    One of the maintenance issues necessary when I bought Black Top used ('03 R50 91K miles) was a serpentine belt replacement. It also needed a new belt tensioner.

    After that replacement, when I start the car cold (not air temp, cold as in cold engine) I get a belt squealing noise for a few moments, apparently until the belt warms up. I have a suspicion this is also related to damp weather, but I'm not sure.

    Anyone else experience this? Should I care? Should I take it back to the place that did it to have them check the tension?

    I have has that happen from time to time when it really cold but then again my car lives in a garage.

    It could also be your idler pulley loose if it still the original one. (cheap fix)

    Thanks! The odd thing is there wasn't any squeal from the old belt. But then, almost the first thing I did was get the belt changed.

    Who is the maker of the belt? I use Gates belts.

    At your mileage I'd change out the idler for sure. Also have a good look at the crank damper pulley. Not sure if a failing pulley would cause that noise. It is odd you went from no noise to noise with a tensioner & belt change.

    I used to get that once in a great while, but since all all those parts were replaced on mine the sound has been absent.
