My car has been making a hissing sound for about 3 months now. What could it be?

Good afternoon,

Where is the noise located? Is it inside or outside the car? Does it do it with the car not moving?

I need as much information as possible to help you.

Can you post a video of the noise so I can hear it. There are so many place the noise can be coming from.

Can you tell us when this does it? Is it only at highway speeds? Do you have to be moving or does it do it sitting still? Does it sound like it is coming from the vents, windows, or engine bay?

Let us know this detail and we can go from there. Thanks

It does it when car is running. I think it might be pulley on water pump.
