Rep Power: 0 Noise coming from under hood- Help!!
Hi everyone!
I have a 2007 Honda Civic DX-G. I bought it a month ago from a used dealer and since then I've heard this strange noise coming from under the hood. It's a constant noise. Sometimes gets louder but it doesn't increase when accelerating..it's more random.. Took it to a mechanic who at first thought it could be the idler pulley...we changed that..still the same noise! Then he thought it could be the alternator...changed that ..still the same noise
Could it be my engine? Or a different pulley? I'm quite frustrated now and don't really want to spend hundreds of dollars getting it diagnosed at Honda unless I REALLY have to. Hoping someone may have had the same sound coming from their Honda or have heard it before & can give me some answers.
I am planning on taking it to my mechanic next week (who hasn't seen it since he's been away on holidays) but until then I thought I'd post it on here n hopefully get some answers. Obviously I know it is hard to diagnose through description/video but I'm hoping for the best
Thanks in advance

If you think a good mechanic is expensive, try hiring a bad one

How many miles are on the car?
Does the noise go away or change when the AC compressor is running?
Do you have a stethoscope, or similar listening device (long screwdriver or wooden dowel)?
Can you remove the drive belt yourself so pulleys can be inspected?

Re: Noise coming from engine??!! Help!!
not much to go on with that video,
but if i had to take an educated guess i would say its a pulley or belt issue,
a/c pulley, power steering pulley, or something in the timing belt area, water pump, timing belt tensioner, timing belt slapping against the cover?
you need to remove the drive belts one by one and run the engine to see if the noise goes away

It's a single belt drive. Would have to remove the belt, run it for 15 seconds to verify the noise is no longer present, then inspect all the pulleys to find the bad one.
Can't run the engine very long because the belt runs the water pump on this one.
I'd guess the AC pulley is making the noise, but this should be easy to figure out (no guessing).

OP... What type of noise?: Squealing, squeaking, grinding, wobbling, high pitched, low pitched, etc...
Does the noise get worse or change tone when the air conditioner (compressor) is on?
If you still have the old alternator you could tell the mechanic to reinstall it, refund your labor and return the new part for a refund. You shouldn't have to pay for his incorrect diagnosis and guesswork. The tensioner can be spun by hand and alternator with a drill to assimilate load to listen for noises.

Take off the alternator belt and the noise will be gone.
Do not fix it unless gets very bad. I have it like that for the last 8 months. You can install shorter belt bypassing the AC compressor for the months when AC is not needed. I have the belt lenght somewhere. Will post later on.

It's "the engine" fo sho lol
That sounds like a bad bearing on a pulley, but recorded audio can be deceptive sometimes.
Do what ezone said
