Squelch is an oxymoron to squeal, it's more likely that one of the serpentine belt idler pulleys or the tension pulley bearing is squawking during startup. In the winter cold, the rear alternator bearing often does this too so one needs to use a $10 engine stethoscope to identify the faulty part location so as not to waste $ replacing perfectly good parts for no reason as a swap and guess scenario where you throw good $ away at a hit and miss gamble. If you have a engine driven radiator cooling fan and that's the noise location, the fan clutch or water pump bearings may be bad, only on engine driven cooling system fan type engine setups.
Remove the drive belt and inspect by hand, all of the belt pulleys for drag and excessive bearing wear.
Don't be a dumb lemming, one $10 idler pulley is cheap, swapping parts is very hit and miss expensive!
The sealed belt pulley bearings often go many years past the point where they are noisy at start up before they fail, they will squeal at -25F temperatures and be normal. Squealing when warmed up is an issue! If they do basically quiet down after a few minutes of warm up running time, I wouldn't worry about it at all.
Also, if this is a front wheel drive car, the engine accessory drive belt does not run the electric cooling fan.
