Fan belt making weird revving up/down sounds.

My car recently started whining- it seems to be the fan belt up front. You can hear the pitch get higher and lower based on how much gas you give it. Is this a sign of a dying belt...or worse?

Thanks!



Probably. Ever replaced the belt? Buy one. Take the old one off. Start the engine (don't run it very long) to check if noise gone. Hope so... Install new belt. Check for the noise again. Still gone? Happy day. Otherwise...

Its not the belt- I think it may be the alternator- thats the direction i'm heading in...the sound is definitely coming from the alternator (or extremely near it).

For future googlers this one turned out to be a failing power steering. Needed replacement. All fixed.
