    It's probably a fan belt slipping. Check the tension on the belts when the
    engine is cold and let us know which of the belts has the least amount of
    tension on it. You may be able to solve the problem by visiting a auto
    store such as NAPA and buying a spray product that might be named "belt
    dressing" or "belt spray". You could spray it on the belt that is slipping
    and it should make the screeching sound go away. Another way to identify
    the slipping belt is to raise the hood and watch the belts as someone else
    starts the car. Make sure that you don't touch anything under the hood
    while the engine
    is running. Let us know which of the belts is slipping if the belt spray
    does not solve the problem.

    Worn/loose accessory drive belt;fairly easy to replace yourself.
    Not very expensive to have someone replace it for you.

  4. I agree with the other posters that a slipping belt is likely the
    problem. A distant second hypothesis might be a hung up starter
    solenoid. It makes a distinctly different sound that still might be
    called a screech.

    The explanation of why the belt stops screeching after a short time
    (if that is what it is) is that as rubber warms up, it shrinks. (Most
    substances expand when heated. Rubber shrinks).

    I would not advise using belt dressing unless it is an emergency
    situation. Get the belt properly tensioned or replaced.

    The best advice is to adjust or have the belt proper4ly adjusted or
    replaced if needed

    There's only ONE accessory belt,the only other belt is the timing belt,a
    toothed belt;if IT is squealing(and slipping),then the motor would have
    serious problems.
    I suppose it could also be a bad bearing on one of the accessories.
    A temporary "fix" at best.

  7. Yeah, I couldn't agree more about the belt dressing recommendation. It'll
    work in the short term but it's nothing more than a quick-fix, band-aid
    solution. Adjusting the tension would be the proper way to eliminate it.

    Who said there's only one accessory belt? Did the original poster even
    mention what model or year vehicle? My '98 CRV has three accessory belts....
    alternator, PS and AC compressor. I also had to adjust the tension on the
    alternator belt on my '88 Accord last week since it had started to squeal a
    little bit at startup. That car also has three belts(alt/wp, PS, and AC) but
    I no longer use the AC belt since the clutch on the compressor died ten years
    ago.

    Same problem with my 1996 civic (212K km). Although I had a
    maintenance-checked by a dealer in Canada. When I start my car in the
    morning (temperature is around 8 C or less) I hear that screeching
    noise for about a second and it goes as the engine gets started.

    Yes, opening the hood I see several belts (2 or 3) none of them are
    easily accesible, though.
