Squeal at start up?

[MNBoxster]

Hi,

It could also be any belt-driven ancillary (PS Pump, AC Compressor, Alternator) with a bearing going dry/bad. Similarly, either of the Idler/Tensioner pulleys as well. The secondary Air pump can also make noise at start up. The one on my Esprit goes off every cold start for a few hundred revs until it warms and the vanes expand, but this is usually more of a chirp than a squeal. Hope this helps...

Happy Motoring!... Jim'99

Get under there and rub a little soap on it, if it goes away for a few days, your tensioner is likely too tight. Everybody thinks its too loose but it's generally exactly the opposite.
