Screeching sound from engine on 'cold' days
Hi All,
I own a 99 civic coupe - has given me flawless service however, since around 2002, it has been emitting a shrill screeching sound when the engine is started cold (such as early in the morning. Once the engine heats up, the sound is gone. I put 'cold' in the subject line because I live in Phoenix AZ :) Yet, this problem occurs more frequently once the weather starts to cool down. I know this is not the brakes, it sounds more like a belt needing some silicon but despite repeated checks with the shop, they cannot find a problem. Any suggestions would be welcome. Thanks, John |

I got new (front) brake pads about 6 mo. ago and had them look at the engine again. Another problem is that this problem occurs when the engine is cold - typically in the mornings. By the time I drive up to the shop, the sound is gone. Then there are periods of days when it disappears completely so makes me suspicious of what's going on. John |

Noise due to loose belts should occur regardless of outside temp, shouldn't it? My car only does that when temperature is <20 degrees F. Annoying as hell but goes away after 1-4 minutes depending on how could it is. |

Re: Screeching sound from engine on 'cold' days
Like Curly said, I would first suspect a belt.
I replaced my alternator belt and removed, then reinstalled the power steering belt earlier this summer (all as part of a bigger job). I immediately started getting the screech-at-cold-startup, too. It turned out I hadn't tightened the alternator belt sufficiently. I did so, and have had no problems since.

Loose belts do this on cold mornings because you have just started the
engine and the Alt goes into a full load to start replenishing the battery.

That's pretty much everything that I would have tried. Nothing harder to find than an intermittent noise or problem. Have you left the vehicle at the dealer overnight, so that they have the first crack at starting it in the morning? Maybe that way, the noise would show itself. -- Brian http://www.cakesbydarlene.ca http://www.accesswave.ca/~orion |

Re: Screeching sound from engine on 'cold' days
My power steering pump makes a whining sound when I start the engine on
real cold mornings (-10 F and below). That noise is different from a slipping belt tough. The whine usually fades away within one or two minutes. Seems that the PS fluid gets thick and the pump cavitates a bit. Carl 90 Integra |

Once the engine is warmed up, squirt some water on one of the belts and restart. If you get the same noise, that's the belt to tighten. You can also try running the fan, headlights, stereo, portable beer fridge, to see if the squeeling lasts longer. Then you could guess it's the alternator belt. I think Honda belts have to be a lot tighter than they did on cars in the 'olden days' 'Curly' |
