Lately the Accord (105k) has a screeching noise when first driven - it
lasts 5 seconds or so and varies with the speed of the car. Then it
goes away. I guess a belt? It's overdue for a general big maintenance
job. I couldn't see anything wrong with the belts. Timing belt was
done about a year and a half back.

I first noticed it when it was raining out, but now it does it when
it's dry. Not all the time, maybe half the time.

Any suggestions appreciated.
