and the other to your ear. You can do this with the easy ones and eliminate those. Unless you have a real stethoscope. However, You probably could not do this with the water pump due to the location though....just watch out for the moving belt etc.
