Hello

 

I'm trying to figure out why on start up of engine

there's a squeel that sounds like it coming from alternator

or ac pump perhaps, then goes away after a few minutes.

 

I tried dressing belt but have not had adjustment checked yet.

Vehicle has 42k miles, seems a little premature for bearing failure.

Just started recently with cool weather.

 

Appreciate any comments/ sugeestions

 

thanks

I would think that it is a slipping accessory drive belt. (Belt dressing is only somewhat effective.) Startup the car, go look at the alternator and A/C pulleys and see if either are "stalled"; if not, I would assume that belt needs to be retensioned or, perhaps, replaced.

time to inspect and possible replace the drive belt. It could be other things too, but that is quite common. There are a few folks from the Bay Area who read this forum and if you have trouble with it I am sure somebody will look at it for you.

its a loose or bad belt. Belts can go at anytime as they do take a beating, but it is a little early. Could be just an adjustment
