Hi all, this is my first post on Honda tech forums.
I searched a little and couldn't find an answer. anyway I noticed an annoying wine from my engine (f22b1) and it sound like a belt that's rubbing because its pitch gets higher with engine rpm. it sounds like a super charger this is the closest I could relate to.
I did get my timing belt and balancer belt replaced 2 months ago by a trusted mechanic, the sound didn't start till last week when i was driving on gravel roads trying to find a good fishing spot. I did notice today that the noise seems to only happen when the engines at operating temp. The noise seems to come from the bottom end of the engine, I popped the hood and couldn't really hear it as well as if I was sitting in the drivers seat.

I hope someone can help!

 

timing belts are covered with plastic parts so it is prolly alt belt or a/c belt

if u want u can remove the a/c belt and see is the noise stops. cant drive without alt belt

diagnose from there, maybe give ur mechanic a call
