screech type sound

[dmercer3]

before I start trying to figure this out myself I want to know if anyone else has already had this issue and solved it.

Basically I get a screech noise from the engine just sometimes. Its usually when Im not accelerating and am at constant speed or cruising.

Its not when Im turning the steering wheel necessarily so I think its not power steering noise.

Its like a screech that almost has a hydraulic or mechanical noise to it.

I have listened under the hood and tried to narrow it down to a specific area but I cant seem to narrow it down that way at all. The belt and pullies look alright but I have yet to take the belt off and spin each pully.

Any advice?

There can be various sources of the screeching sound with the most common being bearing failure in one of the accessory drive pulleys.
Taking the serp belt off and checking everything that spins is the first step in locating the source.

One thing to avoid is "they look alright". Better to prove they are not the culprit.
