It's not uncommon for a new belt to require re-tightening soon after it's been replaced. Check the belt for any excessive slack (shouldn't have more than 1/2 -3/4" ). A loose belt would be one possible cause for the loud noise you describe.

Honda Accord metal grinding sound, esp when starting car when cold


A timing belt usually makes a loud squealing noise (like a 'shriek/scream') when it is worn or slipping, not a grinding noise.

A quick check - before you start the car - is to pour some water onto the inside of the belt where it goes around the pulleys. If there's no noise at start up, you know it is the belt at fault (or the metal pulley/s are worn).

There are kits to replace the timing belt (and bearings). Have a look on Ebay:
843results for accord v6 timing belt


If the noise happens before the car moves - it obviously can't be your brakes. When backing up the noise may appear louder simply because your head is turned ..

If the noise is actually coming from a wheel, it possibly could be the backing plate on the brakes - the thin disk behind the brake may be rubbing on the rotor.

However.. a grinding noise ... if it is coming from the front of the engine in the general area of the timing belt be very wary - if a bearing or the belt fails, your engine will be history.

Why not give a mobile mechanic a call? Those guys are usually quite good and a lot cheaper than a workshop

You might check the pulleys that the serpentine belt runs on. Make sure all are free wheeling and not loose or rough or make noise. You would need to remove the belt to check them.

I replaced my starter for a 98 chevy suburban 2 weeks ago. I was hearing a loud clicking noise while starting my truck since then. I took my starter out today because it wouldnt start again. I would just...


Possible not shimmed correctly. The starter teeth have to engage correctly for the starter not to hang up. That's what probably happened & broke teeth off. You had better check your flywheel around the entire circumfrence as teeth may be missing from it as well. Starter won't engage if teeth and flywheel teeth in same spot are broken off. If the flywheel teeth are bad, it will be a spendy fix to put a new one on... Rick

2000 Beetle Loud Whirring at start up


its your secondary air pump. it turns on in the cold morning to inject more air into your exhaust, something about emission. its normal to be high pitched. once on my car it was way loud, i looked and the hose had disconnected. either way its normal if its not super loud. but if its everyone is looking at me loud then check for loose hoses!

Squealing NOISE possibly from fan belt


If the noise going away every time u turning off the ac it's probably your ac compressor belt.however i will suggest to take some vaseline and rub it all over the exposed parts of your drive belt.
