My Indy told me to watch my water pump since it was loose but not leaking and I am having that replaced next week when I do the clutch.

lastly you can run the motor without the blef for a short period of time ~1 minute - and listen - if the sound is still there, your problem lies elsewhere

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

After a longish drive last night, I pulled into the garage and heard what sounded like a bad belt. It was not very loud but had that high whine sound just barely audible over the sound of the engine. When I started the car this morning, the sound was gone. Drove it for a few miles and still could not hear it. Ran great. I had the serpentine belt replaced about a year ago. My question is, if a belt is failing, does the sound come and go, or just get worse? Any other thoughts? My Indy told me to watch my water pump since it was loose but not leaking and I am having that replaced next week when I do the clutch. Thanks in advance.

Do you think a failing belt would cause the sound to be intermittent or gradually worsen?

POST 4Original post

My experience is that bearings and belts sound worst at start up in cold weather. Paul

POST 5 / ORIGINAL POSTEROriginal post

Quotes source post: 10115679

Same here. That's why I am a bit puzzled.

POST 6Original post

It's hard to say...which is why I suggested first checking (since it's easy) and second, running with no belt and listening then it's possible its not even your belt/pulley area - could be the clutch throughout bearing or any number of other things...It sounds like you heard it from inside the car, maybe even with the window open...not with your head in the engine compartment.... but I read things into posts how I see fit

POST 7 / ORIGINAL POSTEROriginal post

Definitely heard it inside the car. Immediately turned down the stereo. Was running late so I just shut it off and figured I would deal with it in the morning. No sound to check today, its just purring like a Porsche. I do appreciate the input and the humor! Like Buffett says, "If we couldn't laugh we would all go insane."
