'91 Accord - loud squeaky noise on cold start

    When I start up my '91 Accord in the morning, immediately after I turn the
    key, I notice a loud high frequency sound coming from the engine. The car
    seems to run fine, and this does not happen when I start the car while it's
    warm. If I recall correctly, this seems to start happening after I had my
    timing belt changed a week ago.

    Besides changing the timing belt, recently I also had the oil gasket and
    spark plugs changed.

    Any idea what's going on?

    Thanks for any comment/suggestion.

    By the way, the sound lasts for a very short duration, almost instantaneous.
    After that, the engine seems to run normally.

    It's probably one of your belts. To replace the timing belt you have to
    first remove all the accessory belts and then reinstall them afterwards. If
    they are put on loose, they will usually 'squeal', particularly at start up.

  4. I agree with the intelligent person that told you that the sound is
    probably the result of a belt slipping. It could be the timing belt or one
    of the other belts. You might have a friend start your car while the
    engine is cold. Before the friend starts the car--open the hood and see if
    you can identify which belt is slipping. If you don't notice any belts
    slipping--it's probably the timing belt. Another option is to take it back
    to the mechanic that changed the timing belt--tell him the problem and let
    him fix it for you.

    If it's indeed a loose belt, is this an urgent problem that needs to be
    fixed right away. Does it damage the engine or cause any hazard if I drive
    the car for another week and then take it to the dealer to be fixed? The
    reason I'm asking is because I've made an appointment with the dealer next
    Saturday so I don't need to take time off work to get the car fixed.

    Probably not a critical problem if its just a loose belt.

    Try this: Tomorrow morning when the engine is still cool (and not running),
    reach down in there and try to push in the middle of the longest run on each
    belt. If you can deflect it a half inch or more with about 20 pounds of
    force, its too loose.

    If the belts are all tight, then your problem might be bearing failure in
    one of the pulleys.

    Either way it should run for another week until you get to the dealer.

  7. Which belt is it? If it's not the timing belt, the other belts in most
    cases can be made tighter by loosing the bolts on the item (eg alternator)
    and moving in such a way that it makes the belt tighter. If a friend
    tightens the bolts on the item as you pull it or push it--it's even
    better. Many mechanics have a tool that makes the job easier and does not
    require a fellow mechanic.

    If the timing belt slipped (more than one or two teeth) the engine would
    likely not be running. The noise is probably coming from one of the
    accessory belts, i.e., alternator or power steering. What usually happens
    is that a mechanic will install new belts which then stretch a bit and
    become a little loose since they did not compensate for the stretch during
    the initial installation.
    I agree with that advice. The belts should be adjusted at no charge.
