Okay so here's the deal
When I start up my car it still sounds gorgeous but just recently it started sounding like there's a family of birds under my hood..... And yes I checked under the hood and there's no birds. Anyways I already done the following. The thermostat has been changed radiator is new and the only possibility I think it could be is the pulley tensioner? Or the belt. I've never changed these out:( how do I do it?could that even be it

Sounds like the tension pully as you speed up the belt gets tighter there for less bird noise jmo .see if your lights get brighter when you step on the gas it could be affecting your altanator also

All the pulleys are moving, so I don't think that's it. I'm thinking its the belt slipping no?
