Hello,

I have noticed that for a few weeks now, my car is making a whistling noise from what I guess is the belt area.... The car only has 45k miles on it and I'm not quite certain it's a belt noise, although maybe it needs to be tightened?? The sound is kind of comes and goes but usually doesn't start until after the car is warmed up. Anyone have any thoughts?

 

Sounds like bearings heating up.

Are you handy at all?

If so, take the accessory belt off and see if it continues. If so, then it is likely inside of the timing cover (tensioner, idler, water pump, etc.)

If not, then it is outside and is the tensioner, ps pump, alternator, AC, idler, etc.

 

Tensioner and bearing for sure
